525.03.0009 Compatible Water Pump — Volvo and Renault Trucks

What does a water pump do?

A water pump is a critical component of the engine cooling system, responsible for circulating coolant between the engine and the radiator to maintain optimal operating temperatures. In heavy-duty trucks, this component must withstand high heat and pressure to prevent engine overheating during long-haul operations or under heavy loads.

Compatible vehicles and engines

This water pump is compatible with a wide range of Volvo models including FM, FMX, FH, and VNL series, as well as Renault Trucks models such as Premium, Kerax, T-series, and D-series. It is designed to fit specific engine configurations including D13K, D11K, DTI13, DTI11, and DXi series engines.

Installation and maintenance

For optimal performance, technicians should inspect the pump during routine belt services. Check for signs of coolant leakage from the weep hole or unusual bearing noise. Replacing this component helps prevent serious engine damage caused by thermal fluctuations.
