Water Pump : A water pump is designed to circulate coolant / antifreeze to help regulate the temperature of the engine. Water pumps are driven either with a water pump belt, timing belt, timing chain or electronically. This crucial part of your vehicle’s cooling system can fail by leaking coolant, not spinning or making noise. What ever the problem with the water pump, the water pump must be replaced. Call Guy’s Automotive to have your water pump checked and or replaced today.
