A water pump is a part of the vehicle which allows coolant to travel from the radiator to the engine. It lets the fluid absorb the heat as the vehicle speeds up and it is generally installed with the radiator and cooling fan.
Water pump principlesThe water pump is a vital component of the circulation of coolant that travels around the engine and to the radiator. A belt from the crankshaft controls the water pump, but modern cars come with an electric water pump. Water pumps that are run by a timing belt are attached to the engine block. To keep any damage or debris away from the timing belt it has a protective cover.
Modern-day water pumps are cast out of aluminum, and it is accompanied by a shaft that rotates on bearings while the pulley and impeller transfer the coolant. To prevent any coolant from accessing the bearing and shaft, a seal is placed on the shaft.
Common issues with a bad water pumpA bad water pump can cause coolant leaks and noises. Additionally, the vehicle will be more susceptible to overheating.
