G5,G6 Water Pump (Auxuliary)

Maintain proper coolant circulation and protect your engine from excessive heat with this replacement auxiliary electric water pump for a wide range of Volkswagen diesel models. This pump is used within the cooling water circuit to continue coolant flow through the engine, heater system, EGR cooler, or turbocharger cooling system when additional circulation is required.

Unlike the mechanically driven main water pump, this auxiliary pump operates electrically and can continue circulating coolant even after the engine has been switched off. This helps reduce heat soak on turbocharged diesel engines and improves overall cooling efficiency, heater performance, and engine temperature stability.

A failing auxiliary coolant pump can cause overheating warnings, poor cabin heater performance, intermittent coolant circulation faults, fault codes, or coolant system noises. Replacing a faulty pump helps restore correct coolant flow and can prevent damage to turbochargers and emission system components.

This pump is suitable for many VW diesel applications fitted with 1.6 TDI and 2.0 TDI engines across Golf, Passat, Tiguan, Caddy, Touran, Sharan and other popular models.
