Engine Mitsubishi 6G75

Engine Mitsubishi 6G75 under the hood

The Mitsubishi 6G75 3.8-liter V6 engine was produced at the Kyoto plant from 2002 to 2021 and was installed on such popular concern models as the Endeavor, Pajero, Galant or Eclipse.

In 2002, the most voluminous engine of the Cyclone family debuted on the restyled Pajero 3. It was a completely ordinary V-shaped engine with a cast-iron block and a 60 ° camber angle, distributed fuel injection, intake swirl flaps, timing belt drive. It is the newest in the series, therefore it is significantly improved compared to its predecessors (for example, it received forged connecting rods). All versions of the unit had aluminum SOHC heads for 24 valves with hydraulic lifters.

In 2005, a more powerful version of the engine appeared with the proprietary MIVEC phase control system, and for a long time the company sold both modifications of this power unit in parallel. In the Japanese market, they offered a rare version of this engine with GDi direct fuel injection.

The 6G7 family also includes engines: 6G71, 6G72, 6G72TT, 6G73 and 6G74.

The engine was installed on:

  • Mitsubishi Eclipse 4 (DK) in 2005 – 2011;
  • Mitsubishi Endeavor 1 (D7) in 2003 – 2011;
  • Mitsubishi Galant 9 (DJ) in 2003 – 2009;
  • Mitsubishi Pajero 3 (V70) in 2002 – 2006;
  • Mitsubishi Pajero 4 (V90) in 2006 – 2021.

Disadvantages of the Mitsubishi 6G75 engine

  • Almost all versions of this engine are equipped with intake manifold swirl flaps, which tend to wedge, and then completely fall off and fall into the engine cylinders. Quite often, this ends up in expensive repairs and therefore it is advisable to remove them.
  • In engines up to 2009, the liners could turn even up to 100,000 km due to a drop in the performance of the oil pump or the pressure reducing valve wedge. Then the engine was upgraded and now this problem practically does not occur.
  • The weak points of this power unit include regular oil and antifreeze leaks, short-lived hydraulic lifters, sometimes they knock already at a range of 100-150 thousand km, as well as floating speed due to throttle contamination or burned-out lambda probes.
