The water pump plays a critical part in the function of your engine. It moves coolant flowing through the engine, radiator, and hoses to maintain the ideal operating temperature for your vehicle. Generally, the water pump’s 'powered by the serpentine belt and the crankshaft pulley. The water pump moves in a cycle. After leaving the engine it flows from the hoses to the radiator, cooled by the air movement from the radiator fins. Water then exits the radiator and enters the water pump once again completing the cycle. This entire process is put into action by centrifugal force and the impeller blade.
The water pump contains several seals and gaskets that keep coolant enclosed and secure as it flows throughout the engine. As these seals and gaskets age, they will become worn, cracked, and dried out. Once this occurs, the coolant can leak from the water pump. You may notice a green or occasionally red color pooling in the front of your car. This is the key indicator that you have a leaking water pump. If caught early a water pump can be repaired. If left unchecked a failing water pump can ruin your entire engine, so bring your vehicle to an ASE credited mechanic for an inspection!
