Engine G4NA, Kia Motors All photos in the article from ABW.BY. The article is written in the materials of ABW.BY
It has long been known about the problems of G4KD gasoline engines, which are installed on KIA SPORTAG SL, Kia Optima, Hyundai IX35 and Hyundai Sonata YF. In 2014, all the above car models as well as on Hyundai Creta. And some others, Koreans began to establish a new G4NA unit. This motor has hydrocomathers in its design and is a completely new engine. Cars with him already traveled about 100,000 km. It's time to look inside the engine to find out whether Korean engineers got rid of old problems in a new power unit.
The test was conducted by Belarusian motorists, the authors of the ABW.BY portal per hundred in Minsk. KIA SPORTAGE FL 2014 cars were chosen as experimental cars, Hyundai IX35, Kia Sportage SL FL 2015. Let me remind you all three cars with a new engine of the NU, G4NA family, 2 liters.
The check method is as follows: Special spark plug hole in the cylinder automotive USB Endoscope, with an image output to the laptop screen. Thus, it is possible to see the wear of the cylinder, the presence or absence of scaling and nagar on the valves and the bottom of the piston.
Sportyj 2014, Mileage 44,000 km
The first car drove less than 50 thousand km, was operated carefully (according to the owner). Served by the official dealer in Minsk. Oil changed according to the regulations, every 15,000 km. Foured Motul 5W30. Only 95th gasoline refuel. The owner complains of the "cold" engine.
We explore the first cylinder for the presence of scaling. On the front wall there are vertical scratches that reach the top of the top.

On the back wall (the one that closer to the graduation collector) scratches even more and deeper. Also there are strange round spots, unknown origin.
In the second cylinder the same. On the bottom of the piston is visible to Nagar.

In the third and fourth cylinders of Zadirov even more. It can be seen how Hon is erased. Let me remind you, this motor has passed only 44 thousand. No accounts should have any speech on such mileage.

HYUNDAI IX 35, Mileage 24,000 km
The next car was also served only on the official service. The oil has already changed three times, not in running, but by years.
The first cylinder with scratches, both on the front and on the rear walls.

In the second and the third also begin to form ups.

The fourth scratches are the deepest. On the bottom of the piston there is a nagar.

Sportyj 2015, Mileage 43,000 km
The third experimental also passed a bit, and was operated very carefully. All that was held at the official in Minsk. In winter, knocks on a cold motor.
In the first cylinder, which is no longer surprised, there are scratches.

In the second again, mysterious circles, similar to the traces of corrosion. This is the second new G4NA with a similar picture, but there are especially many spots.
.jpg)
In the third cylinder, the deepest bulgers, Hon is actively erased. And this is 43 thousand mileage.

In the fourth loans less, but they are.
What is the cause of such strong cylindro wear piston group It remains only to guess. There is an opinion that this is a local overheating of the pistons caused by the wrong design. Some suggest that the case in the collapsed catalyst, the ceramic dust from which enters the cylinders and acts as abrasive.
In the car number 3, compression was performed, it showed the result of 12 kg / cm2, which is the norm. There are no oil consumption of all three cars. The only manifestation while this is a cold knock on the cold.
As you can see, the new line of motors of the NU family has the same diseases as Old Theta 2. Did the KIA engineers did not consider the problem of mass breakdowns of the previous unit on runs up to 150,000 km. How much will go G4NA to the cap. Repair remains only to guess. In any case, the disappointing conclusion, Kia and Hyunda recent generations Not for operation more than 200 thousand km. "Disposable" motors are apparently designed to cause the purchase of a new car, after 5, a maximum of 7 years of operation. Should I buy a used Korean, judge for yourself.

And the Gregates of the transmission car got quite good, but their resource was accurately designed for the maximum warranty period of five years.
You can suspect Koreans in creating a "disposable car", but rather, we are simply about the high culture of production and maximum savings.
Five years or about 120-150 thousand kilometers is a resource, after which the transmission service ceases to be budget. And sometimes it can be seen that the transmission could serve and more, but in the instruction manual did not reflect the need for service. For example, on the crosses of the cardan shaft there is a press oil, but there is no appropriate procedure among the maintenance operations. And after 150 thousand Cardan crossmen, most likely, you just need to replace.
"The ill-shrus disease" on cars after restyling can happen before, on the mileage about a hundred thousand. The reason for the "disease" lies in a serious "puncture" of the Slovak assembly: the inner right hinge did not report lubricants. In the rest of the shurts, it is also a bit, but almost always enough for the "warranty" lubricant. Particularly leaning car owners add lubricant alone, so do not be surprised by non-original clamps, but be alert when buying and listening to the hinges for the stuffs.
On all-wheel drive machines, in addition to the cardan shaft to a five-year-old runway, it usually fails to connect the rear axle coupling. She here is simple electromagnetic and, in general, not difficult in repair. Most often, the replacement requires the front bearing, it is worth a maximum of rubles 600 on parts and work. Friction clutches usually remain integer, but the bearing due to ingestion moisture and dirt will work out.
The same dirt displays a magnet of the coupling drive, and it suffers mostly wiring to a power block, so you can restore everything. But sometimes there are difficulties with disassembly: if the coupling is not blocked when the power is applied, it is not always possible to stronger the input shaft nut. Attempts to block the clutch with alternative methods in this case, often lead to mechanical damage. However, the price of a new coupling about 75 thousand rubles is not enough, but not exemplary. Of course, this node can be found on the disassembly, which will be much cheaper.
Angular gearbox, which is often loudly called " dispensing box"It is usually held noticeably longer. If you regularly change the oil and follow the leaks, then it is almost eternal. But it is necessary to follow him: after 150-200 thousand, the grooves can squeeze, after which the bearings will first suffer, and if you run the situation, the case cover will fail and trees themselves.
In machines with manual transmission, there is one trouble: the bolt of fastening the switching mechanism is unscrewed, as a result of which the transmission starts to turn on very badly or not included at all.
The gearbox itself is quite reliable when operating in a pair with gasoline two-liter engine. Resource released Bearing Usually does not exceed six to seven years and 180-200 thousand mileage kilometers, which is on average a little more than the deadlines of the drive of the drive. But in the cold regions, he may fail much earlier. Fortunately, Sportage clutch replacement is quite simple, especially in front-wheel drive cars. It is not even necessary to remove the subframe, and the parts are not very expensive. For example, the original bearing is only a half thousand, and non-original - and less. True, the item from serious brands is much more expensive than the original, the same SKF bearing is about six thousand, but, judging by the reviews, it is not afraid of frosts.
In the photo: Kia Sportage "2008-10 With automatic transmission, everything is not so bad. Basically, there are very reliable "quasvish" series F4A42-2 / W4A42. With a 2.7 liter engine, they put a stronger F4A51 / W4A51. All transmissions lead their pedigree from the "machine guns" Mitsubishi, which are largely unified with Chrysler boxes: at one time, the company successfully collaborated.
Four-stage boxes of the F4A42-2 / W4A42 series for front and all-wheel drive cars are respectively known for their reliability. They are afraid of overheating, but otherwise they still tolerate even very tough operation. They, like the SUBARU automatic transmission, has an external oil filter On the housing, which allows you to keep the hydraulicock clean to the last. True, the high torque box does not like, and lovers have to drive along the high speed highway (especially with a 2.7 liter motor) fails the needle bearing of the fourth transmission and the rear gear suffers.

