Lacetti engine. Timing Belt for Chevrolet Lacetti Basic Gasoline Engine

The F16D3 automobile engine, the serial production of which was launched in 2004, was developed as a replacement for the F14D3 engine (2001 - 2008).

An analogue for these power units was the well-known power unit of the Ecotec family - Z16XE, created by the laboratory of Lotus Cars (Great Britain). It was installed on various Opel vehicles (Vectra, Astra, Meriva, Zafira) from 1995 to 2006.

In 2007, the F16D3 engine was discontinued, but its story did not end there. Chevrolet, which is an economically independent division of the American concern General Motors, in 2008 released new engines - F16D4 and F18D4, the production of which continues to this day. In practice, these power units are a modernized F16D3 engine.

Description

All three power units of this series (F18D4, etc.) are of the same type and are a four-cylinder four-stroke internal combustion engine with an in-line arrangement of cylinders.

Its cylinder block is cast from ductile iron, and the cylinders are bored directly into its body. The cylinder head is made of aluminum alloy and provides cross-scavenging of the cylinders.

The difference between the power units of the Ecotec D family, namely, they are the prototype of the engines in question, is the presence of 4 spark plug valves located in the center of each cylinder. That is why they use a 16-valve gas distribution mechanism (DOHC 16V) with two overhead camshafts, which is driven by a toothed belt.

The motors are equipped with electronic control systems:

• distributed fuel injection;
• ignition.

The engines also have the same type of lubrication and cooling systems. Forced cooling is carried out in a closed circuit.

The combined lubrication system is organized in such a way that engine oil is supplied to the friction pairs by spraying or under pressure (through oil channels made in the walls of the cylinder block and its head).

A distinctive feature of the power units is also a high degree of unification at the level of parts, a large number of which are interchangeable not only within the family, but also with the Opel Z16XE and Z16XER engines.

At the same time, there are significant differences in the design of engines, which predetermines a number of individual technical characteristics of each of them.

Modifications

• Features of the base motor F16 D3

The F14D3 engine was distinguished by its simplicity and reliability in operation. However, it had a number of drawbacks that negatively affected the stability of operation, for example: the use of the CVCP (Continuonus Variable Camshaft phasing) system in the gas distribution mechanism; application of an electronic control system for exhaust gas recirculation (EGR); use of hydraulic valve lifters.

Because of these shortcomings, the F16D3 engines were characterized by:

1. uncertain start;
2. unstable idling;
3. increased consumption of engine oil.

• Differences in the design of the power unit F16D4

When creating the F16D4 motor, the developers managed to get rid of the shortcomings characteristic of the base F16 D3.

So the F16D4 engine was equipped with a new VVT (Variable Valve Timing) variable valve timing system; He also received a system for changing the length of the intake pipes and got rid of the exhaust gas recirculation (EGR) system. In addition, valve lifters were replaced with calibrated cups.

As a result of the modernization, it was possible to obtain a more powerful and reliable engine.

• The F18D4 engine differs from the F16D4 engine in an increased cylinder capacity and, as a result, more power and traction. In its manufacture, the same design solutions were used as in the F16D4 motor.

In addition, it was possible to double the resource of the timing belt drive belt. Valve parts are made of chromium-silicon (inlet valve and exhaust stem) and chromium-manganese-nickel (exhaust valve head) alloys.

Maintenance

Operation of Chevrolet Aveo (F16D3), Chevrolet Cruze (F16D4 and F18D4) engines and other vehicles is carried out in accordance with the manufacturer's requirements for regular maintenance. carried out every 15 thousand km.

They include:

For engines installed on the Chevrolet Cruze (F18D4), replacement:

1. oil and fuel filters are produced no later than after 15,000 km of run. Used Chevrolet Cruze engine oil also requires replacement after 15 thousand km;
2. spark plugs are performed after 60,000 km of the distance traveled;
3. the drive belt and rollers of the gas distribution mechanism are carried out no later than after 150 thousand kilometers. At the same time, after 100 thousand km, its condition must be checked and, at the slightest suspicion, changed. If during the trip the belt breaks, then costly repairs cannot be avoided (valve bends);
4. it is advisable to carry out an air filter after every 50,000 km traveled;
5. The manufacturer recommends that the coolant be carried out once every 5 years or no later than 240 thousand km of the distance traveled.

