Water Pump Pulley

If you have an internal combustion engine in your car or truck, most likely it is liquid cooled. This requires a pump to circulate fluid between the engine and the radiator to remove damaging heat. Unless the water pump has an electric motor, it requires a pulley that is driven by a belt connected to the engine crankshaft. The pulley water pump applications require can vary in diameter, belt type, and height.

When selecting a replacement water pump pulley, first confirm the year, make, model, and engine size of the vehicle. Then, from the remaining compatible options, choose the pulley that matches your application best, as well as your budget. For custom and performance applications, decide if you are using a v-belt or serpentine belt pulley system. Then select the correct pulley groove count, diameter, as well as the pulley to match the correct components for proper belt alignment (for example, small block Chevy with either a short or long water pump). Also available is a healthy water pump with pulley selection if water pump replacement is necessary.
