Product Description
This Cooltec Water Flange Heater Radiator is designed for the cooling system of selected Audi and Volkswagen models. The water flange acts as a crucial connector, directing coolant flow between the engine, radiator, and heater system to maintain optimal operating temperatures. Its durable plastic housing features two hose outlets of different sizes and mounting tabs, ensuring a secure and leak-free fit in the engine bay.
It is compatible with various Audi and Volkswagen vehicles, including models with 1.4 TSI, TFSI, and 1.6 engines commonly found in the A3, Golf V and VI, Touran, Tiguan, and Caddy ranges. Always confirm your vehicle's model, year, engine size, and engine code to ensure correct fitment before ordering.
A faulty water flange can cause a range of issues, from coolant leaks to engine overheating and inconsistent cabin heating. Symptoms may include visible coolant loss around the flange, frequent low coolant warnings, engine temperature fluctuations, or reduced heater performance inside the vehicle.
Replacement is recommended if you notice cracks in the housing, damaged hose connections, or persistent coolant leaks near the flange area. Timely replacement helps prevent more serious engine damage due to overheating or coolant loss.
