403 180 39 38S Mercedes-Benz OM 401 Oil Cooler Cover

What does an oil cooler cover do?

This oil cooler cover plays a vital role in the engine's thermal management system by enclosing the oil cooler housing and securing the cooling core bundle. By maintaining a precise seal between the oil and coolant circuits, it prevents fluid mixing and ensures that engine oil remains at optimal operating temperatures, protecting critical internal engine components.

Vehicle and engine compatibility

This specific part is engineered for Mercedes-Benz O 303 trucks featuring the OM 401 engine. It serves as a reliable replacement for the original housing component, ensuring the integrity of the oil transfer channels under heavy-duty operating conditions.

Installation and maintenance

When performing maintenance or engine overhauls, technicians should inspect the sealing surfaces and sensor connection points for any signs of wear or deformation. Proper installation is essential to maintain the pressure requirements of the lubrication system and to prevent leaks between the cooling and lubrication circuits.

Reliability and selection

Selecting an OE-equivalent part ensures that all mounting points and sensor interfaces align perfectly with the existing engine block configuration, maintaining the long-term reliability of the cooling assembly.
