Hyundai G6DA, G6DB, G6DC, G6DG, G6DJ engines

The Lambda engine family includes 6-cylinder power plants with different displacements. All motors are equipped with a timing chain drive. The largest internal combustion engine in the series is the 3,8-liter G6DA. Later, already in the Lambda 2 series, another such voluminous and more powerful unit was released - G6DJ.

Description of the Lambda series

G6DA Lambda

The Lambda 1 and 2 family of units is equipped with two types of injection: direct GDI and distributed MPI. All engines are powered by gasoline, have a V-shaped design of the cylinder block. Motors are installed on Hyundai/Kia premium models: Genesis, Grander, Ekus.

Engines have been manufactured since 2008 and have the following features:

• V-shaped design of the cylinder block (6 cylinders);
• 4 camshafts arranged according to the new QOHC scheme;
• two types of injection;
• dual timing control system D-CVVT.

The timing chain drive does not require maintenance, according to the manufacturer, but it is recommended to regularly monitor its condition.

Noteworthy are other characteristic features of the Lambda series motors:

• they are made of aluminum alloy;
• equipped with a plastic intake manifold that can optimize fuel consumption under unequal loads;
• equipped with mechanical valve clearance adjusters for a more compact cylinder head design - no hydraulic lifters;
• in order to reduce noise, a crankcase balance shaft is provided;
• poly-V self-tensioning belts are used as a cooling drive, power steering and a number of additional systems;
• in order to reduce vibrations, new ICE cushions are used, consisting of 3 passive units with regulators and solenoid valves.

A large member of the family, the 3,8-liter G6DA develops up to 260 horsepower at 6000 rpm, while its US version develops 4 horsepower. With. more. G6DJ develops up to 360 hp. With.

Family engine malfunctions

Now consider the characteristic problems of these motors:

• over time, piston rings may lie due to soot, after which oil burn and waste begin;
• direct injection engines suffer from accelerated carbon formation;
• can turn the crankshaft liners due to low oil level;
• it is necessary to adjust the thermal clearances of the valves manually every 70-80 thousand kilometers, since there are no automatic hydraulic compensators - this procedure at the service station is considered one of the most expensive;
• attachment belts may wear out ahead of time;
• possible floating speed due to clogged throttle.

Oil recommendation

For 6-cylinder Korean power units, it is recommended to periodically pour oils with a viscosity of 5W-20 or 5W-30. As for the lubricant class, all modern API and ILSAC for gasoline are suitable. However, I would like to point out a few important points.

1. 5W-20 is no better than 5W-30 - almost the same oils that are recommended for these engines not only by the manufacturer, but also by experienced users.
2. The composition must be updated strictly after 5-6 or, in extreme cases, 7 thousand kilometers, if the main operation of the machine takes place on the territory of the Russian Federation. We have expensive bad and dirty gasoline.
3. ACEA A1 oils are the most efficient.

Synthetic oils are persistent compounds that do not lose their properties for a long time, they also have good washing abilities. True, their disadvantage is the high cost, but it will pay off in the course of operation.

Now we present a list of oils that are most often recommended by experienced drivers and experts. First 5W-20.

1. Original Hyundai/Kia in 4 liter cans.
2. Pennzoil Ultra or Penzoil Platinum.
3. Petro-Canada Supreme Synthetic.
4. Red Line.
5. Mobile 1.
6. Likû Moli Special.
7. JT Energy.
8. Kih Ji 1.
9. Ravenol.
10. Quarker State Ultimate.

And now 5W-30.

1. Original Hyundai/Kia A5.
2. Petro-Canada Supreme Synthetic.
3. Pennzoil Ultra and Platinum.
4. Mobil 1 and Super.
5. Kih Ji 1.
6. Dragon SSU.
7. GT Ultra Energy.
8. Kendall JT.
9. Total Quartz and Quartz Futur.
10. Lotus Kuazar.

