Chevrolet F16D4 engine

This motor was installed more often on Chevrolet Cruze and Aveo cars. The new 1.6-liter power unit was obtained from the predecessor F16D3, but in fact it is an analogue of Opel's A16XER, released under Euro-5. It was equipped with a universal automatic adjustment of the valve timing VVT. One of the main problems of the predecessor has been solved - on the F16D4, the valves do not hang, there is no exhaust recirculation system, and the hydraulic lifters have been replaced with calibrated cups.

Engine description

F16D4 engine

In practice, the engine can withstand a resource of 250 thousand km. Obviously, this largely depends on the operating conditions. If you periodically load the motor, do not carry out maintenance in a timely manner, the service life of the unit will decrease.

F16D4 is capable of delivering 113 hp. With. power. The engine is powered by distributed injection, which is fully monitored by electronics. This made it possible to increase the power of the power plant, but there were problems with the solenoid valves of the phase regulator. They start working like a diesel after some time, with noise. They need to be cleaned or replaced.

This is the same row "four" as its predecessor. One common crankshaft, two overhead camshafts. The engine is cooled by antifreeze, which circulates in a closed system.

The cylinder head is cast from an aluminum alloy, slightly different from the F16D3 engine head. In particular, the cylinders are purged in a transverse pattern. Different inlet/outlet valve diameters, stem diameters and lengths (see table for details on dimensions).

The EGR valve has been removed on the new engine, which is a big advantage. There are also no hydraulic lifters. It is advisable to fill in gasoline with the 95th so that there are no special problems with the functioning of the engine.

Thus, the new motor differs from the previous one in the following characteristics:

• the presence of a new intake tract with variable geometry XER;
• the absence of an EGR valve, which eliminates the ingress of exhaust gases into the intake when starting the engine;
• the presence of the DVVT mechanism;
• the absence of hydraulic compensators - calibrated glasses are much simpler, although manual adjustment must be carried out after 100 thousand kilometers;
• increased overall service life - subject to standard rules, the motor will pass 200-250 thousand kilometers without any problems.

How DVVT works

What is extremely important and interesting: with such extensive changes, the scheme of the former engine, which deserved much praise, was not touched. This is the same economical aspirated with an in-line arrangement of cylinders.

It will be interesting to consider also other features of this engine. For example, careful work on the phase control system has improved the quality of ignition. The new cylinder head deserves a lot of good words, in which the cylinders are blown transversely, unlike the previous F16D3 engine.

Service

The first step is to pay attention to the timely oil change. On Cruz and Aveo cars, according to the regulations, it is necessary to renew the lubricant every 15 thousand kilometers. The volume of the crankcase and system is 4,5 liters. Therefore, if you change the filter at the same time, then you need to fill in exactly that much. If an oil change is carried out without a filter, the system will hold 4 liters or a little more. As for the recommended oil, this is the GM-LL-A-025 class (see the table for details). From the factory, GM Dexos2 is pouring.

The second is behind the timing belt. It is not as sensitive as on the old F16D3, it does not break after a short operation. The original belts serve 100 thousand km or more, if there are no other reasons for the break (oil ingress, crooked tuning). Belt replacement must be accompanied by the installation of new rollers.

Maintenance of other consumables.

1. Spark plugs also need timely care. According to the regulations, they withstand 60-70 thousand kilometers.
2. The air filter changes after 50 miles.
3. According to the passport, the refrigerant must be changed every 250 thousand kilometers, but in practice it is recommended to reduce the replacement period by a factor of three. Pouring should be the option recommended by the manufacturer (see table).
4. Crankcase ventilation must be purged every 20 thousand km.
5. Change the fuel pump after 40 thousand kilometers.

Motor advantages

Here they are, the advantages of the modernization.

1. The quality of the lubricant no longer plays such an important role as on its predecessor.
2. Almost completely disappeared problems with turnover on the twentieth.
3. Antifreeze is used sparingly.
4. The overall service life has been increased.
5. The engine complies with Euro-5 standards.
6. Maintenance and repair are simplified.
7. Attachments are better thought out.

Weaknesses and malfunctions

Consider them in more detail.