Late automatic transmission versions are somewhat strengthened, but, nevertheless, you can face this trouble. With a rare oil replacement and filter, solenoids and a hydroblock plate suffer primarily, and in the case of overheating - GDT and rubber seals, after which the box gradually dies due to oil starvation and progressive contamination of the hydroblock.
If we talk about reliability in numbers, then 150 thousand kilometers this box is always withstanding, even if the oil has not changed at all, and 200-250 thousand is a standard resource of high loads, but regular maintenance. With neat operation with a two-liter motor, regular oil replacement, with an external automatic transmission radiator and not in Russia, you can find quite lively copies with a mileage for 350 thousand kilometers. In general, during normal operation, the box allows you to count on 200 thousand runs until the first small repairs are replaced and replacing the LDT locks.
Quite often there are minor problems with failures of sensors of input and output revolutions. With repair and spare parts, there will be no problems: before last year, the VERNA / Solaris was established constructively similar, very successful A4CF1 / 2 automatic transmission.

With contract automatic transmission, everything is not so simple. Theoretically, Sportage can be put in a whole bunch of boxes from Mitsubishi, but in practice it accounts for quite a lot: at least another box control unit is needed, and there are serious differences in a mechanical part.
A more torque 2.7-liter V6 was significantly more powerful automatic transmission F4A51 / W4A51. It also has four steps, but there is more significant reserve for a torque. This automatic transmission "digested" even the engine volumes of 3.5 liters, so that with a motor 2.7 it is almost eternal. When runs, more than 200-250 thousand can be expected to expect jerks and small delays in shifting transmissions due to the wear of the EPC solenoid, and the most frequent cause Including emergency regime is the failure of the speed sensors.
At Sportage problems are extremely rare, but by the experience of other machines with this "machine" in the future you can expect the following resource problems: wear of the output planetary transmission and its bearing, wear of gears and the case of differential, as well as Drumct drum and its brake tape.
With the timely replacement of oil, the resource of such automatic transmission significantly exceeds 300 thousand kilometers, and lead to serious breakdowns Only can only errors in operation.
Motors
Hyundai / kia engines are very reliable, only engine sensors and cooling system can take.
Current radiators - a typical picture. If the owner applies to the number of specially economical and pour the sealant into the cooling system, the motor from detonation and the disturbance of the CHC plane dies simply and easily. When buying it is worth checking the condition of the nozzles, which radiator is installed, what fans, and whether the wiring is marked with them.
In the photo: Kia Sportage engine Materials are not the best here, therefore the components of the system often change and "collective farm". The latter is due to the fact that a number of Chinese radiators fit very conditionally. All gasoline engines have a fairly conservative and weak crankcase ventilation system, so the leaks of oils are often found, just like a dirty throttle valve. The resource of catcollectors is also small, it is better to replace them after 150 thousand runs. In the extreme case - remove the scored, which is typically for cars from cold regions.
The exhaust system does not differ in particular corrosion resistance, it is often necessary to change it in the ten-year vehicles, and the corrugations are only enough for a hundred thousand runs.

In the power system, not the most successful fuel filter installed directly on the fuel pump in the tank is applied directly on the fuel pump. The main engine at Sportage II is the Motor of the Beta II G4GC family. This two-liter petrol motor Also leads a pedigree from Mitsubishi aggregates, but differs from Japanese a number of original solutions.
Timing the timing here is mixed, with a belt and chain. Remember how this is done on 1.8-liter Motors EA113 Concern VW of the end of the nineties? The graduation camshaft is driven by a belt from the crankshaft, and the intake camshaft is a chain from the graduation, at which the GHR phase regulation system is at the same time. In the case of KIA, the system is quite reliable, the chain can pass 200-250 thousand kilometers. The timing belt is better to change according to the regulations, every 50-60 thousand kilometers, and necessarily together with the rollers: the bearings are disgusting quality.

