This is a 12-blade water pump impeller kit, a crucial component responsible for circulating coolant through the engine's cooling system. It is made from durable, corrosion-resistant rubber and metal, ensuring efficient fluid movement unlike a worn or damaged impeller with eroded or broken blades which reduces cooling capacity. Operators may notice the engine temperature gauge rising above normal or experiencing overheating issues when this kit 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 indication of a failing impeller is a rise in engine operating temperature, especially when the engine is under load. If left unaddressed, the reduced coolant circulation can lead to severe overheating, potentially causing cylinder head damage or gasket failure. Continued operation risks significant engine damage due to excessive heat.

Installation Tip

When replacing the impeller, carefully inspect the water pump housing for any signs of wear or damage, such as scoring or erosion. Ensure the new impeller is oriented correctly on the shaft.

Service Note

Inspect the engine thermostat and radiator for blockages or signs of corrosion when replacing the water pump impeller.