In the engines of Chevrolet Aveo, Daewoo Lanos and other cars, replacement:

• engine oil is carried out every 15 thousand km of the distance traveled. It is also necessary to replace the oil, air and fuel filters;
• spark plugs must be carried out after 45 thousand kilometers;
• the timing belt and rollers are performed every 60 thousand km in order to avoid valve breakdown;
• coolant is recommended to do once every two years.

In the Chevrolet Cruze engine (F18D4, etc.), during routine maintenance, they change:

1. engine oil, gasoline and fuel filters - every 15 thousand km;
2. spark plugs - after 60,000 km of the distance traveled;
3. timing belt and rollers - after 100 ... 150,000 km of run. If the belt breaks while the valve is moving, it bends;
4. coolant - after 240,000 km or 5 years of operation (depending on which event comes first);
5. air filter - no later than after 50,000 km.

• Consumables for Chevrolet Lanos engines and engines of other cars manufactured by General Motors

The American concern General Motors, along with motors and cars, is engaged in the production of auto chemical goods. The concern manufactures these products in strict accordance with the requirements that apply to Chevrolet Cruze engines and their analogues.

That is why the technical documentation provides recommendations on the use of the original:

1. engine oil GM Dexos 2 Long Life 5W-30;
2. antifreeze GM Long Life Dex Cool.

GM Dexos 2 Long Life 5W-30 engine oil is an original product, the chemical composition of which includes special additives that extend oil life and contribute to a significant increase in the time interval between replacements.

This synthetic oil is designed for use in Chevrolet Cruze, Opel Mokka and other engines.

The original GM Long Life Dex Cool antifreeze superconcentrate has a unique chemical composition and has excellent anti-corrosion properties. The anti-corrosion agent, together with the antifreeze, increases the boiling point and, in addition, does not allow the coolant to freeze when exposed to low temperatures.

Also, the composition of antifreeze includes exuding inhibitors that provide an extended service life (up to 250 thousand km or 5 years of operation).

Antifreeze of this class is intended for use in Chevrolet Aveo, Daewoo Nexia, etc.

• Adjusting the valve clearances of the gas distribution mechanism

The engine of the Chevrolet Lacetti and other cars (F16D3) is equipped with hydraulic valve lifters, and therefore regular valve clearance adjustment is not required.
The Chevrolet Cruze engine uses calibrated cups instead of hydraulic lifters, with the help of which valve clearances are adjusted. This procedure is carried out during maintenance at the service station after every 100,000 km of run.

Faults

When using high-quality gasoline, regular maintenance, warming up the engine and gentle operation, the F16D3 engine, like the F16D4 and F18D4, runs from 200 to 250 thousand kilometers without problems.
However, car engines are not free from drawbacks.

These include:

• unstable idle speed on a cold engine;
• loss of traction;
• oil leaks through the valve cover gasket;
• overheating of the power unit.

In addition, the base engine F16D3 has a number of disadvantages that later power units of this series (F18D4) got rid of:

FAULTS	CAUSE	SOLUTIONS
valve sticking (motor loses power, stalls, troit, etc.).	Carbon build-up (small clearance between the valve and the guide sleeve, caused by the presence of carbon, makes it difficult to move an individual valve).	To avoid the formation of excessive soot, for which: 1. Use quality gasoline. 2. Do not start driving until the engine has warmed up to 80 degrees Celsius.
Noise and knock in the engine.	The most common cause is problems with hydraulic valve lifters.	It is eliminated only in the course of diagnosing and repairing the engine in a service station.
The engine is unstable, traction disappears, etc.	Clogged EGR valve	1. EGR valve failure can be avoided by constantly using high-quality gasoline. 2. Shut off the exhaust gas recirculation system

Typical malfunctions characteristic of all power units of this series are eliminated as follows:

