Malfunctions and repair of the engine Renault Logan 1.4

Renault Logan K7J 710 engine 1.4 liters. 75 hp It is the evolution of old engines EXJ development of the 80s. Constructively, the Dacia Logan engine has a strange and enough archaic design, it still uses the timing rocker and the strange oil pump drive system of the driving engine K7J 710 from the lower legitators of the 60s. Despite this, with proper running (turn no higher than 3-3.5 thousand / O, the speed is not higher than 130 km / h, during the first 1000 km), timely service, the motor is very reliable, the Logan's engine test in factory tests amounted to more than 400 thousand km, and how much does it go to practice? There are copies with even greater mileage, resource at height! The popularity of cars with this engine at taxi drivers is unnecessary confirmation.
The minuses of the engine K7J include high fuel consumption. Often at idle begin to float turns. On the engine Renault Logan 1.4 there are no hydrocompensators, so every 20-30 thousand km need to adjust the valve. The timing belt drive, when the belt is climbing, Logan's burns out of the valve, so as to protect yourself from this, once in 60 thousand km. It is necessary to change the belt. In addition, the crankshaft seal often flows, the motor itself is noisy and does not go anywhere on the track. There is a more powerful and surround version of this motor - K7m.When choosing a car with data, pay attention to the K7M.
Recommended: taxi drivers, the most calm drivers in the world, women.
Not recommended: youth, fans of aggressive driving style.

Dacific Engine Disadvantages / Renault Logan

Let's start not quite with a lack, but the problem of the question is: warming the engine and should it be warm? The instruction says, sat down, in practice, the oil becomes more viscous and worse fed to rubbing couples, it will not be superfluous to give a motor to work to an even idling.
We turn directly to malfunctions, often the owners face the unstable operation of the Renault Logan engine or it is completely stupid, the problem is most likely in the RCX (idle regulator), it was possible that the fuel pump filter grid was clogged or the fuel filter arrived, maybe DPKV (crankshaft position sensor) or coil ignition.
If it stalls on the go, and the motor is completely warm, look for air traffic jams in the cooling system.
Next fault - engine overheating Logan or vice versa, does not heat. The problem in the thermostat is most often. In case of overheating to reasons, you can add a water pump malfunction or zoom in the cooling or radiator channels. Perhaps you are too overloaded the motor, the nagar in the combustion chamber or high compression.
Third Type of faults: knock and noise in the engine Renault Logan, what is the reason? The cause can be valve that requires adjustment of gaps, an explicit metal sound occurs, the reason is solved by visiting the service and adjusting the valves. Indigenous and connecting rod bearings, pistons and piston fingers can knock. In all cases, you need to deliver a car to the service and solve the question as soon as possible, otherwise the consequences will hit the pocket.
Do you feel the vibration of the engine Renault Logan? Most often, the cause of the engine cushion is becoming the cause of the reasons, in addition to reasons, we will draw the crankshaft imbalance, various compression in the cylinders or weakened the crankshaft pulley.
Well, a popular problem, your engine Logan Troit, what to do what to sin, whom to blame ... Causes are simple, tritely poured bad gasoline or ignition coil, no? We look at high-voltage wires, candles, gas station.

Renault Logan Engine Tuning 1.4 K7J 710

The K7J engine was originally developed using obsolete technologies with an eye on a resource, the reliability and sports component were not considered in principle. In addition, after improving the engine, the main trump card is lost - reliability. At the same time, any dynamics are not purchased, a similar VAZ will be faster ... There is no tuning meaning. For observed continue ...consider several versions of tuning this engine:

Chip tuning, engine firmware Renault Logan 1.4

Tuning offices offer firmware with increasing power by integer 7-9 hp Naturally, the firmware of the atmospheric motor will not give anything and the whole increase will remain at the level of self-sustaining, but the fuel consumption will increase.
It is the opinion that if you remove the catalyst on Logan and flash, then the car will fly ... In vain spend time, there is no sense from it, the car does not go.

Compressor on Renault Logan 1.4

The easiest, fast and reliable way to establish a compressor, it is to buy ready-made whale. For the Logan Motor Whales is not so much in nature, but still there are offices ready to sell the finished set, one of the most famous such office, this is a popular (among tazovodes) St. Petersburg company car turbo, they can order a set based on PC-23-1 With a pressure of 0.5 bar, the standard motor will stand without refinement of piston and inflated in the region of 90-100 forces. A more productive PC-23rd with a pressure of 0.7 bar asks to reduce the degree of compression, we will reduce the setting of the thick gasket of the GBC or two pads, it may be necessary to revise / replacing the piston. For both compressors, more productive Volgo nozzles of Bosch 107 will be required, exhaust refinement and online configuration. If there is a budget in 1/4 of the car's cost, you can properly assemble a compressor based on Toyotovsky SC14 from Mark, but the list of additional parts stretches into several pages. Anyway, some other power you do not get.
Does the compressor of the engine Resource K7J ?? Of course it will reduce, but the tunnelovychikov is little worried))

