Restore a secure, leak-free connection in your BMW’s cooling system with this replacement upper radiator coolant hose connector flange. This quick-connect fitting is designed to help properly seal the upper radiator hose connection and maintain consistent coolant flow through the cooling system.

Over time, factory plastic coolant connectors can become brittle from heat cycles, age, and pressure, leading to coolant leaks, loose hose connections, overheating concerns, or unexpected cooling system failure. Replacing a worn or damaged connector flange is an important step in keeping your BMW’s cooling system reliable.