The phase management is "the thing in itself": with the unsuccessful choice of oil, it may require the replacement of coupling and valves after the first hundreds of thousands of kilometers, but usually honestly serves before replacing the chain. There are no hydrocomathers in the motor, and the gaps here are prone to "floating", so the adjustment is to spend noticeably earlier than 90 thousand kilometers. Otherwise, there is a risk of damaging the camshaft, which is pretty soft.
The design of the oil pump turned out to be very successful. It is gear, made in the front wall of the block. With the wear of the pump gear, you can do the replacement of only the cover on the repair - greater thickness. The pump drive is made from a separate belt, like motor chain in the Timing drive.
In general, it turned out a great engine with a good resource of a piston group, which is about 300-400 thousand kilometers to the first overhaul. The motor is distinguished by a convenient layout and small sizes.
But you must admit that anything perfect anyway does not happen. The management system is weak, and the hinged equipment after 150-200 thousand mileage kilometers requires close attention.
Hard sound is not a malfunction, but a feature caused by not the best study of the chains and crankshaft vibrations. It is for this reason that it is better not to pour low-grade oils into the engine with mileage: may not withstand the liners.
A larger 2.7-liter V6 motor is the G6BA family of Delta II. In many ways, it is similar to the previous engine: it has the same combined timing timber with a belt and chain, similar features of the layout of the crankcase ventilation system and ignition.
The engine block is not a cast iron, but aluminum, but with cast iron sleeves. The resource of this motor is also excellent: it is quite possible to drive 400-500 thousand kilometers, in any case, on passenger cars.
The feature of the design is to use the belt hydraulus, and this is not the most successful option: if the oil freezes during winter launches, the belt simply slipks. Otherwise - the reliability itself, unless, of course, do not overheat.

The main troubles deliver inlet with dampers, weak exhaust manifolds and a low resource of catcollectors, which are here two at once. Nevertheless, it is probably one of the most reliable motors of the XXI century. True, power in 173 hp For the engine of 2.7 liters - this is not a god of news which indicator, but also European problems with high operating temperature and adjustable thermostat there is no.
The diesel engines of the D4EA series cannot be attributed to especially reliable primarily due to fuel equipment. To run in a hundred thousand kilometers, even in Moscow or St. Petersburg, all the nozzles and the high pressure fuel pump are usually asked to replace. Moreover, it will also have to rinse the fuel line, which is polluted by wear products.
Frequently burns in the glow candles, and the ECU algorithms are strange and not debugged. So the "hanging" of revolutions after the start by cars before restyling was the usual thing.
The experience of the operation of diesel engines is relatively few, but the output can be done: the motor is quite troublesome, and knowing the features of the operation of diesel engines in Russia, this motor becomes far from the best choice For a relatively light machine.

