Chevrolet F14D3 1.4L E-TEC Engine Full Complete Reviews

The engine of the Chevrolet F14D3 was assembled in South Korea for 6 years from 2002 to 2008. The engine has a volume of 1.4 liters and 4 valves per cylinder. There is a hydraulic lift, which negates the procedure for the driver to adjust the valve. The F14D3 engine shares many similarities with the Opel Z14XE and X14XE engines. Timing belt drive, there is a variable length VGIS intake manifold.

There is another modification to the F14S3 engine, which is distinguished by a reduction in power. Unlike the F14D3, the F14S3 has only one camshaft, which reduces engine power to 83 hp.

Chevrolet F14D3 1.4L Problems & Reliability

• The most common problems with the Chevrolet F14D3 engine is related to the valve. They tend to hang – gaps are formed between the valve and sleeve, movement is difficult. Signs of this condition – the engine starts tripling, shuts down for no reason, and loses power. The situation will develop unless action is taken. To avoid such problems, it is always recommended to pour high-quality fuel, and the engine should be warmed to 80 ° before starting the car.
• The valve cover is leaking. If the problem is triggered, oil will begin to seep into the spark plug holes. To avoid this problem, it is recommended to replace the valve cover gasket every 40-50 thousand km.
• The cylinder head should be checked carefully on used cars. It doesn’t last long, so it needs to be fixed immediately. The problem with the cylinder head was resolved in 2008, when the engine was modernized, another valve was supplied, and clearances were increased. The internal combustion engine is known as the Chevrolet F14D4.
• The thrust can be greatly lost if the EGR valve is overgrown with solid carbon deposits. To solve this problem, you have to clean the valve.
• Knocks are proof of a problem with hydraulic lifters. Detonation occurs, which explains the nature of the noise. Similar symptoms can be formed due to a catalyst error that has exceeded its resources.
• The engine does not warm up properly due to a worn out thermostat, here it does not have a long service life.
• The spin is floating, the engine is broken, then the nozzle may be clogged with dirt. Regular cleaning of the injectors and throttle valve is recommended.
• If the timing belt breaks, the piston bends the valve, so don’t delay replacing it. Timing belt replacement schedule 50-60 thousand km.
• The engine stops and the thrust disappears; the cause may be a clogged fuel filter.
• If the engine overheats, the cause may be in the pump or thermostat. In this F14D3 engine, the cooling system elements do not have a long service life. It is advisable to change the thermostat every 50 thousand km.
• At first glance, the F14D3 engine has a solid list of errors. However, many of these problems can be avoided by following maintenance regulations and using quality gasoline and engine oil.
• The engine of the Chevrolet F14D3 is decent, there is a hydraulic lift that eliminates the need for regular distance adjustments. The power of the unit, despite the small volume, is quite acceptable. Food – gasoline A-95, but you can also pour 92.
• The EGR valve significantly reduces harmful exhaust emissions by encouraging the re-combustion of hazardous substances in the cylinder.
• Initially, the F-series engines used 1.4 displacement for the first time. It was the engineers’ idea, aimed at the lowest possible fuel consumption of cars per 100 kilometers. An economical yet powerful powertrain is the dream of many. Indeed, this F14D3 engine starts consuming about 7 liters in a combined cycle – on the highway it consumes only 6 liters, and in the city – no more than 8.5 liters.
• To reduce vibration and shock loads, the designers used a classic design. This is not only the in-line arrangement of the machine, but also the manufacture of liners for blocks of the same material – cast iron.
• The F14D3 engine has good upgrade potential. Due to the DOHC gas distribution scheme, it is initially possible to increase the low volume engine power. As for potency, it is calculated by the manufacturer to be up to 120 horses, although in reality the tuner achieves an increase of up to 180 horses (by installing a turbine).

Chevrolet F14D3 1.4L Service

Let’s take a look at the known maintenance procedures for F14D3.

• The most common procedure performed on this machine is an oil change. It must be included in the mandatory job list at least once every 15 thousand kilometers. In difficult operating conditions, the lubricant renewal period should be shortened. 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 filled. The manufacturer recommends casting 5W-30 or 10W-30 in warm climates.
• The timing belt must be renewed together with the tightening mechanism every 50-60 thousand km. You should know that when the belt breaks, the valve bends. For this reason, pay close attention to the belt. After finding traces of oil on it or loosening, replace the part immediately, without waiting for the replacement period.
• Spark plugs are also known as consumables. Timely change affects machine operation. 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 parts will allow less air which the motor needs, especially in hot summer. As a result, don’t be surprised if the engine is overheating. In addition, a dirty filter can be identified by an increase in fuel consumption and a decrease in engine power.
• The cooler changes every two years. This will require about 8 liters of refrigerant. Preferably the original antifreeze content. The composition is concentrated in it, there is distilled water. But it is not recommended to mix different coolers, as this threatens various problems.

Chevrolet F14D3 1.4L Tuning

• A lot of people want to increase their iron horsepower and Chevrolet owners with the F14D3 engine are no exception. The first thing that comes to many people’s minds is, of course, the chip setup. You shouldn’t count on big upgrades, but 5-7 horses can be added to the stables.
• The second method involves installing the Sport camshaft, in addition to the new camshaft, you will also need gears and a spider exhaust. You also need to tune the motor properly. After all this, the F14D3’s power will jump to 120-130 hp. You can add another 10 hp by grinding the cylinder head channel.
• The third method is stroke, drilling the engine to adjust the 80 mm piston with an offset piston pin. You will also need to purchase a crankshaft from the F18D3 with 88.2 mm travel. With this improvement, power can increase by 10 hp again.
• The fourth, more serious way is to install a compressor, for example the RK-23-1, with a pressure of 0.5 bar. Apart from the compressor itself, it is necessary to reduce the compression ratio. This is done by attaching two cylinder head gaskets instead of one. You will also need a more efficient injector, such as a 360 cc, as well as an exhaust and tuner. The result is 150 hp. guaranteed at the same time there is no need to tinker with block boring.
• There are craftsmen who install turbines on the F14D3, but this will require a lot of money and serious rework. The TD04L turbine is suitable for installation. In addition to lowering the compression ratio, you will need oil supply to the turbine, intercoolers, exhaust manifolds for the turbines and more. As a result, it is possible to achieve a power of around 200 hp.
