The part is compatible with several Volvo truck models including the FH series, FM series, and FL series, as well as Renault Trucks Magnum. It is specifically designed for use with engines such as the D12C, D16C, TD102, and TD123 to ensure precise thermal management. This component is also fitted to Volvo VHD and VNL models featuring D12 engines.

Installation and maintenance

For proper maintenance, workshop technicians should inspect the housing and its sealing surfaces during routine cooling system service to prevent leaks or temperature fluctuations. Ensuring a secure fitment within the coolant line between the engine block and radiator is essential for maintaining system pressure.