Turbine on Renault Logan 1.4

We do as well as with the compressor, Bosch nozzles 107, the gasket of the GBC, the intercooler (from evolution, for example), exhaust on 51 mm pipe, pales, consumables, the IHI RHB3 turbine itself or the like. Now this pile of iron needs to be adjusted, for this you need to make friends with the ECU of January, it will not be easy, but realizable completely. At the output, this kit will be given + \\ - 100 hp

Purchase and installation of 1.6 liters. 16V

Ideal tuning 1.4 liter engine, buy a good, gently engaged in the engine K4m. And make SWAP. We avoid moving with supervision, loss of resource and regular repairs, after good Valilov))

Each unit, be it the engine, gearbox or steering power system requires constant lubricant control. And for each node there is a certain minimum and maximum limit of the amount of fuel oil, water, cooling or brake fluid.

Below will be considered separately each of the nodes and aggregates of the car Renault Logan.

How much oil is pouring into the engine Renault Logan

Since various types of engines were installed on Renault Logan cars, then filling volumes for each of them will be different:

1. For 1.6 and 1.4 8-valves - 3.3 liters
2. For 1.6 16-valves - 4.9 liters

How much oil is pouring to Renault Logan

Since the gearboxes on all vehicles did not differ, that is, they were the same as on 8, and on 16 valve motors, then the filling volumes will be identical.

For CTP CTP, the required level of transmission oil should be about 3.1 liters. Check the level of SHUP cannot be due to its absence. But there is another way - unscrew the plug of the fuel hole and the oil should be at the bottom edge. That is, pour above the level in this case is simply impossible - all excess flows through the bay hole.

How much toosol or antifreeze holds the cooling system by the engine

Behind the level of fluid in the cooling system must be monitored primarily! If Tososol leaves, and during this not to notice, you can override the engine with all the ensuing consequences. Therefore, you should not be lazy to openly open the hood and make sure the needy level of antifreeze in the expansion tank.

It must be between the minimum and maximum marks. You can clearly look at the approximate level of coolant in the photo below.

As for the entire system of cooling Renault Logan, it contains about 5.45 liters of coolant. Adjustment to produce only the recommended type of coolant for your car, as well as taking into account the already sprinkled liquid.

How many brake fluid in the system

In case of insufficient level of the brake fluid, braking efficiency may decrease, since the emergence of air is not excluded in the system. With a sharp press on the brake pedal (in cases with emergency braking), the fluid level in the tank drops sharply, and in the absence of the required volume of the vehicle wheel can not be blocked properly.

That is why the level should always be at the maximum mark.

How many gasoline in the fuel tank

Renault Logan gas tank accommodates 50 liters of fuel. When the lamp lights in the tank lights up, then the gasoline residue is about 6-7 liters.

The timeliness of changing the oil in the motor is the key to preserving the performance of the driving elements. The high-quality fluid is capable of preventing their premature wear and reduce the intensity of clogging of the lubricant contour of the unit with abrasive products from abrasion. Many car owners are interested in the question, what oil to fill?

Renault Logan cars are mostly equipped with 8-valve Renault motors: "K7M1.6" and "K7J1.4", as well as 16-valve - "K4M1.6". The latter are endowed with a slightly increased elimination. They also characterize better mixture formation. But the 8-valve "counterparts" boast weighing reliability, constructive simplicity and maintainability. However, the question of which oil pour into the engine into different versions of the model, experts answer that there is no principal difference.

With the standard operation, the Renault Logan motor resource can reach 400 thousand km.

So what kind of oil is to upload correctly? Here is a distinction for these aggregates in terms of volume fill in them engine oil:

• 1.6-liter 16-valve version (K4M) - 4.8 liters;
• 1,4-liter 8-valve variation (K7J) - 3.35 liters;
• 1,6-liter 8-valve version (K7J) - 3.4 liters.

And what oil to fill, if you do not change the filter? If the oil change is implied without changing the filter element, then these volumes should be reduced by 0.3 liters. It is recommended to replace the oil in a set with a filter, since this element (not characterized by a high cost) prevents lubricant wear caused by the appearance of abrasive particles in its medium - the products of the abrasion process.

