OEM GM Water Pumps
In order to keep the water circulating between the radiator and the engine, the water pump is called into duty. It sends cooled water from the radiator into the engine where it will become heated and sent back through the system again.
The water pump is driven by a belt, and it is a centrifugal pump. The water only circulates when the engine is running because the belt that drives it is driven by the engine itself. The pump spins and draws water out as it moves, and then it sends the water into the engine block. It is situated by the radiator.
Every engine is different when it comes to how much water it needs or how fast it needs it, so you want a genuine OEM GM part that is specifically built for your vehicle. A Rendezvous, a Cruze, and a Tahoe may all have very different specifications, so the part you get must fit your exact vehicle. Genuine OEM parts do not need to be modified to fit.
Water pumps are one of those parts that last a long time but will likely need to be replaced during the ownership of your vehicle. If you live somewhere that is particularly hot or extremely cold, you may need to replace yours sooner than normal due to extreme conditions.
