2820683-2845561-1095324 Water Pump Impeller — Cat 3176B 3176C

This water pump impeller is a crucial component within the engine's cooling system, responsible for circulating coolant to prevent overheating. Manufactured to high standards, it ensures efficient fluid movement, unlike a worn impeller with eroded or broken vanes that cannot effectively pump coolant. Operators might observe a rising engine temperature gauge, steam from the engine bay, or a noticeable decrease in heating system performance when this part fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing water pump impeller is often a gradual increase in engine operating temperature, indicated by the temperature gauge. If left unaddressed, the engine can quickly overheat, leading to potential damage to the cylinder head, gaskets, and other critical components. In severe cases, this can result in engine seizure.

Installation Tip

Ensure the water pump housing and shaft are clean and free of corrosion before installing the new impeller. Do not attempt to force the impeller onto the shaft; it should fit snugly but without excessive force.

Service Note

Inspect the water pump seal, bearings, and the entire cooling system (radiator, hoses, thermostat) for leaks or blockages when replacing the impeller.