What oil pour into an 1.4-liter engine? Replacing lubricant in Renault Logan motor in version 1.6 and 1.4 Recommended after every 15 thousand km of run. If the conditions for operation of the motor are very rigid, the oil change interval should be reduced by about 8 thousand km. Under such conditions, the following should be implied:

• renault Logan motor warm-up movement (especially relevant during operation with a bold lubricant before changing the season, when in winter or summer the outdoor temperature reaches critical values);
• aggressive acceleration dynamics accompanied by the exhaust load on the unit.

During control of the oil level in the crankcase, you can make a visual assessment of its condition and evaluate the degree of need for replacement. The liquid should not have black and give a quiet smell. If such factors are present, lubricant requires urgent replacement.

How to choose a suitable oil?

What kind of oil to pour best? The Renault brand is recommended to use Renault Logan Model Motors with ELF EVOLUTION SXR Lubrication with 5W40 or 5W30 indicators. Alternatively, the use of a synthetic substance suitable for the regulatory temperature criterion is possible:

• "5w40";
• "5W30";
• sometimes - "0W30 am".

When replacing the lubricant, we need to change the sealing ring on the plum plug and the filter element.

Specifications of these consumables are as follows:

• the cork sealing rings - 11026 5505r.
• the oil filtering element has 7700274177 or 8200768913 (both options are identical).

Algorithm for replacement actions in a 1.6-liter unit Logan

1. We unscrew the plug on the neck for the bay of lubricant.
2. Under the Motor Carter Renault Logan version 1.4 and, respectively, 1.6 we substitute a suitable container to collect "testing".
3. We remove the plastic protective plate of the crankcase (on the "8-valves" can not dismantle the protection, because it has a technological cutout for a drain plug).
4. We unscrew the drain plug on the pallet (the key of the square profile on "9").
5. We are waiting for the lubricant in full.
6. During this time, we unscrew the body of the old filter element (use the puller or other sweater means: a screwdriver, part of the emery sheet, etc.).
7. Before mounting a new element on Renault Logan, we smear its rubber ring "fresh" oil.
8. Install the filter, screwing it with its housing to the landing screw channel in the motor with an effort from hand.
9. Do not forget to install the sealing washer on the plug plug (consumable code - 1026 5505R).
10. Pour a new lubricant.
11. The position of the fluid level should be accommodated slightly below the MAX marker applied on the dipstick.
12. We spin the neck plug for the bay on the valve cover.
13. We start the motor and let it work for 5-6 minutes.
14. Wasting and expect 15-20 minutes.
15. Control the level - must be between MIN marks - "Max".
16. We inspect the location of the filter housing and drain plug and make sure there is no leaks.
17. To correctly monitor the quality of lubricant in the Renault Logan motor, you should mark the mileage at which this process is performed.

Now you have made a conclusion for yourself, what oil pour into the engine engine. Before the bay, it is recommended to rinse the system with lubricant from the same manufacturer. To do this, we fill in the Carter about 1 liter of oil, we bring the motor and give us to work for several minutes. Wasting and proceed with lubrication plum. Flushing is performed with an old filtering element, together with which contaminants will be removed when replaced.

In the engine there are many rubbing parts - pistons, rings, crankshaft. All of them require high-quality lubrication. With its absence there is a huge development. The most common problem is jackets in the cylinders. Therefore, it is so important to monitor the oil level and produce a replacement on time. In today's article, we will look at how it is done by car Renault Logan, the engine can be replaced in the engine.

Resource

The French manufacturer claims that this operation should be made every 15 thousand kilometers. But in dusty and difficult conditions, this figure should be shorted.

We also note that the optimal solution will be the replacement of Renault Logan oil on motorcycles. The interval is 350 hours. But it is worth noting that not everyone in the car has an on-board computer, which will read this data. Therefore, the optimal option is to replace the oil "Renault Logan" every 10 thousand kilometers.

Signs

Also, the lubricant state can be identified visually. Turning to the probe, pay attention to the shade and consistency of the fluid. If she is thick and acquired black, it means that it requires an urgent replacement. Another bad feature is the existence of Gary's smell on such a dipstick. This suggests that the car was operated in difficult conditions.

What pouring?

So, what oil is to fill in the "Renault Logan" engine? The manufacturer recommends using the product from the company "Elf". This is a series of "Evolution" and "Compatent" products. As for viscosity, it can be different.

The most liquid recommended lubricant has a 5W30 parameter. The most thick - 15W50 according to the international classification API. But it is worth noting that viscosity depends on the climate in which the car will be used. The colder, the higher the parameter. As practice has shown, optimal viscosity for medium latitudes in Russia - 15W40. Such oil does not lose its characteristics at temperatures from -20 to +30 or more degrees Celsius. You should also purchase a new oil filter on Renault Logan. Its price ranges from 150 to 600 rubles. It is better to acquire the original ("Fram" or "Mann").

