403 180 39 38S Compatible Oil Cooler Cover — Mercedes-Benz

What does an oil cooler cover do?

This oil cooler cover plays a critical role in maintaining the thermal stability of the engine oil system. It is engineered to enclose the oil cooler housing, ensuring the cooling core bundle remains securely seated and sealed within its position on the engine block. By maintaining these strict boundaries, it prevents the mixing of engine oil and coolant circuits.

Compatible vehicles and engines

This specific component is designed for Mercedes-Benz MK models equipped with OM 401 LA engines, including variants such as the 2531, 2524, 1831, and 1827 series. It is suitable for various configurations including tractor units and heavy trucks. The part is built to withstand the high thermal and mechanical stresses encountered in heavy commercial vehicle operations.

Installation and maintenance

Installation requires precise alignment to ensure the sealing surfaces are perfectly seated against the cooling core. Technicians should verify that the sensor port is in correct condition to allow for accurate monitoring of system pressures or temperatures. Proper torque application during mounting is essential to prevent leaks between the oil and coolant channels.

Troubleshooting and selection

Regular inspections of the cover and its seals can help prevent overheating or oil contamination issues. When replacing this component, ensure the mounting surfaces are clean and free of debris to maintain a high-strength seal under operating pressure.
