Key Features

• Direct OE-style replacement for the original coolant hose assembly
• Application-specific fitment for BMW water pump to pipe routing
• Reduces installation time by eliminating hose cutting and refitting
• Helps prevent leaks caused by reusing old quick connectors and O-rings
• EPDM hose construction resists heat, salt, road debris, oil, and contaminants
• Black single-hose design for a factory-style appearance

Detailed Description

Rein CHE0682 is engineered to match the original hose layout used on 2011-2014 BMW X6 and 2011-2013 BMW X5 models at the water pump to pipe position. The hose is built to OE dimensions, including the branch geometry and quick-connect interface, so it installs as a direct replacement rather than a universal hose that requires adaptation. This makes CHE0682 a strong fit for BMW cooling system repairs where accuracy and sealing are critical.

This part cross-references BMW 11537584630 for the same application.

Common Problems This Hose Can Address

• Coolant leaks at the hose connection
• Cracked or hardened hose material from heat cycling
• Damaged quick-connect fittings or worn O-rings
• Cooling system service delays caused by hose modification
• Contamination-related hose deterioration from oil, salt, or road debris

Installation Notes and Tips

Before installation, inspect the mating pipe, quick connector, and sealing surfaces for wear or contamination. Replace damaged O-rings and avoid reusing old connectors when the original sealing components show signs of age. Confirm the hose routing matches the BMW X5 or BMW X6 application and verify the water pump to pipe position before final assembly.
