Daewoo NexiaEquipped with a gasoline engine is manufactured since 1996. First Daewoo Nexia. Published with an 8-valve engine of 1.5 liters, and then a 16-valve 1.6 liter. The DOHC type F16MF engine issues 109 liters. from. Power. And the A15SMS motor is designed for 86 liters. from. And, in addition to Nexia, installed on Chevrolet Lanos.
A mechanical five-speed gearbox works in a pair with power units, the Korean versions with automatic transmission, four-stage mechanical boxes, are less common. Concerning power plants Daewoo Nexia, preference is worth paying a 1.6-liter motor, which is considered more reliable. On models with 1.5-liter DVS is often highlighted fault Check. Engine, which is often associated with a banal malfunction of sensors, damage to the contacts, and not problems in the aggregate itself.
Owners of dorestayling cars complain about the leaking gasket GBC.. A similar problem was found on Opel Cadet. It is associated with the wrong tightening valve coverwhich was subsequently replaced by a manufacturer on a plastic analogue. Oil leakage leads to work in a lack of lubricant, oil often falls into candleysWhat provokes uneven operation. All this is fraught with overheating, accelerated wear of the distribution and crankshaft, cylinder-piston group. Gradually will decrease the power will increase the flow rate, a characteristic knock will appear. To avoid negative consequences, you need to fix the factory defect valve cover. You should also take care of timely dEU service Nexia.
Motors Features Daewoo Nexia

Construction: What is noteworthy? |
||
|---|---|---|
|
8 valves; an analogue of C16NZ from Opel, but has other diameters of cylinders, which is distinguished by the configuration of the pistons and oil pump, the other GBC layout; It goes 200-250 thousand km. |

|
16 valves; 85 l. from.; 2 camshafts and an ignition emble; Little fuel consumption compared to G15MF. |
||
|
89 liters from.; compliance with Euro-3 standards; fuel system Built just like on Chevrolet Lanos. |

109 liters from.; Structurally and externally similar to x14xe; There are hydraulic components, recycling exhaust gases; EGR valve; Among the shortcomings, a small resource of lambda probe and problems with the functioning of the thermostat. |
For regulatory, G15MF engines are 75 liters. p., A15MF is 90 liters. p., F16D3 is 109 liters. from. It will take 3.8 liters of oil. To extend the Daewoo Nexia motor resource, you can use. This will allow you to restore worn surfaces, which are based on ferrous metals. The details are formed a dense layer of metal ceramics, the compression is normalized, the level of noise and vibration is reduced, fuel consumption and oil drops. Daewoo Nexia consumes about 10 liters of gasoline per 100 km path in the city cycle. With the wear of the power unit and the problems of the fuel system, this indicator increases by 2-3 liters. And due to the complex processing of the repair and reducing composition it is possible to normalize it.
If you are not sure as fuel on gas station, use. It will increase octane number 3-5 units and will save up to 10% fuel. Fuelexx removes water from fuel, optimizes combustion processes, contributes to the cutting of the piston rings.
The combustion catalyst is very useful for Daewoo Nexia with a 1.6-liter engine by 1.6 liters: due to low quality russian gasoline The EGR valve often fails in the car - the recirculation system is locked.
We understand with Daewoo Nexia box
The most common five-speed mechanical box - Development prototype from Opel. Oil in it should be changed every 80-90 thousand km, although it does not mention this procedure, the car owners and mechanics are advised to adhere to such rules.
Over time, the seal of the main transfer is beginning to flow, the smooth switch is often disturbed on the used cars. To make the inclusion of gears easier, change the drives of the drive and sleeve (sold in the kit). Additionally, the box can be treated with friction geomodifier. This will restore geometer geometry, reduce the noise level and the amount of vibrations, which is useful for transmissions of new and used Daewoo Nexia. The RVS-Master checkpoint compensates for wear and forms protective layerrather than a temporary film, unlike competitors, which allows you to independently repair without parsing and get rid of the roast.