FAULTS	CAUSE	SOLUTIONS
The engine gets very hot	1. The thermostat is out of order; 2. Clogged with dirt radiator; 3. Faulty pump.	The radiator must be cleaned of dirt, and faulty components replaced. It is recommended to change: - pump when replacing the timing belt; - the thermostat is changed every 50 thousand km.
The engine does not pull.	1. Clogged fuel pump screen. 2. Faulty high voltage wires.	Use good quality gasoline. Clean the pump screen from contamination. Replace high voltage wires.
Engine oil leaks through the valve cover gasket.	Mileage over 100 thousand km.	Change the gasket every 40 ... 50 thousand km.
Unstable operation of a cold engine.	The nozzles having an original design are clogged with dirt.	Clean the nozzles from dirt. It is recommended that this procedure be carried out at the service station.

tuning

Many tuning studios offer to use sports firmware to improve the technical characteristics of car engines. However, in this case, the Chevrolet Lacetti engine, as well as other power units of the Ecotec series, will receive smooth traction and a slight increase in output power.

A solid increase in power can only be obtained through a rather complex and expensive refinement of the engines.

• F16 D3 and F16 D4 motors

For power over 140 hp. With. necessary:

1. Bore the cylinders for a piston of 80.5 mm.
2. Install the crankshaft from the F18D3 engine with a stroke of 88.2 mm with the appropriate pistons and connecting rod.
3. Replace the existing camshafts with sports split gears.
4. You can also bore the inlet and outlet channels, grind them and install enlarged valves.

These improvements, along with sports firmware, will allow you to get a decent increase in power.

Similar results can be obtained if an RK-23-1 compressor is installed on the engine, providing a boost of 0.5-0.6 bar. In addition, you will have to replace the cylinder head gasket and install nozzles with a capacity of 360 cc and sports camshafts. Careful tuning of the power unit will allow you to get a power of about 150 liters. With.

• Motor F18D4

You can raise the engine power to 180 horsepower if you carry out a set of works on installing and configuring the TD04L turbine.

In addition to the turbine, it is necessary to purchase and install:

1. Intercooler.
2. Reinforced piston group with holes to reduce the degree of compression.
3. Sports camshafts.
4. Turbine oil supply system.

Chevrolet Lacetti is a popular sedan, station wagon or hatchback car that has become in demand all over the world.

The car turned out to be successful, with excellent driving characteristics, low fuel consumption and optimally selected power plants, which have proven themselves well for driving in the city and on the highway.

Engines

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

The Lacetti car was produced from 2004 to 2013, that is, for 9 years. During this time, they put different brands of engines with different configurations. In total, 4 units were developed under the Lacetti:

1. F14D3 - 95 hp; 131 Nm.
2. F16D3 - 109 hp; 131 Nm.
3. F18D3 - 122 hp; 164 Nm.
4. T18SED - 121 hp; 169 Nm.

The weakest - F14D3 with a volume of 1.4 liters - were installed only on cars with a hatchback and sedan body, station wagons did not receive ICE data. The most common and popular was the F16D3 engine, which was used on all three cars. And the F18D3 and T18SED versions were installed only on cars with top trim levels and were used on models with any type of body. By the way, F19D3 is an improved T18SED, but more on that later.

F14D3 - the weakest ICE on the Chevrolet Lacetti

This motor was created in the early 2000s for light and compact cars. He was great on the Chevrolet Lacetti. Experts say that the F14D3 is a redesigned Opel X14XE or X14ZE engine installed on the Opel Astra. They have many interchangeable parts, similar crank mechanisms, but there is no official information about this, these are just expert observations.

The internal combustion engine is not bad, it is equipped with hydraulic compensators, so valve clearance adjustment is not required, it runs on AI-95 gasoline, but you can also fill in the 92nd - you won’t notice the difference. There is also an EGR valve, which in theory reduces the amount of harmful substances emitted into the atmosphere by re-burning exhaust gases in the combustion chamber. In fact, this is a “headache” for used car owners, but more about the problems of the unit later. Also on the F14D3 uses a timing belt drive. The rollers and the belt itself should be changed every 60 thousand km, otherwise a break with subsequent bending of the valves cannot be avoided.

