What is a water pump

The water pump is the heart of the cooling system and is responsible for circulating coolant, consisting of housing (aluminum diecast, cast iron, aluminum gravity etc), flange(forged steel, sintered iron etc), impeller (pressed steel, cast iron, synthetic resin etc), water pump bearing and mechanical seal kit.

Water pumps’ material is depending on performance level, quality as well as customer requirements and working conditions.

Water pump circulates coolant between the engine and radiator to keep the engine from overheating. Inside the water pump is a metal or plastic impeller with blades that push the water through the pump. The impeller is mounted on a shaft that is supported by the pump housing with a bearing and seal assembly. The cooling liquid absorbs the heat from the engine block and cylinder head and releases it into the ambient air through the radiator.

The water pump is usually driven by V-belts or poly-rib belts depending on their installation location in the engine. It’s mounted on the engine block from the outside and can be replaced without having to open the engine itself.

Water Pump critical quality

When water pumps fail, the engine overheats, which can result in serious engine damage. Water pumps are typical wear parts, which must sometimes be replaced several times during the service life of the engine.

Water pumps typically fail one of two ways: the shaft seal starts to leak, or the impeller inside breaks, comes loose or the blades erode and wear down (which is more of a problem with pumps that have plastic impellers).

When a water pump starts to leak, the cooling system will lose coolant. If the leak is not discovered, the loss of coolant will eventually cause the engine to overheat. The drive may not realize anything is wrong until the temperature warning light comes on. If this happens to you, shut the engine off immediately. Severe engine damage can result if an overheating engine is driven too far.

If the engine has overheated, the entire cooling system (radiator, hoses, water pump and engine) must all be inspected to see if there are any coolant leaks. If coolant is leaking out of the water pump shaft or vent hole, the water pump needs to be replaced. Cooling system sealer cannot stop this kind of leak.