Engine Nexia 8 valves The volume of 1.5 liters was one of the most popular on Daewoo Nexia recent years of release. Today with this motor quite a lot of cars on secondary market. 80 hp aggregate (A15 SMS), this is a gasoline atmospheric with a distributed multipoint fuel injection with a ignition coil, which replaced the G15 MF motor of 1.5 liters developing 75 hp With an unreliable rubber. 
Engine device Nexia 8 valves
Nexia engine gasoline, four-stroke, four-cylinder, in-line, eight-block, with the upper arrangement of the camshaft. Location B. motor compartment transverse. Cylinder Operation: 1-3-4-2, countdown - from pulley auxiliary aggregates. The power system is a phased distributed fuel injection (Euro-3 toxicity standards). Motor has a cast iron block of cylinders.
Engine with gearbox and clutch form force aggregate - Single block, fixed in the engine compartment on three elastic rubber-metal supports. The right support is attached to the bracket located on the front wall of the cylinder block, and the left and rear - to the gearbox.
Head block of cylinder engine Nexia 8 valves
Nexia 8 valves of aluminum alloy cylinder block head, total for all four cylinders. The head is centered on the block with two sleeves and is attached to ten bolts. Sealing gasket is installed between the block and head of the cylinder block.
On the opposite sides of the cylinder head, the windows of intake and outlet channels are located. The saddles and guide sleeves of the valves are pressed into the cylinder head. The valve closes under the action of one spring. It rests on the lower end to the washer, and the top is on the plate held by two crumbs. Collapshedral creaks have a shape of a truncated cone, and on their inner surface, puzzles are made in the valve rods. Prolve valves in motion camshaft. Camshaft - The cast iron, rotates on five supports (bearings) in the aluminum housing of bearings, which is attached to the top of the cylinder head.
Driver motor motor Nexia 8 valves
The drive of the camshaft of the 8-valve engine of non-zeys is carried out by a gear strap from crankshaft. The valves are powered by camshafts through the pressure levers, which are led by one shoulder on the gap hydrocomators, and the other shoulders through the guide washers are on the valve rods.
The engine has hydrocompensatorswhich are self-regulating piping leverage supports. Under the action of oil filling the inner cavity of the compensator, the compensator plunger selects the gap in the valve drive. The use of hydrocomathers in the valve drive reduces the noise of the gas distribution mechanism, and also excludes its maintenance.
In the event of a cliff of the valve belt, Gnet! In addition to other features, it can be noted that the timing belt rotates the pump (water pump). Replacing the belt is carried out every 60,000 kilometers, the pump must be changed once every 120 thousand mileage kilometers. Note that on the old 8-valve motor with a capacity of 75 hp The timing belt is not changing every 40 thousand kilometers.

Daewoo Nexia car in Russia at one time acquired an extraordinary popularity, but these cars can be constantly seeing on the roads of our country.
This brand has long been selling in the territory Russian Federation, and so far "Nexia" is good in demand.
A little from the history of Daewoo Nexia
The progenitor of the Daewoo Nexia car has become many well-known Opel Cadet E, which was produced by the German company from 1984 to 1991. At first, "Nexia" was produced in Korea under the name Daewoo Racer, and her release continued until 1995. For a while, the large-sized assembly of "Nexia" was carried out in the Red Asca of the Rostov region, but in the 1998th, the release of the car was discontinued.
The main production of Daewoo Nexia has begun in Uzbekistan in Asaka, the first cars from the conveyor went in 1996. Almost immediately, the car began to be exported to Russia, and in 2008, Nexia has undergone a small restyling:
- new headlights appeared;
- changed bumper;
- became another trunk lid;
- released rear lights.
There were still very minor external changes, but in general the car remained recognizable and differed from dorestayling "Nexia" a little.
