Product Description

This Cooltec Water Flange Rad to Exp Tank is designed for BMW cooling systems, specifically serving as the critical junction between the radiator and the expansion tank. It ensures proper coolant flow and helps maintain optimal engine temperature by securely routing coolant through the necessary pathways. The water flange features multiple hose connections and mounting points, which are essential for a leak-free and stable installation in your BMW.

This part is compatible with BMW models, and is commonly found in vehicles such as the E46 petrol series. Always check your vehicle’s model, year, engine size, and engine code to confirm compatibility before placing your order.

Typical symptoms of a failing water flange include coolant leaks around the flange area, visible cracks or damage to the plastic housing, overheating engine, low coolant warnings, steam from the engine bay, or frequent need to top up coolant. You may also notice poor heater performance or erratic temperature gauge readings.

It is recommended to replace the water flange if you observe any leaks, cracks, or if you are carrying out a cooling system overhaul. Timely replacement helps prevent engine overheating and possible severe engine damage.
