7420734268 MAGNUM Renault Trucks DXi Engine Water Pump

What does a water pump do?

This water pump plays a vital role in the engine cooling system by ensuring the continuous circulation of coolant between the engine block and the radiator. By maintaining consistent thermal management, it helps prevent engine overheating and protects high-strength components from thermal stress during long-haul operations.

Vehicle and engine compatibility

This specific unit is compatible with Renault Trucks MAGNUM models, including variants such as the 440.19, 440.24, 440.26, 480.18, 480.24, and 480.26, specifically designed for DXi engines. It provides a reliable solution for fleet managers and workshop technicians looking to maintain heavy commercial vehicle performance.

Installation and maintenance

For optimal performance, technicians should inspect the pump during belt service intervals. Monitoring for signs such as coolant leaks from the weep hole or unusual bearing noise can help prevent sudden engine failure. Ensure all connection points are torqued to specification during installation.