The engine itself is impossibly simple - it is a classic "row" with 4 cylinders and 4 valves on each of them. That is, there are 16 valves in total. Volume - 1.4 liters, power - 95 hp; torque - 131 Nm. Fuel consumption is standard for such internal combustion engines: 7 liters per 100 km in mixed mode, possible oil consumption is 0.6 l / 1000 km, but mostly waste is observed on engines with mileage over 100 thousand km. The reason is banal - stuck rings, which is what most of the running units suffer from.

The manufacturer recommends filling in oil with a viscosity of 10W-30, and when operating a car in cold regions, the required viscosity is 5W30. Genuine GM oil is considered better. Given the fact that at the moment the F14D3 engines are mostly with high mileage, it is better to pour "semi-synthetics". An oil change is carried out after a standard 15,000 km, but given the low quality of gasoline and the oil itself (there are plenty of non-original lubricants on the market), it is better to change it after 7-8 thousand kilometers. Engine resource - 200-250 thousand kilometers.

Problems

The engine has its drawbacks, there are many of them. The most important of them - hanging valves. This is due to the gap between the sleeve and the valve. The formation of soot in this gap makes it difficult to move the valve, which leads to a deterioration in operation: the unit troit, stalls, works unstably, loses power. In most cases, these symptoms suggest this problem. Masters recommend pouring only high-quality fuel at proven gas stations and starting to move only after the engine has warmed up to 80 degrees - in the future this will eliminate the problem of hanging valves or, at least, delay it.

On all F14D3 engines, this drawback occurs - it was eliminated only in 2008 by replacing valves and increasing the clearance. Such an internal combustion engine was called the F14D4, but it was not used on Chevrolet Lacetti cars. Therefore, when choosing a Lacetti with mileage, it is worth asking if the cylinder head was sorted out. If not, then there is a high probability of problems with the valves soon.

Other problems are also not excluded: tripping due to nozzles clogged with dirt, floating speed. Often the thermostat breaks on the F14D3, which causes the engine to stop heating up to operating temperature. But this is not a serious problem - the replacement of the thermostat is carried out within half an hour and is inexpensive.

Next - oil flow through the gasket on the valve cover. Because of this, grease penetrates into the wells of the candles, and then problems arise with high-voltage wires. Basically, at 100 thousand kilometers, this drawback pops up on almost all F14D3 units. Experts recommend changing the gasket every 40 thousand kilometers.

Detonation or knocking in the engine indicates problems with hydraulic lifters or a catalyst. A clogged radiator and subsequent overheating also occurs, therefore, on engines with a mileage of over 100 thousand km. it is advisable to look at the temperature of the coolant on the thermometer - if it is higher than the working one, then it is better to stop and check the radiator, the amount of antifreeze in the tank, etc.

The EGR valve is a problem in almost all engines where it is installed. It perfectly collects soot, which blocks the stroke of the rod. As a result, the air-fuel mixture is constantly supplied to the cylinders along with the exhaust gases, the mixture becomes leaner and detonation occurs, loss of power. The problem is solved by cleaning the valve (it is easy to remove and remove carbon deposits), but this is a temporary measure. The cardinal solution is also simple - the valve is removed, and the exhaust supply channel to the engine is closed with a steel plate. And so that the Check Engine error does not glow on the dashboard, the “brains” are reflashed. As a result, the engine runs normally, but emits more harmful substances into the atmosphere.

With moderate driving, warming up the engine even in the summer, using high-quality fuel and oil, the engine will travel 200 thousand kilometers without any problems. Next, a major overhaul will be required, and after it - how lucky.

As for tuning, the F14D3 is bored to F16D3 and even F18D3. This is possible, since the cylinder block on these internal combustion engines is the same. However, it is easier to take the F16D3 for the swap and put it in place of the 1.4-liter unit.

F16D3 - the most common

If the F14D3 was installed on hatchbacks or Lacetti sedans, then the F16D3 was used on all three types of cars, including the station wagon. Its power reaches 109 hp, torque - 131 Nm. Its main difference from the previous engine is the volume of cylinders and, consequently, increased power. In addition to Lacetti, this engine can be found on Aveo and Cruze.

