85020085 Water Pump for Volvo FH Series

This water pump serves as a critical component within the engine cooling system, responsible for circulating coolant between the engine and the radiator. By maintaining consistent flow, it prevents overheating and protects engine longevity during long-haul operations or high-load conditions. These high-strength components are engineered to withstand the rigorous thermal stresses typical of heavy commercial vehicle engines.

This specific part is compatible with Volvo FH series engines, including models 440, 480, 500, 520, and the FH16 II series such as the 540, 550, 600, and 750 variants. It is also fitted to Volvo FH16 III models like the 550, 650, and 750. The pump is designed to meet the exacting requirements of these heavy-duty truck engines.

During routine maintenance or belt service, technicians should inspect this pump for signs of wear. Common indicators of failure include coolant leakage from the weep hole or unusual bearing noise. Replacing the pump alongside the timing or alternator belt is recommended to prevent sudden engine overheating due to impeller or seal failure.
