This is a Coolant Pump, a vital component of the engine's cooling system in Volvo trucks. It circulates coolant through the engine block and radiator, dissipating heat to maintain optimal operating temperature. Manufactured to high standards, it ensures efficient fluid flow and prevents overheating, unlike a worn pump that can lead to reduced circulation and engine damage. Operators may notice the engine temperature gauge rising above normal, steam from the engine bay, or a significant loss of coolant when this pump fails.
Always verify with serial number before ordering.

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 initial symptom of a failing coolant pump is often a higher-than-normal engine operating temperature indicated by the temperature gauge. If ignored, this can lead to reduced cooling efficiency, potential engine damage due to overheating, and coolant leaks from the pump seal or housing.
Ensure the engine is completely cool before draining the coolant and removing the old pump. Always use a new gasket or sealant as specified and torque the mounting bolts evenly in a star pattern.
Inspect the drive belt for wear and tension, and flush the cooling system thoroughly before installing the new pump.
