T5 Water Pump (Auxiliary)

Replacement electric auxiliary water pump for the cooling system fitted to a wide range of VW T5 Transporter, Multivan and California models. This pump helps circulate coolant independently of engine speed, improving coolant flow through the heating and cooling circuits during specific operating conditions.

Auxiliary water pumps are commonly used to support cabin heater performance, turbocharger cooling and coolant circulation after engine shutdown. On many T5 applications, the pump continues circulating coolant after the engine is switched off to help stabilise temperatures and reduce heat soak within the engine and turbo system.

A failing auxiliary pump can cause poor heater performance, overheating issues, coolant circulation faults or fault codes within the cooling system. Common symptoms include intermittent cabin heating, noisy operation or coolant circulation warnings.

This is a 12V electrically operated unit with a 2-pin connector, designed as a direct replacement for the original factory-installed pump.