Structurally, the F16D3 differs in piston stroke (81.5 mm versus 73.4 mm for the F14D3) and cylinder diameter (79 mm versus 77.9 mm). In addition, it meets the Euro 5 environmental standard, although the 1.4-liter version is only Euro 4. As for fuel consumption, the figure is the same - 7 liters per 100 km in mixed mode. It is desirable to pour the same oil in the internal combustion engine as in F14D3 - there are no differences in this regard.

Problems

The 1.6-liter engine for Chevrolet is a converted Z16XE installed in Opel Astra, Zafira. It has interchangeable parts and typical problems. The main one is the EGR valve, which returns exhaust gases to the cylinders for the final afterburning of harmful substances. Its fouling with soot is a matter of time, especially when using low-quality gasoline. The problem is solved in a known way - by turning off the valve and installing software where its functionality is cut out.

Other shortcomings are the same as on the younger 1.4-liter version, including the formation of soot on the valves, which leads to their "hanging". On the internal combustion engine after 2008, there are no malfunctions with valves. The unit itself works normally for the first 200-250 thousand kilometers, then - as lucky.

Tuning is possible in different ways. The simplest is chip tuning, which is also relevant for the F14D3. Updating the firmware will give an increase of only 5-8 hp, so chip tuning itself is inappropriate. It must be accompanied by the installation of sports camshafts, split gears. After that, the new firmware will raise the power to 125 hp.

The next option is boring and installing the crankshaft from the F18D3 engine, which gives 145 hp. It's expensive, sometimes it's better to take the F18D3 for a swap.

F18D3 - the most powerful on the Lacetti

This ICE was installed on Chevrolet in TOP trim levels. Differences from younger versions are constructive:

• The piston stroke is 88.2 mm.
• Cylinder diameter - 80.5 mm.

These changes made it possible to increase the volume to 1.8 liters; power - up to 121 hp; torque - up to 169 Nm. The motor complies with the Euro-5 standard and consumes 8.8 liters per 100 km in mixed mode. Requires oil in the amount of 3.75 liters with a viscosity of 10W-30 or 5W-30 with a replacement interval of 7-8 thousand km. Its resource is 200-250 thousand km.

Given that the F18D3 is an improved version of the F16D3 and F14D3 engines, the disadvantages and problems are the same. There are no major technological changes, so Chevrolet owners on the F18D3 can be recommended to fill in high-quality fuel, always warm up the engine to 80 degrees and monitor the thermometer readings.

There is also a 1.8-liter version of the T18SED, which was installed on the Lacetti until 2007. Then it was improved - this is how the F18D3 appeared. Unlike the T18SED, the new unit does not have high-voltage wires - an ignition module is used instead. Also, the timing belt, pump and rollers have changed a bit, but there are no differences in performance between the T18SED and F18D3, and the driver will not notice a difference in handling at all.

Among all the engines installed on the Lacetti, the F18D3 is the only power unit on which you can put a compressor. True, it has a high compression ratio - 9.5, so it must first be lowered. To do this, put two cylinder head gaskets. To install the turbine, the pistons are replaced with forged ones with special grooves for a low compression ratio, and 360cc-440cc nozzles are installed. This will increase the power to 180-200 hp. It should be noted that the resource of the motor will fall, the consumption of gasoline will increase. And the task itself is complex and requires serious financial investments.

An easier option is to install sports camshafts with a phase of 270-280, a spider 4-2-1 and an exhaust with a cut of 51 mm. Under this configuration, it is worth flashing the “brains”, which will easily allow you to remove 140-145 hp. Even more power requires cylinder head porting, larger valves and a new receiver for the Lacetti. About 160 hp eventually you can get.

On the appropriate sites you can find contract motors. On average, their cost varies from 45 to 100 thousand rubles. The price depends on the mileage, modification, warranty and general condition of the engine.

Before you take a "contractor", it is worth recalling: these engines are mostly more than 10 years old. Consequently, these are fairly worn-out power plants, the service life of which is coming to an end. When choosing, be sure to ask if the engine has been overhauled. When buying a more or less fresh car with an engine run up to 100 thousand km. it is desirable to clarify whether the cylinder head was rebuilt. If not, then this is a reason to “bring down” the price, since soon you will have to clean the valves from carbon deposits.

