The weight of the G6CT engine according to the catalog is 191.9 kg. The engine number G6CT is located in the front, at the junction of the engine and the gearbox. In the early years, the assembly quality of the engines and some of their components was very poor. Many cases have been described where the engine seized due to the rotation of the bearings at 50,000 km. Then the quality improved and now most complaints are related to oil consumption. It is also common for the RPM to fluctuate due to throttle, injector, or ECU contamination. The ignition system and short-lived hydraulic lifters are considered weak points.
