Cummins Water Pumps

What does the water pump do?

The water pump in your Cummins diesel engine is designed to push coolant from the radiator through the entire coolant system. The engine's coolant travels from the engine to the radiator where the temperature of the fluid is reduced by the air passing over the radiator.

Your internal combustion engine generates a vast amount of heat. To offset the heat output produced by friction and combustions in the engine, a water pump is used to pump coolant throughout tubes and passages in the block, flowing around the sides of the cylinder walls and liner. The water pump pushes the heated coolant to the radiator where it is then dissipated.

The engine heat that the coolant has absorbed is pushed to the radiator by the engine's water pump. This heated coolant then releases the temperature using the radiator as the heat transfer vessel. Without the water pump functioning properly, the coolant sits in the system. The engine is likely to overheat, which can cause severe engine damage. Your engine's Water Pump is considered a wear item which has a limited lifespan. The Water Pump in your Cummins diesel engine should be inspected and or replaced at the recommended service interval.
