Specifically designed for the cylinder head to thermostat hose on N5X and N2X engines, known popularly as the "mickey mouse flange", this revised aluminum replacement addresses the common failure of OE style plastic flanges, includes sealing o-ring and hose clamp for complete installation

The plastic flange includes with the coolant hose which connects the thermostat to the cylinder head is extremely failure prone. This flange is known to break on it's own during normal vehicle operation. However, it's also known to break when replacing the hose assembly as a whole as regular maintenance.

Up until the introduction of this aluminum flange from Rein, it would have required replacement of the entire hose to replace the broken fitting. Now you can replace the flange with a failure proof replacement.

FCP Euro recommends replacing this flange as preventative maintenance. There is no known mileage as to when the plastic flange will fail, failure is generally pretty random. Whether you have just purchased a new vehicle or have had yours for year we recommend installing this aluminum flange to 100% prevent potential problems in the future.
