Water pumps (pumps) are devices that pump coolant in a car engine, which remove excess accumulated heat from the cylinder block and supply hot liquid to the interior heater radiator. The pump stably and evenly maintains the temperature in different parts of the cooling system, evens out sharp temperature fluctuations and delivers the heat carrier to the heating radiator to warm up the entire car interior and to the main radiator of the cooling system.
Overheating of a car engine is one possible indicator of damage to the water pump. Among other reasons, engine overheating is often associated with a faulty water pump, a defective drive belt, or a damaged impeller.
Water pumps have been continuously improved over the years, however, due to the aggressive operating environment of the engine, the water pump usually has to be replaced during the life of the vehicle. Typically, seals and bearings, and ultimately the pump itself, fail prematurely due to the load on the drive belt, created by additional equipment or the tensioner when driven by the timing belt.