Whether to buy

The entire series of F motors used on Lacetti turned out to be successful. These internal combustion engines are unpretentious in maintenance, do not consume much fuel and are ideal for moderate city driving.

Up to 200 thousand kilometers, problems should not arise with timely maintenance and the use of high-quality "consumables", so you can safely take a car based on it. In addition, the F series engines are well studied and easy to repair, there are a lot of spare parts for them, so there is no downtime at the service station due to the search for the right part.

The best internal combustion engine in the series was the F18D3 due to its greater power and tuning potential. But there is also a drawback - a higher consumption of gasoline compared to the F16D3 and even more so the F14D3, but this is normal given the volume of the cylinders.

The Chevrolet Lacetti car has been produced since 2002 to the present. In the domestic market, the model is presented only with gasoline engines with volumes of 1.4, 1.6 and 1.8 liters. The timing belt on this vehicle differs depending on the engine size. So the strap numbers will be different.

Timing belt Chevrolet Lacetti 1.4 and 1.6

For Lacetti with F14D3 and F16D3 engines with volumes of 1.4 and 1.6 liters, the same timing belt is installed. From the factory installs the belt under the article GM 96417177. Price - 800 rubles. The manufacturer of the original factory belt is Gates. A direct analogue of the original belt from the manufacturer Gates has a number - 5419XS. Price - 740 rubles. In fact, these 2 parts are identical.

The original timing belt can also be found under the following subcodes from the Daewoo manufacturer: 96814098 , 96183352 , 96183351 . As a rule, they differ in price and marking color (not white, but red). Otherwise, they are completely identical. Thus, GM simply changes the prices of its products when the same timing belt comes out, but with a new part number, and already with a new price.

Timing belt characteristics for Chevrolet Lacetti 1.4 and 1.6

The timing belt is made from special rubber and reinforced with Kevlar for strength. There is also a special wear-resistant coating.

Among the factory belts in the original box, fakes are often found. Distinctive features of this part:

holograms are located on the packaging of the part;

the inscriptions on the belt itself must be “cut off”;

the packaging is sealed from the inside.

Also, as practice shows, belts with white inscriptions are faked much more often. Therefore, it is advisable, if possible, to take the original timing belt with a purple inscription.

In addition to the Gates strap, the most popular analogues of the factory timing belt GM 96417177:

• 1987949403 . The manufacturer is BOSCH. Price - 470 rubles. It has soft and strong rubber, with a dense rope layer inside. According to motorists, even on a used belt there are no damages.
• BL238. The manufacturer is AMD. Price - 320 rubles. Great budget replacement. According to the characteristics of this model of the belt is identical to the original. Has only positive reviews.

Note that along with the timing belt, the rollers also always change:

Timing Belt Chevrolet Lacetti 1.8

For Lacetti with an F18D3 engine with a volume of 1.8 liters, a timing belt with an article number is installed from the conveyor GM 96413861. The price of the part is 1700 rubles. The manufacturer is also Gates. Direct analogue of the original timing belt from the manufacturer Gates - 5499XS. Price - 980 rubles. The same belt from General Motors can also be found under a different article number - 24451895 from the manufacturer Contitech.

Timing belt characteristics for Chevrolet Lacetti 1.8

When looking for an alternative timing belt for Lacetti 1.8, you can pay attention to the most popular analogues:

• 1987949433 . The manufacturer is BOSCH. Price - 580 rubles. This spare part model is much more popular among buyers than the original. The reason is that the cost is lower than that of the original by an average of 2.5 times, with the same quality. Many belts of this model, even after working out the declared resource, do not show signs of wear and damage.
• CT 975. Producer - Contitech. Price - 780 rubles. This model is also popular among Chevrolet Lacetti owners due to its reasonable price and good quality, because it is a direct analogue of a belt with an article number 24451895 . Customer reviews of this part are overwhelmingly positive. He takes good care of his resources.