Instruments

To replace oil in the Renault Logan engine, it is successful, we will need the following tools and devices:

• Square to 8.
• Filter puller.

We also need a container for draining old oil. Its volume should be at least four liters. Such a container can be made from the old canister - we carefully cut the sidewall and put it on the engine. You can use other containers, such as a pelvis or plastic bucket. But these devices are suitable only when using a pit or lift. Otherwise, such a container does not fit the engine even when using the jack.

Getting to work

So, we drive the car to the pit or put it on a flat section. The replacement of oil "Renault Logan" is produced "on the cold". Give the engine for 10-15 minutes so that it is cooled. After that, you can safely start work. Armed with rubber gloves and a square key on 8, we close to the engine's pallet. Please note that it can be closed with metal protection. It is not necessary to remove it. It is enough to find a rubber plug that will open access to the taste. Through this hole we will insert a tool for opening a plug. If it is dirty, we clean her soft rag. Next, install strictly under the hole to the canister or any other empty container. After that, we finally unscrew the cork. Make sure that it does not fall into the canister with butter. Nothing critical with her will not happen, but you will have to be pretty looking for her on the bottom (the exhaust oil is unlikely to be transparent).

Further we are waiting until all the oil is completely soles from the motor. If the replacement is made in winter, it is desirable to warm up the car and carefully unscrew the cork in order to not get a burn. Otherwise, viscous oil will merge very long. Typically, this process is given 10-15 minutes. To accelerate the process, we unscrew the cover of the filler neck (so that a vacuum is not formed in the system).

About traffic jam

While the oil merges into the container, we examine the condition of the plug itself. It has a metal rubberwiched washer that provides seal. If this element cracked or lost elasticity, it should be replaced with a new one. Otherwise, the oil will be frozen. Yes, for 10 thousand, it may not be poured and a glass of liquid. But even with the slightest flocks on the pallet, the dirt and road dust will stick.

About filter

Along with the oil you need to replace the filter. Where is he located? The element is located near the exhaust manifold and has a cylindrical shape. But it is unlikely to take it with your hands. To do this, use a special puller.

This tool gently wars the edges of the filter and unscrew it without damage. If there is no such puller, you can use a more barbaric way - to push the filter with a slotted screwdriver. Thus, we will have a lever. But it is worth noting that when the filter is damaged, the oil is released - at least 200 milliliters. Therefore, it is necessary to take care of buying a puller. It is universal and suited on Renault Logan. Price - from 300 rubles per unit.

It is necessary to get a filter to the outside quickly and gently so that the oil does not break down from the central hole. The element is unscrewed counterclockwise.

Useful Tip: When installing a new filter, apply a pair of oil drops on the sealing ring. And if the brand and viscosity of the new oil corresponds to the old, you can simply press both filters the end part to each other. So on the rubber band there will be a uniform oil film.

Filter installation is better to produce without tools. He twists his hands with effort. It is not worth tightly pressing it to the surface, otherwise the gum is simply squeezed (or there will be difficulties with further dismantling). Spin until you feel resistance.

What further?

Now it remains only to pour new oil into the engine. To completely clean the system from the old lubricant, you need to shed a little new. 100-200 milliliters are enough. We fill this volume into the engine and go down to the pallet. You will see how black liquid flows out of the hole (although it would seem, the oil is pure as a tear). So we completely remove old oil particles. Now we twist the cork and the oil in full. For convenience, use a plastic watering can (better without a grid, but clean).

We start the engine and warm it up to operating temperatures. After some time, we get the dipstick and look at its level. If he fell, pour oil again. Make sure that the level is average (between "MAX" and "Min"). The topping is a mandatory operation that needs to be produced when oil replaced. "Where is it going?" - you ask. Everything is simple: in the filter there is a bypass valve, which is closed on a non-working motor. As soon as we started the engine, some oil will go to the filter itself. The level will thus decrease.

After replacement, make a mark in a notebook indicating the date and mileage of the car. So you will know exactly how much the car is left to the nearest then.

How much to pour?

It all depends on the motor. If it is an 8-valve 1.4 or 1.6, then 3.4 liters poured. On the 16-valve motor - about 4.8. If it is the replacement of oil in the gearbox "Renault Logan", the volume is 3.1 liters. This is a parameter for the classic 5mcpp. But also put on these cars and "Avtomat". In this case, the replacement of oil in the gearbox "Renault Logan" will require at least 4 liters of ATP fluid. But it will be more expensive than ordinary transmission.

In the power steering wheel "Renault Logan"

The operation consists of several stages:

Conclusion

As you can see, everything is very simple. Regardless which the new "Renault Logan" has a technical characteristics and how much it is equipped with "dopami", all maintenance operations can be made with their own hands.
