Chevrolet F14D3 engine
Content
Developed at the beginning of the new century, this engine was intended for small and compact cars such as the Chevrolet Aveo/Lacetti. The 1.4-liter power unit is the result of the modernization of the Opel X14XE, developed in 1996. Both motors have the same shaft system mechanisms, and most of the parts fit, although there is no official data on this anywhere.
Device and description F14D3
The Chevrolet F14D3 engine is not bad, there are hydraulic lifters that eliminate the need for regular clearance adjustments. The power of the unit, despite the small volume, is quite acceptable. Food - gasoline A-95, but you can also pour the 92nd.
The EGR valve significantly reduces harmful exhaust by promoting the re-burning of harmful substances in the cylinders.
Initially, the F-series engine was the first to use 1.4 liters. This is an idea of engineers, which is aimed at the lowest possible fuel consumption by a car per 100 kilometers. An economical, but powerful power unit is the dream of many. Indeed, this engine on the Lacetti began to consume about 7 liters in the combined cycle - on the highway it consumed only 6 liters, and in the city - no more than 8,5 liters.
To reduce vibration and shock loads, the designers used the classic scheme. This is not only an in-line arrangement of the engine, but also the manufacture of liners for the block from the same material - cast iron.
The F14D3 engine has good potential for modernization. Due to the DOHC gas distribution scheme, it was initially possible to increase the power of a small-capacity engine. As for the potential, it is calculated by the manufacturer up to 120 horses, although in reality the tuners are seeking an increase of up to 180 horses (by installing a turbine).

Modification F14S3
The F14D3 engine has a modified version of the F14S3. They are equipped with Chevrolet Aveo cars going to the Ukrainian market. Engine characteristics are not much different from its predecessor:
- power increased to 83 liters. With.;
- timing diagram SOHC;
- the ignition system is similar;
- engine is short.
Service
Consider the known maintenance procedures for the F14D3.
- The most common procedure that is carried out on this engine is an oil change. It must be included in the list of mandatory work at least once every 15 thousand kilometers. In harsh operating conditions, the lubricant renewal period must be reduced. More than 3 liters of oil is poured into the crankcase if the filter is also changed. Without changing the oil filter, about 3,4 liters are poured. The manufacturer recommends pouring 5W-30 or 10W-30 in warm climates.
- The timing belt must be updated along with the tensioning mechanisms every 50-60 thousand km. You should be aware that when the belt breaks, the valves bend. For this reason, close attention must be paid to the belt. Having found traces of oil on it or loosening, urgently change the part without waiting for the replacement period.
- Spark plugs are also known consumables. Their timely replacement affects the operation of the engine. The frequency of replacement according to factory data should not be less than once every 50 thousand kilometers.
- The air filter needs to be replaced after 30 thousand kilometers. If this is not done, then the clogged part will let in little air needed by the motor, especially in the summer. As a result, don't be surprised if the engine overheats. Also, a dirty filter can be recognized by increased fuel consumption and reduced engine power.
- The coolant is changed every two years. It will take about 8 liters of refrigerant. It is better to fill in native antifreeze. It has a well-concentrated composition, there is distilled water. But mixing different coolants is not recommended, as this threatens with various problems.
Known motor flaws
The timing drive is a belt, which is not an advantage. Every 50-60 thousand kilometers it is necessary to change it with rollers in order to eliminate the risk of a break and bent valves. There is no valve-to-piston protection in this engine, so the problem occurs with a 90 percent probability in the event of a broken belt.
The most notorious flaw in the Chevrolet F14D3 engine has to do with valves. They tend to hang - a gap is formed between the valve and the sleeve, movement is difficult. Signs of this condition - the engine starts to triple, stall for no reason, lose power. The situation will only get worse if no action is taken. To avoid such a problem, it is recommended to always pour high-quality fuel, and the engine must be warmed up to 80 ° before driving the car.
The cylinder head must be carefully checked on used cars. It does not last long, so it needs to be repaired soon. The problem with the cylinder head was eliminated in 2008, when the engine was upgraded, other valves were installed, and the clearance was increased. The internal combustion engine began to be called Chevrolet F14D4.
