An auxiliary electric water pump is a cooling system component designed to circulate coolant independently of engine speed. It maintains stable engine temperature, supports cabin heating, and ensures proper cooling of the turbocharger after engine shutdown.
The electric pump is installed in the cooling circuit and works together with the main water pump, radiator, thermostat, engine control unit, heater core, and turbocharging system.
A faulty auxiliary pump may cause engine overheating, weak cabin heating, cooling system warnings, increased temperature after engine shutdown, or abnormal noise.
Our catalog includes auxiliary electric water pumps for many vehicle brands. Available options include genuine factory cooling system components, reliable aftermarket replacements, and tested used pumps without housing or impeller damage. Solutions for petrol and diesel engines, turbocharged models, and hybrid systems are available.
Used parts are inspected for sealing integrity, electric motor performance, connector condition, absence of excessive play, and wear.
Selection is available by VIN number, engine code, part number, and vehicle year. Replacing a faulty auxiliary pump restores proper coolant circulation and cooling system efficiency.
