403 180 3938 Compatible Oil Cooler Cover — Mercedes-Benz

What does an oil cooler cover do?

This oil cooler cover serves as a critical component in the engine cooling assembly, specifically designed to enclose the oil cooler housing. It holds the cooling core bundle securely in its seat on the engine block, ensuring that the internal cooling channels remain perfectly aligned and sealed under high pressure.

Vehicle and engine compatibility

This component is engineered for use in Mercedes-Benz O 303 vehicles featuring OM 401 engines. By maintaining a tight seal between the oil and coolant circuits, it prevents fluid mixing and protects the engine's thermal management system from failure.

Installation and maintenance

Installation requires careful attention to the sealing surfaces to prevent leaks during engine operation. This part is built with heavy-duty grade materials to withstand the thermal cycling and vibrations typical of heavy commercial vehicle engines. It is essential to verify that all sensor connections are properly seated during assembly.

System protection

Maintaining a secure cover helps prevent oil pressure drops and coolant contamination, which are vital for protecting crankshafts and bearings.