With small runs, the car surprises almost complete failure. Yes, inside the poor, the design is an amateur, but there is enough space in the cabin, and the car is not so bad on the go. IN direct comparison With the best of Europeans and the Japanese, it loses, but with ease it makes glasses a low purchase price and especially exploitation.
With the growth of the mileage, the consequences of savings are beginning to affect. After the first hundred thousand - mostly cosmetic, and after one and a half hundred thousand one can expect a whole "bouquet" of problems, and both from the suspension and transmission. And even the most reliable gasoline engines are ready to invest their contribution to the cost of repairs. Body is not bad, in any case, for now. But the trend is scheduled not the best: the absence of protector protection leads to a rapid growth of defects. Even with a high level of color it causes concerns for the further fate of the car. Fortunately, cars with a little mileage is enough, weak places Not much at all and you can choose something like.
The best choice is undoubtedly gasoline engines, and it does not matter, with automatic or manual transmission - they are all reliable here, but without a full drive it is better to do. However, if it breaks, you can simply remove the coupling and the cardan shaft and cannot be denyed. The main advantages of the car will preserve, and the permeability among them did not matter even initially.
In Russian club forums and social networks, alarming bells about the reliability of the 2.0-liter Kia / Hyundai G4KD motor, associated with the appearance of the knocks in the cylindropional group (CPG), began to appear on social networks. At the same time, in Belarus about problems with these motors, it is not heard. What is this - features of Russian operating, as some say, or still technological miscalculation? To find out, journalists ABW.BY gathered several cars and sent them to the Endoscopy of the CPG.
Let's start with the fact that the engines "clones" G4KD (THAETA II) and 4B11 are built on the architecture of the Global Engine Alliance - the Alliance created by Corporations Chrysler, Mitsubishi and Hyundai, but at the initiative of Hyundai. Each company introduced some adjustments to their brand, but the architecture remained uniform. The main part of the development was carried out by Hyundai.
The motor is completely aluminum, contains four valves per cylinder, two camshafts in the cylinder head (DOHC), as well as a system for changing the phase distribution with electronically control Mivec (intake and release). Accordingly, on korean cars The letter designation is G4KD, on Japanese - 4B11. Motor was put on Kia Cerato, Kia Optima, Kia Sportage., Hyundai Elantra, Hyundai IX35, Hyundai Sonata, Mitsubishi Lancer., Mitsubishi Outlander, Mitsubishi ASX. And numerous models of American production Chrysler and Dodge.
On the basis of this unit, the engine G4KE (Theta II) / 4B12 with a working volume of 2.4 liters was created. In addition, on the basis of 4B11, 4B11T Turbops was created for sports Mitsubishi Lancer Evolution and Mitsubishi Lancer Ralliart.
"I recently addressed the owner of the negarantine Kia Sportage," says the car master from Minsk. "The car arrived from Russia a year ago, there are all service documents - served at the dealer. Here the owner did not drive 8,000 kilometers. After 120 thousand ordinary operation, the engine boomed. Initially, the owner went to the Hyundai dealer. They listened the car, they said that the piston was knocking, they say, the burdens, the motor will be shifted, piston change - we know about the problem ... We did not believe, went to endoscopy. It turns out that the guys from Hyundai were right . What I saw is normal for old engines with runs of 400-600 thousand working on Tine, with a leaky toe instead air filterBut not at a four-year-old KIA with a careful mileage of 120 thousand. Cylinder walls in jackets, long, abundant and ugly. So far, there are still shallow, as it stumbled recently, approximately kilometers of 500 years ago. Memorial compression showed 13-12-13-13. That is, the motor is still "alive", but in the second cylinder there is already pressure drops. Another 10 thousand kilometers, and will consume butter on the avgar and the "sampling" in the oil refining neck. After 50 thousand it trips and "die." If not evincible before. "
Having removed the pallet and finding the metal powder in it, the motor was dismantled and dismantled. It turned out that the jacies are present in all cylinders on the front and rear walls. At the same time, the most damage in the second, third and fourth "pots".
It goes without saying, pistons suffered. Running on the Internet, they found out that the case is not alleged.
On the Russian Forum of the Kia Club forum already 640 (!) Pages of discussion of this issue, there are many cases of problems with the CPG G4KD, and there are suspiciously many videos about Zadira and Korean Motor Videos in Youtube. The symptoms are as follows: in the period 50.000-150.000 km the engine appears on the cold "on the cold". With mighties, the knock is enhanced and stops disappearing as it warked. The autopsy shows the presence of jackets on the "skirts" of the pistons and the walls of the cylinders. And it does not matter where the car was served, at the dealer, on third parties or in the garages.
What is interesting, in the US, there was even an revocable campaign, touched half a million (!) Machines with engines of Theta II series, in which the engine indicated by us. In addition, a campaign was conducted to extend the guarantees on the engines. But there is a slightly different problem associated with blocking metal chips of oil channels, which led to oil starvation and stop of the motor.
Nevertheless, in Belarus sold a large number of Korean cars with these engines, and it seems to be heard about our forums about the problem, unlike Russian forums. Initially abw.by found out about the question of the history with the Kia Sportage engine from the Minsk Automaster: It seems that the mileage is small, and the motor has already demanded repairs due to the jackets.
To find out if these problems are not inflated, ABW.BY contacted Kia Sportage Fans Club.
In total, four cars were found in Minsk (in two cases, the knocks were already "on hot"), of which three cars eventually took part in our "disassembly". Also invited the owners of two cars with a mileage of 70.000 and 140.000 km, which were not complained about the knocks.
Endoscope has problems. Saved from Russia "Video Wheel Pro" does not see the walls of the cylinders. It turns out that endoscopes in Minsk can be considered, no. There is only an individual entrepreneur, a car machine with an experience, which is engaged in engine endoscopy. By the way, it was almost a month ago a car was diagnosed, the internal content of the engine of which was shown at the beginning of the article.
Endoscope at the Master Special Medical. The probe can be rotated in any direction and bending with special "twist". The walls of the cylinders are visible very well. But the problem is that the device does not make a photo. There are two more Chinese electronic endoscope, but problems arose with them in the process of work. In general, we look at the cylinders with a medical optical endoscope.
The first inspected car of 2011 was already driving 87,000 km. Purchased new in the Belarusian dealer, after which was operated by one owner. After the end of the warranty, the stuffs "on the cold" appeared. Over time, they were present and after the engine warming, the truth is noticeably quieter. At the same time, small vibrations began to be felt before warming the motor.
The owner of the day before the experiment visited the KIA official dealer service station. The endoscope of the "official" was not found, but the mechanics on the hearing were determined that in the cylinders of the jackets. They say, this is a well-known problem, you need to open the engine and change the cylinder block worth about $ 4,000.
