Product Description

The Cooltec Water Flange Heater Radiator is a crucial component within your vehicle’s cooling system, responsible for managing the flow of coolant between the engine, radiator, and heater core. This part helps maintain optimal engine temperature and ensures efficient cabin heating, contributing to overall engine performance and reliability. Constructed from durable plastic with a secure quick-connect design, it is designed to withstand the demands of daily driving.

This water flange is compatible with selected Audi, Seat, and Volkswagen models, including popular options like the VW Golf IV, V, VI and Audi A3 with 1.4TFSI and 2.0T engines. It is essential to confirm your vehicle’s model, year, engine size, and engine code before purchasing to ensure proper fitment.

Common symptoms of a failing water flange heater radiator include coolant leaks around the flange area, engine overheating, poor or inconsistent cabin heating, visible cracks or damage to the flange, low coolant levels without obvious external leaks, and warning lights for engine temperature. You may also notice a sweet smell from leaking coolant or steam from the engine bay.

If you observe any of these symptoms, it’s important to replace the water flange promptly to avoid engine overheating and potential damage. Replacement is typically needed when the flange becomes brittle, cracked, or is no longer sealing effectively against hoses or the engine block.
