21228793 Water Pump for Volvo FH Series

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, responsible for the continuous circulation of coolant between the engine block and the radiator. By maintaining consistent thermal management, it prevents engine overheating and ensures optimal operating temperatures during heavy-duty service.

Compatible Volvo models

This component is specifically designed to fit various Volvo FH and FH II models, including the 440, 520, 480, 400, 500, 420, 460, 540, 380, and the LNG variants. It is engineered to meet the rigorous demands of heavy commercial vehicle engines used in transport and construction applications.

Installation and maintenance

For professional technicians, it is recommended to inspect the pump during routine belt or timing belt service. Monitoring for signs such as coolant leakage from the weep hole or unusual bearing noise can help prevent sudden system failure. Ensuring a secure fitment during installation is vital for maintaining pressure within the cooling circuit.

Troubleshooting tips

Consult your authorized distributor to ensure correct fitment for your specific engine configuration.
