Hyundai G4FA engine

This engine belongs to the Gamma series - a new line that completely replaced Alpha 2. The G4FA engine has a volume of 1.4 liters. It is assembled on one business center, uses a chain instead of a timing belt.

Description of G4FA

The G4FA engine has been in production since 2007. A model from the new Gamma family, it is installed on Korean class B cars, including the Solaris and Elantra. The design scheme of the motor includes a lightweight BC with thin cast iron sleeves.

The engine life declared by the manufacturer is 180 thousand km. This is even lower than that of the VAZ models. But, of course, with a calm driving style and periodic replacements of worn out consumables, 250 thousand km for this motor is not the limit. However, a large mass of drivers do practically nothing, but only take the car to MOT according to the regulations. Therefore, already after the 100th run, difficulties begin.

G4FA Service Policy

The timing chain works with tensioners, and according to the manufacturer, it does not require maintenance during the entire operational period. Thermal gaps need to be manually adjusted, since the G4FA does not have automatic hydraulic compensators. This is done every 90 thousand km - the valve clearances are adjusted by replacing the pushers. If you ignore this process, it will cause problems.

G4FA sores

Korean engine cylinder head

Consider the known problems with the G4FA engine:

  • noise, knock, chirp;
  • oil leak;
  • swimming revolutions;
  • vibration;
  • whistling.

Noise in G4FA is caused by two reasons: the timing chain or valve knocks. In 90 percent of cases, the chain knocks. This usually happens on a cold engine, then as it warms up, the knock disappears. If a hot engine is noisy, these are already valves that require immediate adjustment. As for the chirring sounds and clicks, this is normal, nothing needs to be done - this is how the nozzles work.

An oil leak on the G4FA is always associated with cylinder head gasket wear. You just need to replace it, and continue to operate the car. But swimming speed is caused by clogging of the throttle assembly. It is necessary to clean the damper, and if it does not help, reflash the control unit.

A dirty throttle assembly can also cause engine vibration at idle. Strong motor shocks also appear from faulty candles or clogged dampers. Replacing the sparking elements and cleaning the damper will help solve the problem. Very strong vibrations occur due to the fault of the relaxed supports of the power plant.

It is noteworthy that the developers themselves warn engine owners that vibrations are possible at medium speeds due to the features of the G4FA model. Due to the fault of the universal, characteristic design of the power plant supports, all vibrations are transmitted to the steering wheel and other areas of the machine. If at this moment you accelerate or abruptly release the accelerator pedal, the engine will come out of the mesomeric state, and the vibrations will disappear.

And finally, the whistle. It comes from a sagging, not well-tightened alternator belt. To get rid of unpleasant noise, it is necessary to change the tensioner roller.

The G4FA engine is called disposable by repairmen. It means that it is difficult to restore, some elements are almost impossible to repair. For example, there is no standard for many internal combustion engines for cylinder bores for the repair size. You have to change the whole BC. But recently, some Russian craftsmen have learned to sleeve the BC, thereby increasing the life of the motor.

Modifications of G4FA

The first modification is the 1.6-liter G4FC. The main differences between them are the volume and the presence of automatic valve controls on the G4FC. In addition, the FA develops 109 horsepower. s., and FC - 122 liters. With. They also have different torque: 135 versus 155, respectively.

Recently, other versions have been released, already more modified - G4FJ and G4FD. The first unit with a T-GDI turbine, the second with a direct injection system. The Gamma family also includes G4FG.

Tuning G4FA

Chipovka is one of the easy, fast and cheap ways to increase traction. After such tuning, the power will increase to 110-115 hp. With. However, there will be no serious changes if you do not install a 4-2-1 spider and increase the diameter of the exhaust pipes. You will also need to refine the cylinder head - increase the valves - and flashing. In this case, an increase in power up to 125 hp can be achieved. With. And if you add all this sports camshafts, then the engine will become even stronger.

Installing a compressor is the second tuning option. This is an extreme measure of modernization, since the engine resource in this case is noticeably reduced.

  1. It is possible to prepare a new lightweight PSh group for the ratio of the over-piston space to the volume of the combustion chamber in the value of 8,5. Such a piston can withstand a pressure of 0,7 bar without problems (not a very productive turbine).
  2. For some strengthening of the cylinder head, it is recommended to put 2 gaskets instead of one. This is much cheaper, but this option will withstand a boost of only 0,5 bar.

In addition to the compressor itself, a new exhaust with a pipe diameter of 51 mm is installed. Engine power will increase to 140 liters. With. If you additionally machine the intake / exhaust channels, the engine will increase to 160 hp. With.

