7421814005 Water Pump for Renault Trucks K Series

What does a water pump do?

This water pump serves as a critical component within the engine cooling system, responsible for continuously circulating coolant between the engine block, cylinder head, and radiator. By maintaining consistent fluid flow, it prevents overheating and ensures the engine operates within its designed thermal range under heavy-duty conditions.

Vehicle and engine compatibility

This specific component is engineered for Renault Trucks K series vehicles, including the K440, K480, K520, and variants such as the 520T MEDIUM, 520T HEAVY, 520P MEDIUM, and 520P HEAVY. It is specifically compatible with DTI11 engines to provide reliable performance in heavy commercial vehicle applications.

Installation and maintenance

For optimal maintenance, it is recommended to inspect the pump during scheduled cooling system service. Technicians should check for signs of coolant leakage from the weep hole or unusual bearing noise. When replacing this unit, it is best practice to inspect associated belts or gaskets to ensure long-term system integrity.

Troubleshooting guidance

Maintaining a stable cooling temperature is vital for preventing engine wear and ensuring the longevity of the engine components.
