Product Description

This Cooltec WATER FLANGE RAD TO EXP TANK is a crucial component in your BMW's cooling system, connecting the radiator to the expansion tank and ensuring smooth coolant flow. Designed specifically for BMW models, it features a robust plastic construction with multiple hose ports and integrated mounting flanges for secure installation. The water flange helps regulate engine temperature by directing coolant between key components, preventing overheating and maintaining optimal engine performance.

This part is compatible with select BMW models, including E46 320d and 330d, E83 2.5i and 3.0i, as well as E85 and E86 variants. It is important to confirm your BMW's model, year, engine size, and engine code before ordering, as cooling system configurations may vary.

Common symptoms of a failing water flange include coolant leaks near the flange, visible cracks or warping on the component, frequent low coolant warnings, engine overheating, erratic temperature gauge readings, and coolant odours in the engine bay. Addressing these issues promptly can help prevent more serious engine damage.

Replacing a worn or damaged water flange is essential when you notice leaks, signs of wear, or after high mileage. Always inspect all connecting hoses and seals during replacement to ensure a proper, long-lasting repair.