Together with replacing the timing belt on the Chevrolet Lacetti 1.8, it is also necessary to change the rollers:

You can buy parts as a set. The article of the original timing kit for the Chevrolet Lacetti 1.8 - GM 93745368. Price - 8300 rubles.

When to change the timing belt

According to, the timing belt should be replaced every 60,000 km, or 4 years of operation, regardless of engine size. According to the experience of many Lacetti drivers, the timing belt resource is longer, and there are many cases when he calmly looked after up to 80 thousand km. But this is all done at the driver's fear and risk, since when the timing belt breaks, the valves bend, the repair of which will cost much more than replacing the belt. Therefore, replacing the timing belt is better be carried out in accordance with the rules.

Finally sat down to write an article. Where to begin? Let's go in order. I watch on TV and on the Internet that many have a consumption of 9-10 liters on the highway and 13 in the city. Interesting - is it winter, summer or general. For me, as promised, the total average consumption for 4 years has now fallen to 8.5 l / 100 km. Considering that out of 12,000 km that I drive in 1 year - 10,000 city and only 2,000 highway, maybe less - then this is not bad. On-board computer shows everything correctly. From the very beginning I set it up accurately and now I periodically check its readings. Let's take a look at my expenses:

1) From the very beginning, I treated the engine, gearbox and power steering with the XADO additive. The quality of the additive was tested on my former machines. Then came the fakes. Last treated engine by » Suprotec »
. . 2) This machine does not like the cold. Consumption is approaching winter already at 10 degrees Celsius outside. The car starts to save noticeably after 90 degrees, and the thermostat is at 87 (for operation in Africa). In the block where DTOZH stands, the temperature is exactly 5 degrees lower, and the ECU receives a signal of only 82 degrees. And if you move along the highway, the thermostat either opens or closes, the temperature flies another 5 degrees and it turns out - 77. I set the thermostat to 92 degrees and all the readings are 5 degrees higher. And then with the first cold weather I already cover the car and the engine and the front grille. I try to keep the temperature above 90. If it goes higher, then at 97 the fan will turn on at low speed and drive it down to 92. You can’t even hear it. And do not look at the temperature arrow, it, which is 80, which is 105 in one place, did not warm up further. Officials said it was a design feature. This, by the way, on many foreign cars. I recently took measurements, you can see on this page
. . 3) I turned off the EGR valve so the engine gets more oxygen. There is a better combustion of the fuel mixture (more impact)
. . 4) I'm cheating the engine temperature. Each manufacturer makes machines with a margin of safety of 10 - 15 percent. Otherwise, all services would be full. Some wiring was oxidized and that's it — the car stopped. It is this stock that needs to be reduced to zero on a serviceable machine in order to get savings. I turn on the blende at 20 degrees in motion and it turns out immediately 43 and I don’t even feel it. There is a feeling only when starting off that the car is a little lacking in fuel. After warming up, the difference is 3 degrees. . 5) I also deceive the temperature sensor of the air entering the engine. What - no, but also savings.
. . 6) For more accurate indications of the absolute pressure sensor, the fitting of its connection was moved closer to the cylinders. At the beginning, I tried to blunt it a little with two resistances. One for the power wire and the other for the signal wire. But there were no big savings serviceable sensor, but it was timid to overtake. Or maybe he has already chosen the entire margin of safety. If you further deplete the fuel mixture, then the consumption, on the contrary, will increase, and the car will be dumb. Need to find golden mean.
. . 7) In daytime running lights I use LED bulbs. I measured them, and they both take only 0.1 amps. Let's count who rides in the dipped beam:
4 bulbs of dimensions of 5 watts each - 20 watts, two headlights of 55 watts each - 110. It turns out that we divide 130 watts by 12 volts, we get 10.83 amperes. I don't count the lights on the dashboard yet. In general, on my computer it shows an increase in consumption by 8 percent, and if you turn on the far one, then all 16.