The first Uzbek "Nexia" went in two grades:
- GL - basic version;
- GLE - option "Lux".
Basic equipment was very simple, sometimes there was not even an amplifier of the steering wheel. In the GLE version, the car was equipped with additional options:
- power windows;
- hydraulic steering amplifier;
- air conditioning;
- fog lights;
- electrical antenna.
At first B. model row Daewoo Nexia power units have been listed one only gas engine 1.5 l. The motor had a power of 75 liters. p., Inline location of four cylinders.
Engine G15MF - 8 valve, one inlet and exhaust valve On the cylinder, in many ways it is very similar to the OPELEV C16NZ. Despite the apparent external similarity, opel motors And Nexia have significant differences, and on the Motor G15MF:
- another diameter of cylinders, respectively, the pistons have a completely different configuration and sizes;
- on the crankshaft, another tide was made under the Oil pump drive;
- another configuration of the drive is the oil pump itself;
- in the head of the cylinder block, instead of the plug, a metal fitting is pressed under the pipe of the cooling system, besides, the GBC is somewhat different combustion chambers.
There are still a number of design differences that do not allow you to install the Details from the C16NZ motor G15MF engine. In particular, "Nexia" puts its own distributor, and it does not suit any "Opel".
Engine Daewoo Nexia 1.5 has the following characteristics:
- type of fuel system - distributed injection;
- location by car - transverse;
- volume - 1498 cm³;
- number of valves - 8;
- cylinder diameter - 76.5 mm;
- piston stroke - 81.5 mm;
- the diameter of the native crankshaft necks is 55 mm;
- the diameter of the connecting coil - 43 mm.
Despite the fact that the engine Daewoo Nexia 1.5 has 8 valves, the car can develop quite a decent speed (up to 175 km / h) and accelerate to 100 kilometers in 12.5 seconds. In urban mode, fuel consumption with a G15MF motor is 9.3 liters per 100 kilometers, on the highway outside the city - 7 l / 100 km, with a dynamic driving, gasoline consumption increases. 
The 8-valve engine Nexia is very reliable, and if it takes off properly (do not overheat, do not overload, it can change the engine oil in time), then the motor can pass without overhaul More than 200 thousand kilometers. It should be noted that some car owners did not spare the engine by car at all:
- lily in it is the cheapest surrogate oil;
- forgot to change the oil on time;
- did not check the oil level in the crankcase.
If such a "killed" engine, remove the lid of the oil-wave neck, you can immediately see the blackness on the camshaft, which is formed from poor-quality oil. However, even such motors miraculously "survived", and this suggests how reliable they are.
In 2002, some changes were made in Daewoo Nexia, although they are difficult to call them restyling. But the main novelty of this year is the appearance in the line of power units of the new 16-valve motor A15MF transmission of 1.5 liters and with a capacity of 85 liters. from.
The main difference of this motor from the 8-valve is a completely different head of the cylinder block, in which two camshafts are installed. In the power unit there is no longer a traver, the ignition manages the electronic unit. The diameter of the cylinders remained the same, but the pistons were changed - four valve pensions appeared on the bottom. Honestly, the grooves on the pistons do not play a special role - when the timing belt is broken, the valve bends. The 8-valve internal engine G15MF in this regard remains in the winnings, the trimmed belt of the gas distribution mechanism on it does not cause damage to the engine.
As for the crankshaft, he remained the same, the interchangeability of the Chanks A15MF and G15MF is complete. Also, the changes did not touch the oil pump, the engine pallet, flywheel and clutch. In connection with the installation of a more advanced ignition system on "Nexia" with a 16-valve motor, fuel consumption slightly decreased:
- in the city cycle - 9.3 l / 100 km;
- on the highway outside the city - 6.5 l / 100 km.
