Water Pump Impeller
Detroit Diesel

The water pump impeller is a key element in the engine’s cooling system, responsible for circulating coolant through the engine block and radiator. Its cast iron construction provides durability against corrosion and high operating temperatures. With a diameter of approximately 126 mm, the impeller generates sufficient flow to prevent engine overheating, especially during prolonged or intensive workloads. The precise width of 26.5 mm ensures efficient fluid movement without excessive turbulence. Proper functioning of this component is vital for maintaining engine temperature within optimal ranges, thereby preventing thermal damage. Regular inspection for corrosion, damage, or imbalance is recommended for sustained performance. Replacing a worn or damaged impeller promptly can prevent engine overheating and subsequent costly repairs.
