21814009 Volvo FH Water Pump D16K Engine

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 consistent thermal management, it prevents overheating and protects heavy-duty engine components from thermal stress during long-haul operations.

Vehicle and engine compatibility

This specific unit is designed for compatibility with Volvo FH models (including 420, 460, 500, and 540 variants) and Volvo FH16 engines equipped with the D16K engine code. It is engineered to withstand the high temperatures and vibrations typical of heavy commercial vehicle service.

Maintenance and inspection

For optimal performance, technicians should inspect the pump during routine timing belt or alternator belt service intervals. It is recommended to check for signs of coolant leakage from the weep hole or unusual bearing noise to ensure the integrity of the cooling circuit.

Preventing engine overheating

Maintaining a functional water pump is essential for preventing serious engine damage caused by overheating. Consult your authorized distributor to ensure exact fitment for your specific engine configuration.
