403 180 3938 Oil Cooler Cover for Mercedes-Benz MK

What does an oil cooler cover do?

This engine oil cooler cover plays a critical role in maintaining the thermal stability of the engine's lubrication system. By enclosing the oil cooler housing, it holds the cooling core bundle securely in its seat, ensuring that engine oil and coolant remain in separate, controlled circuits. This component is essential for preventing fluid mixing and maintaining optimal oil temperature under heavy-duty operating conditions.

Vehicle and engine compatibility

Specifically designed for Mercedes-Benz MK 1831 K trucks equipped with OM 402 LA engines, this part ensures precise fitment. It is engineered to withstand high pressure and thermal cycling, making it a reliable choice for workshop technicians performing engine overhauls or cooling system repairs. This part is compatible with Mercedes-Benz OE specifications.

Installation and maintenance

During installation, technicians should carefully inspect the sealing surfaces to ensure a leak-free connection between the cover and the engine block. Proper torque application is vital to prevent housing deformation. As this unit includes a sensor connection, ensure that all electrical connections are secure and the sensor is properly seated to avoid diagnostic errors.

Troubleshooting and selection

Regular inspection of the oil cooler assembly can help prevent overheating or oil contamination issues. If leaks are detected near the cooling core, replacing the cover can resolve sealing failures caused by thermal stress or debris buildup. Consult your authorized distributor to check the compatibility list.
