Automotive Water Pumps

The water pump is an important element of the coolant system. It pumps the coolant from the reservoir and circulates it through the coolant lines. This keeps the engine cooled to the proper temperature so that overheating in not a danger. It is usually located at the front of the engine and is powered by an accessory drive belt or a pulley on the front end of the crankshaft. It circulates coolant from the lower radiator through the engine. It works by using a centrifugal action produced by an impeller on the pump shaft. When the water pump goes out the engine is in immediate danger of overheating. The warning light will indicate overheating and the car should be stopped immediately or it will be in danger of throwing a rod or causing other damage. The water pump is only one cause of overheating, so inspection is in order if overheating ever occurs. Water pumps can be easier to replace since they are at the front of the engine.
