A4031803938S Oil Cooler Cover for Mercedes-Benz SK

What does an oil cooler cover do?

This oil cooler cover serves as a critical sealing component within the engine cooling system of heavy commercial vehicles. It is engineered to enclose the oil cooler housing, ensuring that the cooling core bundle remains securely seated against the engine block. By maintaining a precise seal, it prevents the mixing of oil and coolant, which is vital for engine longevity and performance.

Vehicle and engine compatibility

This specific part is designed for Mercedes-Benz SK series vehicles, including models such as the 2031 S, 2024 K, 1831 L, and 2631 K. It is specifically engineered for use with the OM 401 LA engine. This ensures that the oil transfer channels and sealing surfaces meet the required tolerances for heavy-duty operation.

Installation and maintenance guidance

For workshop technicians, proper installation is essential to prevent leaks between the lubrication and cooling circuits. When replacing this component, ensure all surfaces are clean and that the sensor connection is properly seated to avoid pressure drops or monitoring errors. Maintaining correct torque on the mounting bolts is necessary to ensure a stable seal under high thermal loads.

System integrity and troubleshooting

Always verify compatibility with the specific engine series before installation to ensure optimal system performance and prevent potential fluid contamination within the cooling system.