The owner claims that it goes well, the first kilometers presses the "gas" carefully. The car is serviced at the dealer in a timely manner. Moreover, he even reduced the interval from 15,000 to 10.000-12.000 km. In Carter, then the oil, which is recommended by our dealer, is Motul 8100 5W30.
Remove the coils, get the candle. And we see that the insulators of candles are punched. What is interesting, this picture was observed in all viewed Sportage, where NGK candles were used.
Moreover, even the candles that have been replaced less than 10,000 km back. The regulations of their replacement - as much as 30,000 km. Lot. But on one machine there were whole Bosch, so, most likely, the case is in the candlelight.
We look at the endoscope in the cylinders - we discover the strong incommensuits in the second and third cylinders, which, a total of two sides, occupy almost 2/3 of the entire circumference. In the fourth there are less than, but they are. The first cylinder is clean. According to the vehicle, he did not see scores in the upper part of the cylinders, which says that the scratches leave the "skirt" of the piston.
Running ahead: Nagar on the bottom of the pistons is found in all machines, somewhere less, somewhere else. The amount of deposits Master qualifies as "average", but on these runs there should be no such picture at all.
What's next? Over time, the problem progresses. The knocks will be enhanced, the strong maslip will begin. After a while, the motor will simply stop starting. Expensive repair of the engine (replacement of the cylinder block or sleeve) is no longer avoided. When it happens exactly, it is difficult to say.
The next car is 2011. Also bought in Minsk. At the moment, the mileage is 109.000 km, the warranty is over. The owner is concerned about the knocking "on the cold". The car was serviced on time, in the frost, a short time he warmed up, driving style calm. Total and Zic 5W30 oils were used. The dealer stopped serviced after the third that.
However, listen - the knock is perfectly audible and "on the hot". From all cars here we heard the most loud and clear knock. But even it is not heard in the cabin after heating.
As expected, the jackets were found in all cylinders. Moreover, the most problems in the second and third, where the bulbs are located on a large area around the circumference of the front and rear walls. In the first and fourth cylinders, there are fewer problems, although the loops are concentrated relatively in a small zone from the exhaust manifold, but they are very deep. Nagara on the bottom of the engine pistons of this car Most. In general, the most running option. But, according to the owner, Zhora oil seems to be not yet.
On the knock owner next car did not complain. The mileage is only 76.000 km, the year of release - 2012, the owner bought it in Russia, when there were 42,000 km on the odometer. The service book with marks about the passage is in stock. In Russia, shell 5W30 oil was flooded in 11.000-12.000 km, in Belarus, the Kroon-Oil 5W30 oil is changed at 7000-8,000 km. Orders-outfits are used original spare partsTherefore, the owner hopes to preserve the guarantee in Russia.
In the first cylinder there are no loans, but in the fourth they showed strong scratches in a small zone from the exhaust manifold. In the second and third - small bully from the issue. At the knocks, the owner did not complain, but the motorist still heard "on the cold" small "clan". There is no oil consumption.
The next car came from Russia in 2015. At the time of purchase, the mileage was 86.000 km, now 115.000. The knocks after starting the engine appeared when the owner read the forums. Yes, maybe many people simply do not hear them.
The presence of problems in the cylinders was confirmed. On the walls of the second and third cylinders - the middle jackets from the exhaust manifold. The first cylinder is clean, in the fourth there is a pair of scratches on the back wall. Nagara relative to other machines is a bit, but still clearly not at 115.000 km of mileage.
It was this car that journalists tried to remove Chinese USB endoscopes. The first saw only the piston, the second one was recorded vertical scratches on the wall of the cylinder. True, rotate the camera managed to a small angle, so the wall is visible only at the very bottom. After five minutes of attempts, the probe overheated and the device turned off forever.
By the way, pay attention to the ends of the candle housing. It is in the second and third candles that carbon deposits are noticeable. So, if you have suspicion of jackets in G4KD, but there is no endoscope, you can try to unscrew the candles and look at the ends of the case. Black sediments will say that in the cylindropional group is not all right.
In general, the car is still driving, how much will erupt - it is unknown, but the problems have already begun.
Black Sportage 2012 I ran the most - 140.000 km, bought with a mileage of 40,000 km in Russia. There is practically nothing about maintenance there. The first fusion oil was surprised by the owner: according to the form or did not change it for a very long time, or it was counterfeit. The sticker says that shell oil was pouring. After purchase, the owner uses Zic 5W30. On the oil probe, the black crust of sediments was formed - the owner had to count it for a long time. The engine sounded very loud, but after the service began to work fine.
In Belarus, the car was serviced properly and in a timely manner, but the owner admits that he loves to press the Gaza pedal well. True, it makes it only after a complete engine warming up, before that it goes carefully. Also installed autorun, so the engine in front of the start is heated for some time at idle.
The owner did not declare any foreign sounds, it was a completely random car, but "on the cold" knocks still audible.
We looked at the oil level, they estimated which it was 5000 km back, - a small consumption is still present, approximately 200-250 g for 5000 km.
In the first cylinder only one scratch. The second cylinder from the output is medium-sized jackets, and the same as the previous car. In the third cylinder, medium scratches are located on both sides, in the fourth - only on the back wall, but deep enough. The angle of accommodation is 15-20 °.
Carbon deposits are on the ends of three candles, except for one - the first cylinder, on the wall of which only one scratch.
What is the result? We disassembled one engine. There were five more engines - they discovered loops in all. In three out of five cases, the owners declared the presence of a knocks - these cars were taken on endoscopy specifically to find out the reason for the knocks. The other two are chosen completely by chance, about the knocks and any problems the owners did not speak.
To be honest, it is strange that in all three cars with the stated presence of foreign sounds there will be any problems. After all, it can knock anything or not to knock. A car enthusiast can take for extraneous sounds the usual dynamics of nozzles, problems with the timing of timber or operation of unregulated valves, since G4KD hydrocompensators are not, the valves must be adjusted. But no, in three cars - Zadira. In addition, they showed out in cars whose owners did not hear any knocks ... And another car with a knock and did not reach the endoscopy. In general, it is surprising.
Any pattern of identifying could not be revealed. Carters from these engines are distinguished: there is both 4-liter and 6-liter. On the inspection, there were mainly cars with a filling capacity of 6 l, but it is unlikely to influence something. Oils were used very different. Service, as the owners assure, was carried out only on the regulations, and some of them reduced the oil replacement interval. Two cars were bought in Belarus, four are driven during the favorable course of the ruble from Russia. Some cars were served by official dealers, There are service documents, others - on unofficial hundred. "Automatic", "Mechanics"? No matter.
The only thing that was detected - different machines Zadira are developing with different "intensity". At one of them, on mileage 115.000, the beginning of the occurrence of problems, and the second on 87,000 km will soon need to be repaired. Also, judging by the reviews, the problem did not touch the owners of Mitsubishi, under the hood of which a copy of G4KD - 4B11 is installed. At least nothing hear about it.
