Product Description

The Arrowhead Water Flange Head is a crucial component in your BMW's cooling system, responsible for securely routing coolant between the engine and associated hoses. This part helps maintain optimal engine temperature by ensuring a proper seal and flow path, preventing leaks and overheating. Its robust plastic construction and reinforced design make it suitable for the demands of daily driving and long-distance travel.

This water flange head is specifically designed for select BMW models, including the E90 330d (2004 to 2011) and the 5 Series F10 525d and 530d (2009 to 2016). Always confirm your vehicle’s model, year, engine size, and engine code before purchasing to ensure correct fitment.

Common symptoms of a failing water flange head include coolant leaks near the flange area, low coolant warnings, engine overheating, visible cracks or damage to the flange, and erratic temperature gauge readings. You may also notice steam from under the bonnet or a sweet smell from leaking coolant.

Replace the water flange head if you observe any signs of cracking, warping, or coolant seepage. It is also advisable to replace this part during major cooling system overhauls or when performing routine maintenance on high-mileage vehicles to prevent unexpected breakdowns.