Turbine installation is the third option for finalizing the G4FA engine. However, in this case, a more professional approach is needed. First of all, you need to weld a new reinforced manifold for the Garrett 15 or 17 turbine. Then organize the oil supply to the turbine, install the intercooler, 440 cc nozzles and build a 63 mm exhaust. It does not do without shafts, which should be made with a phase of approximately 270 and a good lift. A well-tuned turbine will give an increase in power up to 180 hp. With. The method is expensive - it costs almost half the price of the car.

Advantages and disadvantages

First, the pros:

  • the motor practically does not bother up to 100 thousand km;
  • it is cheap to maintain;
  • standard procedures are easy to follow;
  • the engine is economical;
  • it has good cylinder capacity.

Now the cons:

  • on a cold engine it makes a lot of noise;
  • periodic oil leakage due to weak cylinder head gasket;
  • fluctuations, dips in HO/CO;
  • there are difficulties with the sleeve.

Checking clearances in the valve drive Hyundai Solaris, Kia Rio
AndreiThere is no timing belt in the G4FA engine, its function is performed by the timing chain, which is a plus, since it does not need to be replaced, according to the manual, it regularly serves throughout the entire engine life. The timing chain is great, no need to spend money on periodic timing belt replacements. But do not rush to rejoice. The fact is that the engine is disposable and having given such a design to the engine, the Hyundai Motor Company did not provide for the possibility of a major overhaul after the resource was exhausted. The G4FA motor has a not so big resource, only 180 tons. Km. An engine can be repaired only by replacing a worn aluminum cylinder block and other worn components (pistons, cylinder head, crankshaft, etc.), which is much more expensive.
RossoffOur family has an i20 with a 1.2 engine, more than 200 thousand mileage, during this time nothing has changed except oil and filters, it works fine and is not going to be measured, the hydraulic lifters do not even knock. In general, this is also suitable for 1.6 ... They have no fundamental differences, well, not counting the sizes of pistons, boilers, shafts
OlegThe G4FA engine has a rev. valve timing only on the intake shaft. It does not have hydraulic lifters, for this reason, after 95000 km, it is necessary to adjust the valve clearances by replacing the pushers, this is not cheap, but here it is better not to save on costs, otherwise there will be much more problems.
IonicThese engines fail even at 10 thousand mileage, are very demanding in terms of fuel quality, refueled shit 5-10 times and goodbye, oppression and tears the connecting rods, etc., it is also strictly forbidden to pour additives, they are afraid of water (it can get inside, technical shortcomings) after washing or driving through deep puddles, a river. engines are “hot”, frequent oil changes are required, engines are being repaired
Guest workerYou have probably read the Internet. And you have no idea what kind of motor it is. There are more than 100 Rios and Solaris in our taxi fleet. on some, the mileage is already over 200k. And of course, no one chooses “fuel quality” or similar crap. The very minimum cost. They drive in the tail and in the mane. Then they put pretty numbers on the odometer and sell them to suckers. And they “fail even for 10 thousand ...”
Glowpreset1,6 gdi (G4FD) with a Korean accent and 140 forces and 167 torque will be factory. Well, if it doesn’t work at all then G4FJ. I do not approve, but I think all this will be with a minimum of crap. and in Rio and Solaris. Yes, and for the price of building a turbine, it will probably be comparable
Evgeniy236guys I work on auto parts, and I saw liners, connecting rods, camshaft, crankshaft, pistons, etc., so the engine is being repaired, why are they selling it then. Yes, and the block cannot be sharpened because thin walls are selected and machined from solid material
From RomeI remember on the drive there was a BZ of a solarisovoda who sleeved the block without any problems ... you just need a specialist with hands, from where you need =)
MaineRepair sizes do not exist. Denomination only.
ZolexUnrepairable g4fa due to high material costs. You will need to completely sort out the motor, part of the repair requires special. equipment, labor intensive. It's easier to find a contract. Parts are sold for the repair of engines that have passed up to 100 thousand km.
Driver87About a resource of 180t.km - nonsense! Solaris has run far beyond 400! A GUARANTEED service life of 180t.km is not a resource!
MarikA well-known and annoying drawback is a knock in the motor. If the knock disappears after warming up, the reason is in the timing chain, if so, then do not worry. When knocking on a warm engine, it is necessary to adjust the valves. There have been cases of detection of incorrect adjustment on new cars. Prepare money, service workers will be happy to make adjustments. The designers did not pay attention to the noisy operation of the injectors, which in no way affects the serviceability of the motor, but you must admit that when something in the engine rattles, clicks, clatters or chirps, it causes discomfort.
Help88The inconsistency of the speed (float), the motor runs unevenly is a fairly frequent drawback. The problem is eliminated by cleaning the throttle valve, if cleaning did not help then they do the firmware with new software.