There is an opinion that the problem lies in poor-quality services russian cars, counterfeit butter, bad gasoline and aggressive ride, especially "on the cold". Of course, illiterate exploitation aggravates the problem, but if it were the main reason, then half of the Belarusian and Russian cars would have stood in line on the engine overhaul.
You can guess about the reason before infinity, besides, we are not Kia or Hyundai engineers, we have no statistical data. But there is an assumption of experienced carkers that everything is fault - a mistake in the calculation of thermal extensions. As it seems to us, the version looks very convincing.
"When designing any engine is calculated and the coefficients of the temperature expansion of the body are calculated," said Aleksandr. - In this case, most likely, we are talking about wrong selection The heat gap in the pair of "piston is a cylinder" or an incorrect choice of piston material and its shape. When the engine is running, especially in the increased range of revolutions, the oil film from the walls of the cylinder is disappeared with the transition to semi-dry friction. The consequence of such an engine operation is jackets or "grab" on the walls of the cylinder. The increase in the gaps in the assemblies of the CPG due to semi-dry friction generates the piston breakdown and the occurrence of the knock in the engine caused by the "skirt" of the piston when the cylinder wall is driven. The situation aggravates the high degree of forsing and the temperature regime of the engine, visually insufficient area of \u200b\u200bthe water channels of the block or the insufficient efficiency of the water pump. In favor of this version, it is said that always the most damaged - the second and third cylinders, that is, the most thermally loaded to remove from the water pump. Based on the above, most likely, there is a constructive miscalculation.
Can the incorrect operation of the CU cause such serious problems with the engine? Not. Riding on an immentable engine can be exacerbated, but it cannot be the main cause of a malfunction. In the global engine practice, there are a lot of motors with aluminum blocks, and with the walls of cylinders such problems does not occur. For example, DVS RENAULT / VOLVO B5254 or a turbated six-cylinder version B6284T. The manufacturer is laid by the admission when calculating the CPG, as well as the absence of the need for a special engine running after the assembly.
Does the quality of fuel and fuel affect the occurrence of jackets in the cylinders? No, does not affect. The presence of at least one detonation sensor in the G4KD injection system will not allow the engine to work on fuel mixescausing devastating detonation due to poor-quality fuels. The nature and type of wear can not be caused by detonation, as the "skirt" is damaged, and not the bottom of the piston. There are no plates that burst rings and interclause bulkheads. Quality fuels unreasonable replacement expressed in the form of resinous / varnish sediments on engine parts and cause premature liners wear crankshaft, "Logging" rings and increased oil consumption. There were no such problems to reveal such problems. "
Often in the blocks of engines there are oil nozzles, which are designed to water the piston oil from below, thereby cooling them, as well as improving cylinder lubrication. In the atmospheric version of this motor there are no such nozzles, they are only in the turbocharged version of the Japanese 4B11T, as well as in all diesel engines that are put on Sportage. Some motorists believe that it aggravates the situation with the G4KD absence, the piston overheats, which leads to a decrease in the gap.
True, there are engines and without oil nozzles, which do not have problems with jackets. In nozzles, it is difficult or not, it is difficult to say, but at will, you will certainly be embedded in a block with overhaul. It may also possibly help installing a water-oil heat exchanger from the "senior" engine G4KE, as the lack of circulation of oil "on the cold" in winter also exacerbates the situation. True, we did not conduct any calculations and expertise, so all this is only assumptions.
How to solve the problem if the motor staped and began to consume butter on the avgar? Two options are available: or replacing the cylinder block, which is very expensive, or the plot of the block, which is also expensive, but at least it makes sense. The second option is most common. Standard pistons and rings, sleeves (suitable from Toyota), a set of gaskets and other necessary parts for repair will cost, as we counted, about $ 1000. With work and other trifles, it turns out a round sum: for example, for repair Sportage. From the very beginning of the article, the owner gave $ 1750 - a lot. At the same time, how many motor passes after the guilzovka, it is not known to anyone, there are enough nuances here, hardly as much as the factory engine. If the car is under warranty - you are saved: there is a chance that the unit will be replaced under warranty.
Replacing the aggregate on the contract? Also an option, but they are still not on sale. And if they appear, they recommend buying such a used unit only after the CPG endoscopy.
It is not yet known whether this problem, the statistics of the automaker and technical examination of journalists do not have. While in Belarus really fixed single cases.
But in any way you need to be guided by a number of recommendations. High-quality oil changes at least once every 10,000 km, to pour only 95th gasoline. On traffic lights forget forever - the heavy loads of this motor, apparently, does not like. It is important to carefully ride until the motor output on operating temperature. At the same time, "in the tension" is also not worth riding, but at the same time the "gas" pedal must literally stroke. Especially careful should be in winter, it is recommended to warm the engine before starting or installing an autonomous heater.
And what will say representatives of the exclusive distributor brands Kia. In the Republic of Belarus, the company "Autopalace-M"?
"The service of our car center received single appeals on the specified problem with the G4KD engine. Basically they were associated with non-compliance with the rules of operation of the car: tough exploitation, ignoring winter conditions, using low-quality fuel and fuel, etc. Almost all appeals from legal entities, which such attitude towards the car prevails.
Warranty obligations are always executed if the Customer's claim is justified. In particular, we, as a rule, cannot prove that the car was tight operation, for example, high speed on the cold engine, then the vehicle assembly is subject to a replacement for warranty. In this case, such cases for the specified engine was very small. There can be no speech about the mass.
We recommend that all car owners carefully read and follow the instruction manual, carefully refer to the recommendations of the masters, to use only high-quality fuel. This Council is universal for owners of any cars with any motors.
Are there any problems with the new generation of crossover? Specified Engine 2.0 was used for the models of the previous Sportage. New model Sportage Qle, which comes to Belarus from May 2016, is equipped with a new engine. "
Hyunde Avtograd LLC also suggests that cases with jackets in the engines of their Hyundai IX35 are single. Perhaps it is.
While we will not say anything 100%, but the story with G4KD is strange. Yes, six cars are a drop in the sea of \u200b\u200bcars sold with this engine (not only Kia Sportage), we really have a lot. In the Minsk club of Sportage lovers, already 50 cars with runs around 100,000 km. And yet, no one of them did overhaul, most of the owners on the knocks do not complain. Nobody is going to change cars in the club too.
But such noise on the Internet arises for no accident, and the results of our endoscopy of five engines and disassembling one, to put it mildly, surprise. In general, time will show.

