Detailed Description

Rein CHR0635 is a radiator coolant hose designed as an OE-quality replacement for the upper cooling circuit on select BMW diesel models. It is built to match the original hose assembly used on 2014-2018 BMW 328d and BMW 328d xDrive vehicles, making it a practical choice for technicians and DIY repairs that require a precise fit. The hose uses EPDM material for durability in high-temperature engine bay conditions and resistance to salt, road debris, oil, and other contaminants. This part cross-references BMW 17127811127 for the same application.

Because the hose follows the original size and shape, CHR0635 supports a cleaner installation on BMW 328d upper radiator hose service jobs and helps maintain proper coolant routing in the cooling system.

Common Repair Uses

Installation Notes and Tips

Verify the upper hose routing and connector style before installation on 2014-2018 BMW 328d and 328d xDrive models.
