85000956 Volvo FH III Water Pump

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, ensuring the continuous circulation of coolant between the engine block and the radiator. By maintaining steady fluid flow, it prevents overheating and protects engine components under heavy-duty operating conditions. This part is manufactured using high-strength components to withstand the thermal and mechanical stresses found in heavy commercial vehicle environments.

Compatible Volvo truck models

This component is specifically designed for a wide range of Volvo trucks, including FH III models such as the 460 AERO, 540 AERO, 460 LNG, and 500 AERO LNG, as well as various FH II and standard FH variants like the 420, 460, 500, and 540. It is also compatible with other Volvo FH series engine configurations to ensure precise fitment across different truck specifications.

Installation and maintenance guidance

For optimal performance, technicians should inspect the pump during routine cooling system maintenance or when replacing belts. Signs of wear include coolant leakage from the weep hole or unusual bearing noise. When performing repairs, it is recommended to check all related hoses and seals to ensure a leak-free installation.

Troubleshooting and selection

Selecting a high-quality replacement ensures that the thermal regulation of the engine remains stable during long-haul operations. Consult your authorized distributor to confirm exact compatibility with your specific engine code.
