85020085 Volvo FH Water Pump

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, facilitating the continuous circulation of coolant between the engine and the radiator. By maintaining steady fluid flow, it prevents overheating and ensures the engine operates within its ideal thermal range during intensive service cycles.

Compatible Volvo truck models

Designed specifically for heavy-duty applications, this part is compatible with Volvo FH models including the 400, 440, 480, 500, and 520 variants. It also fits various configurations of the Volvo FH16 II series, such as the FH 16/540, FH 16/600, and FH 16/750. This ensures high-performance cooling for these specific tractor units.

Installation and maintenance

When performing engine maintenance, it is recommended to inspect the pump alongside the timing belt or alternator belt service. Technicians should check for signs of failure such as coolant leakage from the weep hole or unusual bearing noise to prevent serious engine damage.

Troubleshooting and replacement

For optimal longevity, ensure all mounting surfaces are clean during installation. This component is built with high-strength materials to withstand high temperatures and vibrations common in heavy commercial vehicle operations.