This motor was installed on both Kia Sportage 3 and the fourth generation. They were equipped with MCPP and automatic transmission. It was used in primary and medium-sized equipment. This is the most common engine Sportyj in our country.
Motor power 2.0 is 150 hp, torque 191 nm. This is a four-cylinder, petrol aggregate With 16 valves and a system for changing the phases of gas distribution on both shafts. The fuel supply system to the cylinders is implemented on the principle of MPI or distributed injection, which gives the Motor the following advantages:
- easy design
- high maintainability
- low value of spare parts and repair
- ability to pour 92nd gasoline
Motor New Kia Sportage 2017 2.0 MPI DOHC 16V Gasoline
It is the gasoline engine 2.0 that is considered the most trouble-free and inexpensive in service among the engines of sports not only the third and fourth, but also the second generations. Unfortunately he has disadvantages:
- Relatively low power, in comparison with other power units of this model;
- A fairly narrow shelf of the moment, the maximum - with 4700 rpm;
- Comparatively high fuel consumption, in sports with such a motor it is 8.5 liters in a mixed cycle;
Engines 2.0 rarely deliver cotton to the owners of the machines with them. In terms of faults, mostly, the little things of the type of trim, swing turns and a knock on the cold. Eliminate usually replacing candles, fuel filteradjusting valves. In general, the modification of Kia Sportage with the engine 2.0 and mechanical box The gears can be considered the most reliable and unpretentious in the ruler.
Engine 1.6 T-GDI
Motor 1.6 Turbo, perhaps the most interesting of the power units Kia Sportyj. The company's engineers used modern solutions in it, which allowed to get high power And torque in a wide range of revolutions with a decrease in fuel consumption. This became possible due to the technology of direct fuel injection into the GDI cylinders, the use of the turbocharger and the system of changing the phase of gas distribution. As a result, the power of such a motor was 177 hp. At 5000 rpm, and torque 265 Nm in a wide range from 1500 to 4500 rpm. Machines with such an engine are equipped with a DCT robot and therefore you can not think about the fact that you have a gearbox, just click on gas and the car accelerates almost any revolutions.
Naturally, the T-GDI motor has disadvantages. They are associated with the complexity of the design, the presence of a turbine and equipment for supplying fuel into the cylinders. The supercharger is called durable difficult, in addition to it, the high pressure fuel pump can be out. Thus, more or less serious repair of such an aggregate will require significant costs and relevant qualifications of service staff.
The cause of problems with the fuel system of this motor often becomes the use of poor-quality gasoline. Although the engine is adapted to the use of 92th gasoline, it is not recommended to do this, GDI technology in Korean cars requires the use of high-quality fuel and fuel.
If you look at the reliability of the unit as a whole, it does not arise to it, subject to timely service, the use of high-quality engine oil and the normal will be able to degrees much more than its warranty period.
Since 1992, four issued generation Kia. Sportage with diesel and gasoline engines, mono- and complete drive. Truly competitive in segment compact crossovers Kia Sportage became in 2004, after the presentation of the second generation, built on the same platform as - Hyundai-Kia J3. Less often in Russia there are versions of the first generation, which were collected at the factory in Kaliningrad.
Kia Sportage Engine
First generation
Kia Sportage of the first generation was produced from 1993 to 2006. Completed five different gasoline and diesel engines. The volume, as a rule, was 2.0 liters, and the power ranged from 63 to 128 horsepower. Although the KIA Sportage motor line is presented with a 2.2-liter diesel engine, borrowed from Mazda.
In Russia, four-cylinder power units issuing 118 or 128 liters are most common. from. Engine Kia Sportjage works in a pair with a five-speed mechanic or a four-step automatic machine. Average flow 100 km varies from 8 to 14 liters.
Versions designed for the domestic market are not particularly picky for fuel quality. Oil, on the prescriptions of the manufacturer, you need to change every 12 thousand km. But with permanent operation in urban environments, it is desirable to reduce interservice runs up to 8-10 thousand km. To avoid overheating, you should take care of the replacement of antifreeze every 50 thousand km, as well as prophylactically make flushing radiators.
The owners of Kia Sports I generation I rarely complain about the engine. The main claims are associated with corrosion of body, poor noise insulation, noisy crushes, weak stabilizer bushings. Most breakdowns are associated with the old age of the crossover. The power units are reliable and unpretentious, although the KIA Sportage diesel can deliver problems when using a low-quality diesel fuel. It often fails. fuel pump, CRITTAGE CRP and crank-connecting mechanism are critically wear out, problems with launching on the cold appear.
If you are the owner of the Diesel Sport I generation, to increase the resource of the power unit and fuel system Use. The additive will increase the cetane indicator by 3-5 units, reduce the flow rate of 10-15%, will reduce the wear of the motor under load, protects fuel injectors. It removes water from diesel fuel, thereby facilitating the start on the cold at minus temperatures.
Second and third generation
The second generation crossover was produced from 2004 to 2010. It was already built not on the frame of the staircase type, so it became less adapted to off-road. The KIA Sportage II generation was completed with gasoline engines with a volume of 2.0 to 2.7 liters.
In 2010, the second generation was replaced by the second generation. The crossover was equipped with an anterior or complete drive, a five-speed mechanic or a six-speed automatic machine.
For Kia, the second and third generations, the following power plants was used:
1) D4EA. - turbocharged four-cylinder engine volume 1991 cubic meters. See Power is 113 liters. from. With solid runs in the motor 2.0 CRDI, compression gradually decreases. This negatively reflects on fuel consumption, power, problems appear with the start of the motor to the cold. Over time is clogged eGR systemDue to the wear of the turbine and the CPG in the exhaust, particles of oil, soot, which leads to a deterioration of thrust. Serious problems In Kia Sportage, the D4EA motor appears during runs over 200 thousand km.