New engines 2008
In 2008, in addition external changes In the body in Daewoo Nexia, the engine ruler was updated:
- instead of the Moral Outdated Motor G15MF, the A15SMS was installed. In this power unit, a fuel system was applied Chevrolet Lanos., the engine began to meet EURO-3 ecology standards;
- on shift 16. valve engine A15MF 1.5 liters came the new F16D3 model, 1.6 liters.
The A15SMS motor has become "stronger" its predecessor, its capacity has increased to 89 liters. s., But he has one "fat" minus - due to the fact that the GBC has a new engine from "Lanos", when the timing belt breaks, now the valves are "found" with pistons.
On the car Daewoo Nexia since 2008, a new 16-valve F16D3 motor is established, which meets the ecological requirements of Euro-3 and 4, first this engine appeared on Chevrolet Lacetti.. Also, the F16D3 engine was equipped with a model Chevrolet Cruze.The prototype of the motor was the pilot X14XE power unit. Although the volumes of these motors are different, structurally and externally among themselves are very similar. Both engines have:
- belt drive gas distribution mechanism;
- hydraulic compensators;
- two camshafts;
- the system recirculation system of exhaust gases.
F16D3 gasoline engine has the following specifications:
- quantity / location of cylinders - four, inline;
- volume - 1598 cm³;
- power - 109 hp;
- fuel system - distributed injection;
- the degree of compression in the cylinders - 9.5;
- cylinder diameter - 79 mm;
- piston stroke - 81.5 mm.
To reduce the toxicity of exhaust gases to this motor, the EGR valve is installed, but from the Russian gasoline, the recirculation system is often clogged, and many car owners this valve is delay. The F16D3 engine is not just similar to X14XE, he also adopted all the diseases from the Opel Power Unit:
- the fast failure of the lambda probe (also due to poor-quality fuels);
- leak oils from the valve cover;
- problems with a thermostat that opens before you need.
The flow did not give big trouble if the oil had not been crushed into the candlestones. Penetrated into the well, the oil hits the electrodes of the spark plug electrodes, and the internal combustion center begins to trim. But on the engine of Daewoo Nexia 1.6 rarely when the oil is consumed through the piston rings, in this plan the motor is reliable.
Like any other car, Daewoo Nexia needs maintenance, and in the engine it is necessary to change engine oil according to the established regulation. The frequency of oil replacement on the "Nexia" motors is generally the same as on other models passenger cars - every 10 thousand km mileage. If the operating conditions are heavy (high loads, work in hot climate), oil is recommended to change after 5 thousand km.
Requirements for engine oils on Nexia Standard, some special conditions are not presented to them. To make the oil not burning, and did not form black on the details inside the engine, it should be high-quality, with good additives. Mineral oil It is not recommended to pour into engines, it is better to use "synthetics" or "semi-synthetic".
For winter engine oil, viscosity should be lower, according to the SAE classification for frosty winters, it is good to use the brands 5W30, 0W30, 5W40, 0W40. On a dense motor oil When starting in the frost, there is an intensive wear of engine parts, the engine is reduced, so all-season oil in winter should not be used.
It is recommended to pour almost any oil of well-known global manufacturers, the main thing is that it is not a fake. Often in Motors Daewoo Nexia Applies oil companies:
- Castrol;
- Mobil;
- Chevron;
It has long been proven that fake oil It is the cause of nagar formation, reducing the engine resource. The secret here is very simple - there are no those in the fake quality additiveswhich have the necessary lubricant properties, reduce friction between driving items.
If "Synthetics" for a car owner is too expensive, you can replace it semi-synthetic oil, big trouble will not happen. But when replacing synthetic oil On the "semi-synthetic" it is necessary to thoroughly rinse the oil system before pouring a new oil into the engine Daewoo Nexia.
The f16d3 engine for nexia began to set after 2008. Nexia with this engine has become very dynamic, because the motor has a volume of 1.6 and 16 valves. Daewoo this engine is called DOHC.
