The 4G69 engine was the final model in Mitsubishi’s renowned Sirius series. It made its debut in 2003, and even though the Japanese automaker changed the engine for a more contemporary one two years later, production continued.
The engines 4G61, 4G62, 4G63, 4G63T, 4G64, and 4G67 are also part of the 4G6 family.
Initially, only the Grandis, Outlander, and Galant models of the company had this motor installed. The in-line 4-cylinder 2.4-liter engine and its parts are still being produced under license in China today.
The average fuel consumption of 4g69 is not more than 9.5 liters per 100 kilometers, even with the working volume of 2.4 liters.
Additionally, a version with direct fuel injection GDI was created; in these engines, the compression ratio was raised to 11.5.

Disadvantages of the Mitsubishi 4G69 engine
Unreliable belts are the primary issue here, as they are with all engines in this series;
The timing belt may become trapped beneath the balance shaft belt if it suddenly breaks;
This causes the timing belt to break and the valves to bend at high engine speeds;
Additionally unreliable are the drive of mounted units and the tension roller;
This location lacks hydraulic lifters, and valve clearances must be changed every 50,000 kilometers.
