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

This engine oil cooler cover plays a vital role in the engine's thermal management system by enclosing the oil cooler housing. It secures the cooling core bundle within its seat on the engine block, ensuring that engine oil and coolant remain in separate, controlled circuits. By maintaining this separation, the component prevents critical fluid contamination and helps regulate engine temperatures during heavy-duty operation.

This specific part is designed for Mercedes-Benz O 303 trucks and buses powered by the OM 402 engine. It is engineered to match the specific sealing surfaces and bolt load requirements of the original assembly, ensuring a reliable fit for the vehicle's cooling architecture.

When performing maintenance or repairs, technicians should inspect the sealing surfaces of the cover to prevent leaks between the oil and coolant channels. Proper torque application during installation is essential to maintain the integrity of the seal under high pressure. For optimal performance, ensure that all connection points, including sensor interfaces, are clean and free of debris before assembly.
