The water pump impeller is the rotating component inside the water pump that moves coolant through the machine's cooling circuit. Its vanes draw fluid in and push it outward under centrifugal force, maintaining a steady flow rate that keeps operating temperatures within safe limits. When an impeller wears, cracks, or loses a vane, coolant flow drops — leading to overheating, reduced performance, and potential damage to the engine or power unit it supports.