Engine tripping at startup and unstable speed are also possible due to the characteristics of the injector - the nozzles are often clogged with dirt. It is recommended to clean the throttle body regularly, check the coils.
Often the thermostat on the engines deteriorates, the power unit begins to heat up to operating temperature worse. It is recommended to change the thermostat every 50 thousand km.
It happens that the F14D3 completely loses traction, the car stops driving. This is a sign of a clogged fuel filter. More precisely, dirt clogs the fuel pump mesh. It is also possible that the armored wires are damaged or there is a problem in the catalyst.
Another problem is related to oil leakage. It leaves through the valve cover seal, and then penetrates into the candle wells. From this immediately there are difficulties with armored wires. This is a known issue that occurs on an engine after 100 miles. Replacing the gasket every 40 thousand kilometers will make it possible to avoid this.
Knocks are evidence of problems with hydraulic lifters. Detonation occurs, which explains the nature of the noise. A similar sign can also be formed due to the fault of a catalyst that has outlived its resource.
As for overheating, the F14D3 rarely suffers from it. If such a situation arises, then the pump, radiator or thermostat becomes the cause. They get clogged over time, which leads to a rapid overheating of the motor.
The EGR valve, although it reduces the amount of harmful emissions, is really bothering many Russian car owners. The fact is that when refueling with low-quality fuel (and we always have it), carbon deposits quickly form on the sensitive European valve. From this, the engine begins to experience difficulties, ceases to drive normally. By plugging the EGR valve, many solve this problem.
So, high-quality fuel, a calm driving style, proper heating of the power plant, replacement of the lubricant in due time, will allow the F14D3 to pass 200 thousand kilometers without major repairs.
Where is the engine number
It is located on the cylinder block - right on the bump. It is recommended to treat it with "Kolchuga" or other chemistry in order to avoid abrasion.
These areas of the body tend to quickly rust, as a result of which it is impossible to read the number. Because of this, many Lacetti owners had to deal with expensive expertise.
Modernization
The first thing that comes to mind at the word engine upgrade is chipovka. It is possible if you can find an atelier professionally engaged in pouring sports, improved firmware. The result should show a little more than 100 liters. With. outlet, with stable traction. In fact, a slight increase, but many owners go for it.
If you want more, then you need to order Sport camshafts. Today, shafts with impressive phase data can be found on sale. Split gears, an exhaust called "spider" and new firmware are selected for them. The result will not keep you waiting long - 115-120 liters. With. This chip tuning mechanism is also applicable to the F16D3. On this engine, you can get even more - 125 hp. With.
The third version of chipovka is already for the pros. It involves boring the intake / exhaust channels. It is necessary to remove sharp corners, carry out grinding, install enlarged valves. This will give a tangible increase, but the engine life will be noticeably reduced.
Engine tuning also involves boring the cylinder block. It is the same for all modifications and analogues. Processing the block will make it possible to install the crankshaft from the upgraded F18D3 with a stroke of 88.2 mm. It will also be necessary to change the piston group with a pin offset, as well as bore the cylinder for a new, eighty-millimeter piston. The result of this refinement gives an increase in power of about 140 hp. With. The disadvantage is the increase in engine size and the high cost of operation.
Compressor installation is also possible on F14D3. This tuning method is much easier to carry out than boring. At the same time, the increase in power is the same. The best option is to use RK-23-1 or "St. Petersburg".
He is able to pump 0,5-0,6 bar, and this gives more than 50 percent increase. You will also have to slightly modify the compression ratio - reduce it by using a thick cylinder head gasket or two gaskets. We will have to install more efficient 360cc injectors, a new exhaust, phase-changed shafts, customizable by the engineering unit. A stable and smooth engine that produces at least 150 hp. s., secured.
The turbine will be an alternative to the compressor. You will need to use a different manifold, install an intercooler and new camshafts (narrower), as well as piping - tubes. As a turbine, you can take TD04L. This is the best way to tune the F14D3 - the engine will start to produce 170-180 hp. With.
The standard F14D3 engine is quite suitable for people who respect economy.