8) I have one more plus - the car is not on the street, but in an unheated brick garage. But all the same, in winter the temperature there is 10 degrees higher, and even the engine is covered, and the car does not have time to cool down overnight, 10 degrees more than in the garage. At 20 degrees below zero, the engine temperature is 0. Therefore, I come, start the car, turn on the butt warmer, wait a couple of minutes until +3 and leave. While I close the garage already +15, I drove 30 meters and the temperature is already +20, I turn on the snag and go.
. . 9) And the biggest savings with our reliable, but voracious DBP sensor depends on the driving style. Engine power 1.6 is not enough for our car, although, as they say, it has a short box. I'll try to explain. If you switched to 4th gear in the city, pressed the gas to accelerate and are going to move 60 km / h, then when you reach this speed, the car seems to fall into a stupor. Due to the lack of power, it cannot accelerate to the degree corresponding to pressing the gas pedal. At this time, the working mixture is re-enriched, and it goes, for example, to 7 l / 100 km. It doesn't turn out to be a big stretch. And if you release the gas pedal a little, then the load on the engine will decrease, the mixture will become poorer, and the readings will already be 5 l / 100 km. Although the car itself was traveling 60, it will continue to move 60 km / h. On engines with DMRV, this is not as pronounced as with us with DBP. To better understand, try to ride 60-70 km / h in 3rd gear. There is already enough power here, and you yourself will, by intuition, lower the gas pedal. Have you seen in the video my readings from Moscow to Kostroma at 5.2 l / 100 km? So I drove all the way, the speed was no more than 100 km / h. From hills to neutral. It was a record. Usually I have 6.2 l / 100 km. when you don't follow the paddle.
. . I'm already tired, and you probably are. Let's summarize: You can't save a lot. Lots of things to steal . And you can save a little from all car systems, as they say with the world a penny.

One of the main units of the car is the engine. On the Chevrolet Lacetti, 3 varieties were installed. Without exception, all gasoline engines, volume: 1.4 1.6 1.8 liters.

How engines live

All engines are generally quite reliable, no critical remarks to the designs were noticed. It is very problematic to “stagger” the engine on the Lacetti. On the forums you can find information that engines without major repairs nursed at least 300,000 km. At such a run, many already have a pronounced oil consumption, which in most cases is eliminated by replacing the valve stem seals. All this, of course, subject to the timely replacement of engine oil, once every 15,000 km. The same information applies to engines equipped with LPG. They are in no way inferior to the "regular" gasoline engine. Also in the “red book” of Lachetka is a figure of 500,000 km for the entire car ...

It seems that the most popular 1.6-liter engine is not in vain. migrated to the Chevrolet Cruze.

Base gasoline engine

The volume of 1.4 liters, has a capacity of 94 horsepower. The engine is frankly weak and goes nowhere not "driving", in addition to this, an automatic transmission did not dock with it in principle. Although, we think you understand why. However, its advantages include the fact that the transport tax will be a modest amount.

most popular engine

1.6 has a capacity of 109 horsepower. Well, the most successful and coveted for Lacetto drivers is a 1.8-liter engine with a capacity of 122 horsepower, which very rare. In the days of its former popularity, for cars with this engine, and even in the station wagon, a lot of money came out on the secondary market! Even more than for a new car, which had to wait a long time.

For the 1.6 liter and 1.8 liter engine, a 4-speed automatic was offered. aisin for the 1.6 liter engine. ZF for 1.8 l engine.

Motors 1.4 and 1.6 are structurally identical. Therefore, the repair and maintenance of these engines are similar. In general, these engines are devoid of any design innovations and are quite easy to maintain, and affordable for most car owners. In fact, all the work comes down to the fact that you need to change the oil on time - once every 10,000 km. Monitor the condition of the spark plugs and change the timing belt every 60,000 km.

Engines have internal designations 1.4 - F14D3, 1.6 - F16D3, 1.8 - F18D3 / 18SED

The most common disadvantages:

Also, for all engines, a common problem, with a run of approximately 50,000 km, is oil leakage through the cylinder head cover gasket. It is noted that oil seeps both from the outside of the engine and into the candle wells. There is only one way out - gasket replacement.
Also to the disadvantages of the 1.6 liter engine. include the formation of soot on the valves. The harbingers of this problem are the “triple” of the engine and the deterioration of dynamic characteristics.
