Hyundai G4KE engine

Hyundai Corporation over time increased the G4KD engine by installing a crankshaft with a piston stroke of 97 mm. The result was a new 2,4-liter G4KE engine with the same system for changing the phases of the hydraulic distribution system on the shafts, without hydraulic lifters, with the same malfunctions. Knocks, noises and extraneous sounds have not disappeared anywhere, but the new unit - a copy of the Japanese 4B12 - was developed jointly with Mitsubishi under the World Engine program, which automatically increased its reputation in the eyes of users.

Description of the G4KE engine

G4KE engine

G4KE was gradually transferred to Europe, began to be produced in Slovakia, at its own facilities. Initially, the motor was with one phase regulator and a conventional sump. Then two phase regulators appeared, an improved sump and the volume of oil in the system increased. The applicability of this power unit is quite wide - many cars received it in addition to Hyundai, because models of the famous Mitsubishi are also included here. The engine belongs to the Theta 2 family, which replaced the outdated Beta series. The designers managed to introduce the latest improvements. The series was also called the Chrysler Ward.

The difference between the G4KE and its predecessor G4KD in the increased piston group was not in vain. This made it possible to increase the power of the internal combustion engine, to somewhat stabilize the speed. Otherwise, there are no structural differences from the younger brother. The BC and cylinder head of the engine are lightweight - they are made of 80% aluminum. The timing drive is a reliable metal chain that will run for a very long time if you monitor the part in a timely manner, fill the engine with high-quality oil and fuel. It is also important to correctly set the tightening torque.

Service regulations

Maintenance for this motor is carried out according to standard criteria. The service interval of the main procedures is 15 thousand kilometers. Unless the engine is operated in harsh conditions, then the maintenance period must be reduced.

Consider the technical measures that must be carried out on this internal combustion engine:

• change oil every 7-10 thousand kilometers;
• at the same time during this period, update the oil filter;
• update the air and fuel filters every 30-40 thousand kilometers - if the operating conditions are difficult, the roads are dusty, then the replacement period for the VF should be reduced to 10 thousand km;
• change spark plugs every 40-50 thousand kilometers.

Castrol oil

It is recommended to fill the G4KE with 5W-30. The system holds 5,8 liters of grease.

Valve setting

Checking and adjusting the valves must be done on a cold engine. The temperature of the refrigerant must not exceed 20 degrees Celsius.

Learn more about regulation.

1. Take off the motor cover.
2. Dismantle the cylinder head cover together with the gasket, having previously disconnected the attachments.
3. Raise the piston of the 1st cylinder to TDC by turning the crankshaft and aligning the risk with the corresponding mark on the engine housing. At the same time, check that the mark on the camshaft sprocket is facing the cylinder head. Otherwise, you need to rotate the crankshaft 360 degrees.
4. Measure valve clearances using a feeler gauge set. On the intake valves, the maximum permissible value is 0,10-0,30 mm, on the exhaust valves - 0,20-0,40 mm.
5. The gaps must also be measured by turning the crankshaft 360 degrees and aligning the risk with the mark on the timing chain guard.

Valve adjustment for Sportage

To adjust the gaps, the piston of the 1st cylinder must be set to TDC, look at the crankshaft risk on the timing chain and camshaft sprocket. Only then can the bolt of the timing chain protection manual hole be pulled out, releasing the ratchet. Next, you need to remove the front protection of the camshaft bearings and measure the removed cam using the device. The size of the new cam must be selected strictly according to the standard values: -0,20 mm at the inlet and -0,30 mm at the outlet. As for the size of the gasket, it should be 3 mm.

Further actions.

1. After installing a new cam on the cylinder head, the intake camshaft is installed.
2. Timing chain marks and camshaft sprocket are aligned.
3. Installed exhaust camshaft.
4. The bearing protection and the service bolt are put in place - it is necessary to tighten with a torque of 11,8 Nm.
5. The crankshaft rotates two revolutions clockwise, the valve clearance is rechecked. At the inlet it should be 0,17-0,23 mm, and at the outlet - 0,27-0,33 mm.

G4KE Engine Malfunctions

Here are the most common problems that occur on this motor.

1. Noisy work that worries owners after 50 thousand kilometers. This can be the chirping of injectors - easily eliminated by adjusting the injector, or increased vibrations associated with worn spark plugs.
2. Swimming revolutions due to clogging of the throttle assembly.
3. Failure of the phase regulators and the bearing of the compressor conda.
4. Failure of the oil pump - it is extremely important to monitor the lubricant pressure, at the slightest doubt, turn off the engine. Otherwise, problems with the engine cannot be avoided - scuffing on the inner walls of the cylinders is only a small part of what can happen.

Clean throttle

Breakdowns that require the removal of the power plant on the G4KE are rare. Basically, removing the head is enough. However, in the absence of proper experience, difficulties may arise.

Modifications

In addition to this ICE, the Theta 2 family also includes:

• G4KA;
• G4KC;
• G4KD;
• G4KG;
• G4KH;
• G4KJ.

Modernization options

Today, various tuning studios offer options for flashing the ECU of this motor with a subsequent increase in power up to 200 hp. With. However, just chipovka is unlikely to give such changes, because in order to squeeze so many horses out of the engine, you will also have to carry out a number of additional upgrades:

• install forward flow to the exhaust;
• replace the exhaust manifold - put a spider 4-2-1 or 4-1;
• adjust the camshafts with a phase of 270.

Various compressors and turbines will fit well on this motor, but the situation will become more complicated due to the selection of a new box. In addition, the car must be comprehensively prepared for higher power. G4KE turbocharging is rarely done: firstly, it is expensive, and secondly, the resource of the unit is noticeably reduced.

