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

What does an oil cooler cover do?

This oil cooler cover functions as a critical component within the engine cooling system, specifically designed to enclose the oil cooler housing. By holding the cooling core bundle securely in its seat, it maintains the necessary seal between the engine oil and coolant circuits. This prevents fluid mixing and ensures that heat exchange occurs efficiently to protect internal engine components.

Compatible Mercedes-Benz engines

The part is specifically fitted to Mercedes-Benz OH 1628, 1628 L, 1625, and 1625 L trucks equipped with OM 422 engines. This ensures precise fitment for heavy commercial vehicle applications where thermal stability is required. It serves as a reliable replacement for worn or damaged covers in these specific engine configurations.

Installation and maintenance

During installation, technicians should ensure that all sealing surfaces are clean and free of debris to maintain pressure integrity. Because this unit manages critical fluid channels, verifying the sensor compatibility—such as the OK sensor status—is essential for accurate engine monitoring. Proper torque application on mounting bolts is vital to prevent leaks under high thermal loads.
