Pumps were made to move liquids and the earliest reference to them can be found in the writings of Archimedes way back in the third century. You’ll find that pumps come in various sizes and shapes and they work by means of mechanical energy which either lifts material or pushes it using compression.
The water pump in a car is there to cool the engine and it is a very important part of an automotive system because without it, the engine will get overheated. The crankshaft has a belt connected to it and this belt drives the centrifugal water pump.
The pump helps to move the coolant into the engine from the radiator and back again. On one end of the pump is the rotor, on the other is a shaft with a pulley. When the pulley starts to spin, the rotor begins releasing the coolant and the pump circulates it. Most pumps have a rotating impeller and this is responsible for circulating the coolant through the engine.
The pump operates with centrifugal force which shoots out coolant to the outside drawing fluid up from the center where the fluid coming back from the radiator comes in through an inlet.
If you want your engine to maintain its temperature at the desired levels and not get overheated, it is important to make sure that your water pump is working well. The better the circulating capacity, the better will be the temperature control in your car.
It’s best to check your water pump regularly so that you don’t have the hassles that an overheated vehicle can bring, like blown head gaskets, heads that warp and a whole lot of wear and tear on your vehicle. Signs that it needs replacing could be a noise or maybe even coolant leaking.
Considering that the pump is really the heart of the cooling system in your car, it pays to make sure that it gets replaced when necessary
