Water pump pulley: the silent killer that can destroy your engine (and wallet)
What To Know
- A water pump pulley is a small, round pulley that is attached to the crankshaft of your engine.
- It is connected to the water pump by a belt, which drives the water pump when the engine is running.
- The serpentine belt drives the water pump pulley, so it is important to replace it regularly to prevent it from slipping and damaging the water pump pulley.
Your water pump pulley is a critical component of your vehicle’s cooling system. It helps to drive the water pump, which circulates coolant throughout the engine to keep it from overheating. Without a properly functioning water pump pulley, your engine could quickly overheat and cause serious damage.

Why Is a Water Pump Pulley Important?
The water pump pulley is important because it helps to drive the water pump, which circulates coolant throughout the engine. Coolant is a liquid that helps to absorb heat from the engine and carry it away to the radiator, where it can be cooled down. Without a properly functioning water pump pulley, the coolant would not be able to circulate properly, and the engine would quickly overheat.