Mobil 1

These oils are expensive. If it is not possible to buy them, then you can use the list of less effective, but budget analogues. All of them are produced by Lukoil:

• Ssang Yong Motor Oil in liter cans - at a price of 300 rubles;
• SsangYong Motor Oil in 4-liter canisters - at a price of 1100 rubles;
• Uzavto Oil in liter containers - 250-270 rubles;
• Uzavto Oil in 4-liter cans - for 1000 rubles;
• Lukoil Lux and Lukoil Lux Premium - for 300 and 1000 rubles.

And then there's the middle class.

1. Petro-Canada Supreme Synthetic.
2. Zeke A.
3. Kih Ji 1 CM.
4. Dragon SSU.
5. Wolf.

Reviews about Lambda models

Blind Sniper	No one, by chance, has any information on the origin of this G6DB engine - whose development (it is unlikely that the Koreans invented it themselves), how modern is it, on what other machines (not only Korean) is it installed, etc.? I called Sokia - they don't know anything. They said that Kia's own development. I'm almost sure that they pointed a finger at the sky.
Fruit	With "Hyundai Grandeur" in my opinion there is a motor.
Varelius	The Hyundai Lambda engine family is the company’s modern all-aluminum V6. It is manufactured at Hyundai’s HMMA plant in Montgomery, Alabama. G6DB The 3.3 L G6DB version was introduced with the 2006 Sonata. It produces 235-247 ps (173 kW) at 6000 rpm and 238 ft·lb (304 N·m) at 3500 rpm. Applications: 2006 Hyundai Sonata, 2007 Hyundai Santa Fe 3.8 The 3.8 L (3778 cc) version produces 266 ps (196 kW) and 258 ft·lb (353 Nm). It has a 96.0 mm bore and 87.0 mm stroke.
Vlad	Please tell all owners of Sorika 3.3 at what winter temperature the engine started confidently. -23 outside. the engine started and stalled and so twice. then flooded. Mileage 3000 km wife drives. I advised her to turn on the ignition twice after a pause, wait and then start it - the result is negative. My Pradik at -30 is easy
Sean Charlie	I don’t presume to say for sure, but one of the main problems when a gasoline engine does not start in the cold is poor evaporation of gasoline vapors at low temperatures. As a result, in most cases (as I understand in your case too), the spark plugs are filled, and then gasoline fills the cylinders (depending on how long you turn the starter). On many engines (I don’t know about the 3.3 on Sorika) there is a “cylinder purging” mode - before turning on the ignition, you need to fully depress the accelerator pedal and turn the starter for several seconds (keep the pedal pressed all the way). In this mode, fuel is not supplied to the engine, and the remaining gasoline leaves the cylinders. True, “blowing through” may not help if the spark plugs then fail to produce a spark. In this case, the spark plugs must be unscrewed and either calcined or replaced with new ones. Another side effect: the “blown” gasoline from the cylinders goes into the exhaust system, and then burns there, which is completely unfavorable for the catalytic converter.
Merck	In this case, most likely the difference is in the composition of the mixture being prepared. And it depends on the brains, in particular, on the settings of Sorik for Euro-4 requirements, as Cry correctly said before me:
Edge	In general, there may be candles / wires ... I really never had such problems on anything, but they say that it happens ... By the way, in order to start at temperatures below 20 there is the following method: turn the starter in the usual way, if it starts up and work, then do not care. if it starts up and stalls, then we wait a couple of minutes, turn it again while gently pressing the gas pedal all the way, hold it for 5 seconds and just as smoothly release it, first hold it halfway for 3 seconds, then hold it completely for two seconds ...
Valery Grigoriev	I will add that + this is not a perfect start-up program, which, with each subsequent turn of the key in the ignition, supplies gasoline in the cylinder. Hence - flooded candles and the absence of a spark. The Kulibins have been chipping petrol-injected cars for a winter start for a long time, setting up a program that excludes the flood of candles. I just don’t know if this is implemented on the 3,3 engine in Sorento
Oleg 53	In general, the injector does not start (provided that everything is in order) due to the program and the temperature sensor. Especially cars from the Emirates sin, there is no program for -15 and below. It is necessary to diagnose. Someone already wrote about errors in the KIA program.
Gray	I started up at -27 after a week of inactivity at temperatures from -13 to -28, at first I immediately grabbed it and stalled, then I twisted it for 3 seconds, after that it started up and everything was fine
