Your car or truck's engine relies on the continual circulation of coolant to keep the extreme temperatures your engine creates down to a controlled minimum. All of that combustion going on inside your engine's cylinders creates a serious amount of heat, and not all of it can be carried out via the exhaust. The most common answer was to envelope the engine in what is called a "water jacket," basically a series of passages that soak up all that hot heat and carry it away to the radiator where it will be whisked away into the air. The key element to all of this fluid circulation is the pump, called simply your water pump.
The water pump endures constant use inside an engine and allows the engine to endure the intense heat that internal combustion produces. When your engine is on, the water pump circulates coolant, or antifreeze, in the cylinder head and the engine block to cool the engine down. As such it requires maintenance just like every other part of your vehicle. Have the experts at Woodward Service Center do the maintenance you need.
