This is a water pump assembly responsible for circulating coolant through the engine block and radiator to maintain optimal operating temperatures in Volvo excavators and wheel loaders. It is built to OEM standards, ensuring efficient heat transfer and longevity over a worn or seized unit. Operators may observe a rising temperature gauge, steam from the engine compartment, or coolant leaks when this component fails.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a failing water pump is often a noticeable coolant leak from the weep hole or a whining noise from the pulley bearing. If left unaddressed, the pump can seize or its impeller can erode, leading to rapid engine overheating and potential internal damage. Continued operation with an overheating engine can cause severe damage to cylinder heads, gaskets, and pistons.
Thoroughly clean the engine block mounting surface to ensure a perfect seal and prevent leaks. Do not reuse the old water pump gasket; always install a new one with the correct sealant if recommended.
When replacing the water pump, inspect the drive belt, tensioner, and thermostat for wear or proper function.