Initially, the engine was marked F14D3 with a volume of only 1.4 liters. After modernization at the GM plant, the "F16D3" motor was born and its subsequent modifications. In turn, F14D3 is the continuation of the Z16XE Opell Motor (2001), everything is interchangeably with this engine. The next and last modification of the engine F16D4 - the phase regulators were added to it and forced, it has a volume of 125 horse power against 109 forces on the predecessor.
Technical characteristics of the engine F16D3 from Daewoo Nexia
Approximate engine resource 220 - 250 thousand kilometers. In fact, this motor is counted for million painters, it all depends on the maintenance of the motor, as well as on the conditions of its work.
It is worth noting that when the timing belt breaks on this motor will fit the valve. During the cliff of the valve, encounter pistons and the higher the crankshaft turnover at this moment, the more damage it will be.
Engine is installed - Chevrolet Cruze, Daewoo Lanos, Chevrolet Lanos, Daewoo Nexia, Chevrolet Aveo, Chevrolet Lacetti, Daewoo Lacetti., ZAZ CHANCE, CHEVROLET NEXIA. The capacity of 109 horsepower is very sharply accelerates such a light car as Daewoo Nexia.
Typical engine malfunctions F16D3 on Nexia
The F16D3 engine is equipped with an EGR valve - exhaust gas recycling system. The spent gases re-enter the intake tract and trample. This was done to reduce the norms of toxicity, but because of this, the oil loses its properties faster and forms a nagar on the valves. The engine is essentially breathing with its own exhaust. For Nexia, we wrote how to drown out the USB valve, but this instruction It will help to other owners of this engine. Also, this valve quickly clogs itself from poor-quality fuel and clogs the engine, so we recommend it to turn off.
Also typical problem This motor is to flow oils from under the valve roof (cylinder head cover). We also have already written how to eliminate leaks of oils from under the valve cover on nonsense.
With a lack of oil, the valve and hydrocompensators begin to conjure. If you give a load when there is no oil, the engine can be sent to the garbage.
Engine tuning F16D3
We devoted a whole section about tuning on Nexia. To increase the number of horsepower, you need to flash the engine, but the firmware gives 5-8 hp from the strength. To get a significant increase, you need to put the spider 4-2-1. New edition Increases up to 125 horsepower.
The simplest I. effective method Improve the dynamics of the car and reduce the flow, it is to remove the catalyst and change the release. The catalyst and standard release strongly stroke the motor and do not give it to work in normal power. This is the most accessible type of tuning.
From this car never demanded a lot. Nexia bribed low price and good reliability. It must be said that the first generation of Ksyusha (so in the people they called this car) more or less justified the confidence. His first 100 thousand cars were leaning, as a rule, without any problems. In mid-2008, the plant presented the updated model - Nexia N150. Now, after almost 3 years, we decided to summarize all sores and problem places updated model ...
Engines
Nexia buyers can choose from two engines. The company is a 1.5-liter eight-point (80 hp) made up a relatively modern 16-valve motor volume of 1.6 liters and with a capacity of 109 hp Both are consistent with EURO 3 standards, and do not differ acne. This is especially true of the 1.5-liter unit.
Motors - Oil. However, it largely depends on the operating conditions and driving manners. Consumption of 300 g for each thousand km is considered normal for them. Under our conditions of operation, between planned visits on the oil level service is better not to forget. By the way about maintenance. In 2010, a new regulation was developed maintenance. Previously, the so-called zero, it was necessary to pass over a thousand km of mileage, now the interservice interval rose to two thousand. Visits to scheduled maintenance is prescribed to apply with a frequency of 10 thousand km of run or once a year, and not half a year, as it was before. Violation of service rules leads to a loss of a guarantee, in fact, as in any automaker.
Note that according to the new regulations, the warranty on Nexia is 3 years or 100 thousand km of run.
