Mercedes W204 C207 Oil Filter Housing Cooler OM651 A6511800810

Mercedes W204 C207 Oil Filter Housing Cooler OM651 is a factory-original component of the lubrication and oil cooling system, designed specifically for OM651 power units. Integrating the filter housing with the oil cooler ensures stable engine operating conditions and facilitates maintenance by reducing the number of connections and potential leak points. This solution helps maintain the proper oil temperature even under heavy loads.

Function and role in the OM651 lubrication system

The oil filter housing integrated with the cooler is responsible for directing oil through the filter element and for its effective cooling within the OM651 engine circuit. A properly functioning module:

• stabilizes oil temperature across a wide range of engine loads,
• ensures proper flow through the filter element,
• reduces the risk of oil pressure drops resulting from leaks,
• supports the durability of bearings, the turbocharger, and other lubricated components. Thanks to its compact modular design, this lubrication system component is particularly important in diesel engines, where stable oil cooling has a direct impact on the service life of the power unit.

Compatibility and part identification

The presented oil filter housing with cooler is intended for use in Mercedes C-Class W204 and C207 models with the OM651 engine. Identification is based on the OEM part number and related interchangeable numbers, which are listed in the technical specifications section. This allows for precise matching of the component to the specific engine version and model year of the vehicle. Before purchasing, it is recommended to compare the markings with the currently installed module to ensure full compatibility with the lubrication and cooling system of your specific car.

Benefits of using an original oil filter housing

Using an original oil filter housing with cooler in an OM651 engine provides a number of practical operational benefits:

• Factory fitment for threads, connectors, and oil channels in the engine block,
• preservation of the oil flow and cooling parameters designed by the manufacturer,
• reduced risk of leaks at oil and coolant line connections,
• easier maintenance when replacing the oil filter element. For OM651 units, known for their high efficiency and high mileage, a properly functioning oil filter housing module with cooler is an important element in preventing premature engine wear.

Condition and service application

The offered oil filter housing with cooler comes from a Mercedes vehicle and is a component in the Oil filters category. It can be used both for standard replacement of a damaged module and during major service work related to the lubrication system, e.g., after engine overheating or when oil leaks are detected in the housing area. Before installation, it is recommended to thoroughly clean the mating surfaces, use new gaskets, and check the oil cooling system for blockages. This approach allows you to fully utilize the potential of the part and ensure stable operation of the lubrication system after the repair is completed. If you are planning a comprehensive repair or upgrade of the engine area in your Mercedes and need other components from the same group, such as oil filter elements, filter bases, or filter modules, check the available parts in the Mercedes oil filters category.
