109-5324-18000k 12 Blade Water Pump Impeller — Cat 3176B 3406E

This is a 12-blade water pump impeller, the rotating component that circulates coolant through the engine block and radiator to maintain optimal operating temperature. Manufactured to meet stringent OEM quality standards, it ensures efficient heat transfer unlike a worn impeller with damaged or corroded blades. Symptoms of a failing impeller include engine overheating, a lack of coolant circulation, and potential steam from the engine compartment.

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 impeller is often a gradual increase in engine coolant temperature, especially under load. If ignored, this can lead to insufficient coolant circulation, causing the engine to overheat severely and potentially leading to component damage. Prolonged operation with a compromised impeller risks catastrophic engine failure due to excessive heat.

Installation Tip

Ensure the impeller shaft and housing are clean and free of corrosion before installation. Do not force the impeller onto the shaft; it should slide on smoothly.

Service Note

Inspect the water pump seal and gasket for leaks, and check the condition of the thermostat when replacing the impeller.