2) G4GC. - two-liter gasoline engine with a cast-iron cylinder block, which was widely used for cars implemented in the Russian market. This is an ordinary atmospheric with a capacity of 143 liters. from. The volume of oil in the lubricant system is 4 liters.
The resource with proper maintenance and normal operation exceeds 300 thousand km. This KIA Sportage Beta II series is equipped with a CVVT system, but does not have hydraulic components. Therefore, it may be necessary to adjust the valve gaps when running less than 100 thousand km. It is important to change the belt in a timely manner. It follows every 60 thousand km, because when it is gap, the flashes valve.
Among the shortcomings of G4GC are high noise, increased vibrations, characteristic jerks during acceleration. Sometimes they freeze the revolutions, to eliminate the problem, reflash the ECU.
3) G4KD. - two-liter gasoline engine Kia Sports with an aluminum block of cylinders. Power is 150 liters. from. IN russian conditions Its resource reaches 250 thousand km. On the cold engine "Dieselit", the characteristic dictum comes from the injectors. In general, the engine is unpretentious and reliable. Constructive disadvantages include insufficient piston cooling, which leads to bulk, knocking of pistons and fingers in skirts.
4) G4KE - 2,4 l KIA Sportage gasoline engine, which gives 175 liters. from. Power. The lubricant system accommodates 4.6 liters of oil. This is a prototype of the MITSUBISHI 4B12 power unit with an aluminum cylinder block. The advantages of G4KE include a proven design, a good power supply and strength.
5) 2.0 CRDI - used at Kia Sport III generation, gives 136 or 184 liters. from. Completed by the direct injection system. Raughty low flow Fuel. During solid runs, controllers are delivered, sensors, fuel system.
Fourth generation
The new Kia Sportage is manufactured since 2016. It is equipped with 3 gasoline and 3 diesel engines. Among them are improved units from previous generations. For example, the same G4KE is 185 liters. from. The Korean manufacturer has not refused and from 1.7 CRDI with a capacity of 115 liters. from. This is a record holder in terms of efficiency: consumes up to 5 liters per 100 km of a mixed cycle.
G4fd appeared in the bus line - 1.6 GDI. Gas engine GAMMA rules can work in a pair with mechanics or machine gun. Thanks to the direct fuel injection, it was possible to achieve the best responsiveness at low revs. And the increased compression and optimization of gear ratios in the box had a positive effect on gasoline consumption.
How to increase the resource of the engine Kia Sportage?
To extend the life of the KIA Sportage power unit, you need to hold only two rules: properly operate the car and carry out competent maintenance, reducing the frequency of oil change to 7-10 thousand km. An increase in the resource is facilitated by the RVS-Master additive and the prophylactic, which is carried out by MF5. We will analyze individually the features of these products.
Additive in DVS - Repair and recovery, which restores conjugate pairs of friction from ferrous metals by increasing the tight layer of metal ceramics. The fine composition is not a classic oil additive, since it does not affect its physicochemical properties.
Due to the G4GC processing with the cast-iron cylinder block, it is possible to achieve an increase in compression, reducing the oil and fuel consumption, increasing the engine resource, incidence of noise and vibrations. The friction geomodifier forms a metal-ceramic layer on surfaces from ferrous metals, resistant to corrosion, oxidation, wear, and it simply cleans parts from aluminum and contaminants. Impact efficiency impact repair at Kia Sportage may differ depending on the design and technical status Motor. The adding to the additive is appropriate to combine with the planned something - the replacement of engine oil and other consumables.
MF5 - Additive for washing the oil system, which is used to clean the working surfaces from carbon black and wear products. The composition is safe for seals, gaskets. The frequency of its use depends on the nature of the KIA Sportage. Without additives, it is not necessary when you go to new oil, discovered an extraneous substance in the fusion working fluid Or purchased a used car, but not sure about the quality of its service. MF5 additive is useful for scheduled maintenance, as it has an integrated effect:
- Restores damaged cylinders.
- Disposals utilizes metal oxides.
- Restores the elasticity of seals.
- Generates a layer of metal ceramics on working surfaces.
MF5 should be applied before replacing the oil. Consider, unlike the RVS-Master, the flushing does not help if the troit motor, compression fell, there is wear of the friction surfaces. In such cases, it is necessary to fully diagnose and restore the power unit.
Drive, automatic transmission and MCPP KIA SPORTAGE
Mechanics Kia Sportage all generations are very reliable. On cars that are operating in sophisticated conditionsAt high loads, the characteristic howl, noise, hum. Often it is associated with wear gears. For their recovery, the additive is suitable or. But it is necessary to use it before the debris and chips fall into the lubricant system. This will avoid overhaul, Extends the transmission resource, make switching more smooth and easy, eliminating an unpleasant crunch, knock.
Similar additives are used to handle the bridge, dispensing to eliminate howl, hum, improve the operation of the full drive. Most of the 4WD Kia Sportage breakdowns are associated with the overheating of the clutch, oil leaks, a breakdown of the pump, whose filters are clogged with mud. Therefore, the crossover owners need to closely monitor the oil level and tightness of the system, to propagate the additive to the oil to disperse and the bridge to the oil.
Concerning automatic transmissionHer breakdowns are manifested by jogs and pinks, slippets when switching. As practice shows, this may occur with any run, which will lead to the need for expensive repair or full replacement of the box. For recovery and impact repair, we recommend. The additive compensates for wear bearing, gear wheels and other parts, makes switching easy and smooth. It will be useful for any of the automatic transmission: re4R01A, F4A42, F4A51, A6GF1.