What cars was installed on

The G4KE engine was installed on the following Hyundai models:

• Santa Fe CM 2007-2012;
• Sonata NF 2008-2010;
• Sonata LF 2014;
• Santa Fe DM 2012-2018;
• Sonata YF 2009-2014;
• Tuscon LM 2009-2015.

Hyundai Tuscon

As well as Kia models:

• Magentis MG 2008-2010;
• Sportage SL 2010-2015;
• Sorento XM 2009-2014;
• Optimu TF 2010-2015;
• Sportage QL 2015;
• Sorrento UM 2014

In general, reviews about the operation of the motor are positive. Although there are a number of disadvantages, subject to the basic rules of operation, the ICE resource increases, problems with the details described above can be avoided. G4KE and 4B12 engines are completely interchangeable, so feel free to order consumables in stores and for Mitsubishi.

Engine G4KE 2.4 repair Kia Sorento Ch.1

Kolya	Tell me about the oil consumption of the engine 2.4 Kia ​​Sorento 2014. On a run of 25000 km, I had to add 400 grams of oil, earlier, before the first MOT, the oil level did not change (during the second MOT, the servicemen changed the oil in the internal combustion engine from Shell 5W40 to Total 5W30). Tell me please. do you have to add oil and how much?
Surfer 82	I bought a car with a mileage of 45 thousand. And I found out unpleasantly that I had to constantly watch the oil level. There is an oil burner. Changed the oil. flooded on max will look. It used to be 1 liter per 1000 km. When changing the oil, I saw that the service station did not put a gasket under the drain plug. Therefore, the entire pan was covered in oil. although it did not drip, because I have a big engine. True, today after 250 km. run in the country saw that the level again began to leave, I still hope for an uneven surface and an error. When I saw a loosely closed plug without a gasket, I decided that I had found the problem of the oil burner, but now I don’t know.
victorian	It is likely that the true mileage is much higher for a 2012 car, hence the “zhor” oil
Andrei	I used to be mistaken when I told people that it was not necessary to adjust the clearances on 4V10/11/12 motors. Sorry - I was wrong! It is necessary, with a run of about 100t.km. at least check the gaps, the procedure is not expensive. Already on more than a dozen cars, I was convinced of this. Cars with gas equipment, check every 20-30t.km., otherwise cylinder head repair, and there is completely different money) The most important thing is to have a set of adjusting cups) There were cases when the metal of the cup just sagged!
Andy Matrix	Comrades. Tell me this. How problematic is the 2.4 engine? And then I opened a branch on this movement (this branch) and on the first page 5 (FIVE) topics on the wedge / engine replacement. I immediately tensed up. I thought that, that, but the engine is trouble-free here. And now something began to doubt. I rode earlier on the KM spratage, accent and sanat of Tagazovskih. Are there any statistics on broken engines? Mileage or year of manufacture.
Ruud Himmler	In my opinion, the engine is trouble-free, just change the oil more often and don't worry.
Mosya	I still advised you to carefully monitor the engine ... especially for the mileage of more than 100k !!! change the oil more often and pour oil only with those tolerances that are indicated in the instruction manual !!!
Sergey92	I have 2010 mileage 76tyr. Oil does not eat at all, for a year with a run of 7-10 thousand, the level does not fall below the lower mark, never topped up.
Roma Bazarov	the level on this engine must be kept at the top ...
YurikYurik	According to my logic, gasoline G4KE, the oil level in the internal combustion engine should be kept at half, because he likes unnecessary 4,5-5 tons rpm. with cruise activated.
Sidoroff68	Engine 195. Oil is topped up only if the son frolic. I also drive fast, but xs what he does with it. Not always, but 000 liter. top up at 1. At 15, the attachment drive belt fell apart - replacement with all rollers. The valve cover gasket got stuck - replaced it. All. Yes, the engine is chipped from 000 km.
Maxon	Hello everyone. I’m trying to describe briefly what happened and what I ask for help, practical advice. With a run of 70 thousand, the connecting rod broke and the block was pierced, the car service said it could not be restored, they say look for a contract engine. Sorento 150 release volume 2012 liters, power 2.4hp, engine model G174KE. What difficulties or problems can I face when purchasing a used engine. Thank you for your attention.
Bay Lohov	Documents for the motor require the type of certificate, invoice or release of the chest unit. Choo, it's time for a change in terms of not reconciling numbers. In our EKB, for example, for a year now they have been checking numbers on motors.
Alex D	I also knocked at 64000 km, changed it under warranty, it remains to drive 800 km, then I’ll change the oil, by the way, the car is also December 12, about the contract (WHAT IS YOUR car NOT WARRANTY ???) ....... as a rule, they give a guarantee from 1-4 weeks, and so visually, when buying, inspect if there are any damages, then install and ride, while there is a small guarantee! I think there are no other options here, to some extent a pig in a poke, BUT how differently (maybe, of course, with them they will be allowed to at least remove the valve cover, look at the state in the head ....
Fedka	150 thousand is expensive!!! They brought me a contract engine from Austria. And to the border they tested it twice at the stand. The mileage on it was 70 thousand. This is if you do not have a guarantee. It is possible that they will deliver without attachments.
Surik	There was a broken rod. Repaired under warranty (parsing and approval 1 month). repair 7 days. Replacing the shot block assembly, chains, oil pump, dampers, valves and guides in the 3rd cylinder, and a bunch of other things (a list of 47 items including bolts and gaskets)
