Technical Characteristics of the Mercedes W207 OM642 Air Conditioning Compressor
The presented air conditioning compressor for Mercedes W207 with OM642 diesel engine belongs to the category of factory compressors used in premium vehicle air conditioning systems. The compressor's design is adapted to the loads generated by the diesel engine, ensuring stable refrigerant pressure across the full engine speed range.
A diesel engine's air conditioning system requires a properly selected compressor that can maintain correct operating parameters at both low and high RPMs. Using a dedicated compressor for the OM642 unit allows for:
- maintaining constant operating pressure in the air conditioning system,
- proper compressor lubrication and cooling under diesel engine operating conditions,
- stable operation of the compressor clutch during frequent system engagement and disengagement.
Application and Compatibility with OM642 Diesel Engine
The compressor is designed to work with the OM642 Diesel unit, meaning it is matched in terms of torque characteristics, rotational speed, and cabin cooling performance requirements. This ensures the compressor provides:
- consistency with the factory air conditioning system architecture in the Mercedes W207,
- adequate cooling performance for city and highway driving,
- maintenance of thermal comfort even under heavy diesel engine load.
Selecting a compressor dedicated to a specific fuel type reduces the risk of improper system operation, excessive vibrations, or accelerated wear of auxiliary components.
Category: Air Conditioning Compressors and Clutches
The offered part belongs to the Air Conditioning Compressors and Clutches category, meaning it is a key component responsible for compressing the refrigerant and interacting with the engine's auxiliary drive. A correctly selected compressor influences:
- stable operation of the entire air conditioning system,
- proper functioning of the compressor clutch and belt drive,
- reduction of mechanical loads transferred to the engine.

Practical Application and Installation Tips
The Mercedes W207 OM642 Diesel Air Conditioning Compressor is suitable for both standard replacement of a worn compressor and for a comprehensive air conditioning system overhaul after a failure. Before installation, it is recommended to:
- thoroughly flush the air conditioning system to remove contaminants and oil residues,
- replace the receiver-drier and check the expansion valve,
- perform a leak test and correctly fill the system with refrigerant according to the vehicle manufacturer's recommendations.
This approach minimizes the risk of repeat failures and allows for the full utilization of the installed compressor's potential in the Mercedes W207 OM642 diesel engine air conditioning system.
