Wb 30x honda water pump

The water pump pushes coolant from the radiator through the coolant system, into the engine and back around to the radiator. The heat that the coolant picked up from the engine is transferred to the air at the radiator. The role of the water pump in an engine is primarily to regulate its temperature and to prevent the engine from overheating. It pumps water and coolant through the engine block and cylinder head (the main body of the engine) via a series of pipes, drawing out the heat generated, before going into a radiator. There are two major types of water pumps; centrifugal pumps and positive displacement pumps, each with its subcategories.
