3803909 Compatible Water Pump — Volvo FH12

This water pump plays a critical role in the engine cooling system by continuously circulating coolant between the engine block, cylinder head, and radiator. It is engineered to maintain optimal thermal management, preventing engine overheating during intensive operations in heavy commercial vehicles.

This component is specifically compatible with Volvo FH12 models, including the FH 12/340, FH 12/380, FH 12/420, FH 12/500, FH 12/460, FH 12/390, and FH 12/430 variants. It serves as a high-durability alternative for original equipment requirements in these specific truck engines.

For optimal performance, technicians should inspect the pump during routine belt service. It is recommended to check for signs of leakage from the weep hole or unusual bearing noise during maintenance intervals. Replacing the pump alongside the timing or alternator belt is a recommended practice to ensure system integrity.

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