The function of an auxiliary water pump
An auxiliary water pump is different than a single water pump, because it is an electrically controlled motor. Its primary use is circulating water by way of a bypass hose from the main coolant lines to a heater core. The heater core is used to collect heat and distribute warm air into your vehicle when the heater is turned on. The main reason these pumps fail is age and wear of the electric motor.