1. There are no oil leaks anywhere. It leaves through the valve cover if the gasket is not replaced in a timely manner.
2. The “comb” of the ignition module has not been improved.
3. The electrical control of the thermostat breaks down quickly.
4. The cooling system does not always cope with intense thermal conditions.
5. Breakdowns of DVVT pulleys are often observed.
6. Due to the deliberately narrowed section of the exhaust manifold for Euro-5, exhaust volumes increase. This is an extra load on the muffler, increasing the risk of overheating and reducing power.

If the timing belt is not replaced in time, the valve will bend due to a break. In addition, the F16D4 engine can eventually "sick" with a loss of power. This is due to the failure of the DVVT system. It is urgent to replace the shafts, adjust the valve control phases.

If misfiring or no ignition is observed, then this is most likely due to a breakdown of the ignition module. In this case, repair will not help, only replacement will save.

Another common malfunction of this motor is overheating. It occurs due to a malfunctioning thermostat. Replacing the element will help correct the situation.

If the fuel consumption suddenly increases, then the rings may be stuck or the DVVT system has broken. Need repair or replacement parts.

Engine modernization

An exhaust manifold

A modified version of the F16D4 is known, which produces 124 hp. With. This engine uses a new intake manifold system, the compression ratio is increased to 11.

A certain increase in power is quite possible if you put a 4-2-1 spider type exhaust system. You will need to remove the catalytic converter, the receiver and reflash the brains. About 130 l. With. guaranteed, and this is without installing a turbine.

As for turbocharging, an optimal set of works should be carried out. In particular, before boosting, you should correctly prepare the engine: bring the compression ratio to 8,5, install the correct connecting rods, and the TD04 turbine. It is also necessary to install an intercooler, new pipes, exhaust on a 63 mm pipe, set up online. All this will cost a lot of money, but the power will increase to 200 liters. With.

Hsien	Problem areas of this engine: 1. Solenoid valves of the phase shifter - 2 pieces (price from 3000 per piece); 2. Ignition module (the price is usually from 5000 rubles); 3. Throttle valve block (from 12000 rubles); 4. Electronic gas pedal (from 4000 rubles); 5. The cap of the expansion tank with a valve (the valve turns sour, as a rule, it bursts the expansion tank or pipes of the cooling system) - it is advisable to replace it at least 1 time in 1,5 years
Vova “Round”	Recommendations for antifreeze: Initially filled with GM Longlife Dex-Cool antifreeze. Color: red. Before pouring, it must be diluted with distilled water in a 1:1 ratio (concentrate). Original number for liter container: code 93170402 GM / code 1940663 Opel. The antifreeze level on a cold engine should be between the min and max marks (seam on the tank). For the lubrication system: GM Dexos 2 5W-30 oil (code 93165557) where dexos2 is the specification (roughly speaking, the manufacturer’s approval for use in this engine). To change the oil (if you don’t want to buy the original one), oils with Dexos 2™ approval are suitable, for example MOTUL SPECIFIC DEXOS2. Oil volume for replacement 4,5 liters
Thick	Tell me, is it possible to fill the engine with ZIC XQ 5w-40 oil for the summer? Or necessarily GM Dexos 2 5W-30?
Mark	Let's clarify the situation: 1. if you don't give a damn about the manufacturer's warranty, then you can pour any oil that you like 2. if you don't give a damn, but you want to pour the oil that you consider the best, then you need to pour oil with a DEXOS2 approval and it may not necessarily be GM, for example MOTUL
Aveovod	can you tell me more about this Dexos? What is it? What is its role?
T300	In general, what kind of resource do these engines have? Who knows? With moderate use?
Yuranya	dexos2™ This is the proprietary technical standard of motor oil from the engine manufacturer, car manufacturer, and brand at the same time. But, of course, in essence it’s just linking clients to offline sites. services (not many people would think to look for nuances), to their own oil, making money from “their” oil, from a maintenance service. My opinion: GM Dexos2 oil is most likely hydrocracked oil. It runs well for 7500 km. Driving it, especially in Russian conditions, 15 km is a significant overkill. Especially on an engine with phase shifters. In general, in practice it is about 000 km.
Autoed	My Aveo is 3 year and 29000 months old. mileage 6000 oil pour GM. I change every XNUMX km. no problem!!!
Yuranya	And I have a new one, at 900-950 rpm, some slightly uncharacteristic sound. Podrykivanie roller probably. That growling slightly against the background of everything else. But not everyone hears this.
And you need complete silence around to catch. . But below 900-950 rpm or higher, the sound is smooth, purely motor.