Maintenance is registered scrupulously and quite volume. So, T-3 (20 thousand km of run) involves the replacement of oil, air and fuel filters, spark plugs. Along with the original components, a visit to the service will cost somewhere in 8 thousand rubles. (work - up to 2 thousand rubles., Details are about 6 thousand rubles.). Dear, of course, under the hood you will be updated a lot.
The timing set on both engines changes every 40 thousand km of run (TO-5). On an eight point, a tensioner roller comes with a belt. The design of the timing of a 1.6-liter engine with 16 valves is more complicated. In addition to the belt, it includes a roller of an automatic tensioner and a supporting roller.
"Potion" of a 1,5-liter motor - parable in pags! Oil regularly wakes up from under the valve cover and cylinder gaskets. Replacing the gasket helps at best a couple of thousand km. One way to eliminate oil "excess" is the installation of the valve cover from Chevrolet Lanos. The other is the engine washing on each then. The procedure will cost 300 rubles, but under the hood will always be clean.
Transmission
It is on Nexia in a new body a clutch for some reason became thoughtful. To turn on something without any problems, you need to wait for a 3-second pause. Agree, in the conditions of urban movement is not the most pleasant feature.
There was a period when the transmission in the plant was poured pretty liquid oil. It warmed very quickly, losing viscosity. The first symptom is the knocks in the CP with a sharp work of the clutch pedal. Experts recommended not to wait for the second and third symptoms, but simply pour in the box a proven semi-synthetic age.
Today the plant corrected: the SAEW80W-90 specification liquid was pulled into the gear box, according to the degree of viscosity, more appropriate operation in summer conditions. In the "Car Operation Manual", the manufacturer recommends that in winter conditions use less viscous oil SAEW75W-90 specification.
As for the frequency of oil replacement in MCP, it is 120 thousand km. The clutch is in order of 80 thousand km. About 50-60 thousand km walk shrus.
Electrical equipment
At first, a lot of complaints caused a light bulb Check Enginewhich suddenly light up and did not go out, no matter what tricks. Immediately reassure - as a rule, nothing criminal, the reason is the glitch of the controller. The controller simply "did not see" the sensor position of the crankshaft of the engine (error P13360). It was possible to cure it only at the dealer, and often the replacement of the controller itself. By the beginning of 2009, the plant coped with the problem. If today you will distort Check Engine, most likely, the fault of poor-quality gasoline.
Relays, sensors and other electrical appliances are made in various corners of our planet, from Kaluga and Pskov to India. Alas, neither the quality, neither repairability at first they could not boast. Thus, a combination of devices made in India suffered from "hanging" the arrows. Phantom malfunction sometimes appeared on new Nexia.And on the car, running not one tet of thousand km. The essence of the case did not change: wait for the "panel" accounted for at least two or three months. In 2009, there were a critical mass on Indian devices, and at the present requirement of the manufacturer, the Indians finally took up the case. As a result, by 2010, the cases of "hanging" became single.
Chassis and body
Not really tolerant to road collective ball supports and shock absorbers. Active riding off-road will shorten the service life of their service almost twice - somewhere up to 60 thousand km of mileage.
Front brake pads There are about 60 thousand km, discs change with each second replacement pads. Rear drum pads are kept up to 120 thousand km.
Increasingly, dealer technical center specialists pay attention to quality deterioration. paint coating. Today, cars with "shaggy", non-crushes and varnights in the order of things. But this problem is not so much Nexia, how many all automakers of this segment.
But the low quality sealing of the joints of body panels, alas, a feature of "Ksyusha". It happened that in heavy rain in the salon and the trunk was selected water. The same sinned glass seals.
In my opinion...
Editor:
This car does not take on the kettling of the heart, Nexia is often used exclusively as a means of movement or delivery. It is clear that the requirements for such a car purely pragmatic: efficiency, reliability, unpretentiousness. And although at first the model N150 did not really boast of reliability, it should be paid to the plant due - today Ksyusha confidently goes on the amendment.
