Fitment: Fits selected models across Audi, Seat, and Volkswagen. Confirm exact fitment before ordering.
Product Description
Ensure your Audi, Volkswagen, or Seat’s cooling system operates efficiently with the Arrowhead Water Flange Heater Radiator. This crucial cooling water flange connects radiator hoses and heater pipes, directing coolant flow between the engine, radiator, and heater core. Its robust plastic construction and integrated locking features are designed for a secure fit in modern diesel engines.
This water flange is compatible with select Audi, Volkswagen, and Seat models, especially those equipped with 1.6, 1.9, and 2.0 TDI engines. It is commonly found in models such as the Audi A3, VW Golf V, Touran, and Caddy. Always confirm your vehicle’s model, year, engine size, and engine code before placing your order to ensure a perfect fit.
A failing water flange can lead to a range of cooling issues. Typical symptoms include coolant leaks around hose connections, visible cracks or warping on the flange, fluctuating engine temperature, low coolant warnings, poor heater performance, and frequent overheating. You may also notice the smell of coolant or visible steam from the engine bay.
Replacement is recommended if you observe leaks, cracks, or if the flange’s hose connections become loose. Regular inspection during coolant service can help catch issues early and prevent more serious engine damage.
