Engine Overview and Common Failures
The weight of the VK45DE engine is 230 kg (without accessories). The engine number VK45DE is located at the junction with the gearbox. There are scratches and oil consumption issues. If the oil level is neglected, the bearings will rotate. The timing chain stretch depends heavily on the operation mode and can stretch up to 150,000 km for excessively active owners. The replacement procedure is quite expensive as the entire front of the car needs to be disassembled. It is recommended to carefully monitor the cooling system of the engine, not only the cleanliness of the radiator but also the condition of the unreliable fan viscous coupling. This engine does not tolerate overheating: it immediately blows the gasket or damages the cylinder head. Many modifications of this engine are equipped with intake manifold with flaps, the bolts of which have a tendency to unscrew and fly straight into the combustion chambers. It is highly desirable to disassemble the manifold and secure the troublesome bolts with sealant. Other problems that can be found online include difficult starting in winter, lambda sensors frequently burning out from low-quality fuel, and an unreliable fuel pump in the tank. Don't forget about adjusting the valve clearance, as there are no hydraulic lifters here.
