Without a functional water pump, your Chevy will have to sit. The water pump is directly responsible for circulating the coolant throughout the engine. If the water pump is not operating correctly, the engine will overheat. If you do not repair it in a timely manner, the problems will only get worse, and the repairs become more expensive including head gasket failure and the engine potentially seizing. It is not necessary to take your car to the repair shop, because this is a project that you can do yourself.
