Fitment: Fits selected models across Audi and Volkswagen. Confirm exact fitment before ordering.
Product Description
The Cooltec Water Pump Auxiliary 3-Pin is designed to support the main cooling system by circulating coolant through critical engine components, especially during low-speed or idle conditions. This auxiliary water pump helps maintain optimal engine temperatures, preventing overheating and ensuring efficient operation in demanding driving situations.
This part is suitable for selected Audi and Volkswagen models, including popular variants like the VW Golf VII 2.0 GTI and Audi A3 1.8 TFSI, A4, and A5 2.0 TDI. Because fitment can vary based on model year, engine size, and engine code, we strongly recommend confirming these details for your vehicle before ordering.
Common signs that your auxiliary water pump may need replacement include irregular engine temperature, heater not working properly, coolant leaks near the pump, or unusual noises from the cooling system. In some cases, you may also notice warning lights on your dashboard or reduced performance of the climate control system.
When replacing this part, ensure that all electrical connections and hose fittings are secure. It is best to change the auxiliary water pump at the first sign of malfunction to avoid further damage to the cooling system or engine. Always check compatibility with your vehicle’s specifications before installation.
