Detailed Description

Rein CHR0610 is a radiator coolant hose engineered as an OE-quality replacement for European vehicles. It is designed to match the original hose assembly used on the upper main radiator circuit, with the same overall size, shape, and connector style called for by the factory application. This makes it a practical choice for BMW cooling system repair when the original hose has aged, cracked, or begun to leak. This part number, CHR0610, is also a direct reference for service ordering and catalog lookup.

The hose uses EPDM construction and thermoplastic quick connect fittings to support a factory-style installation. Rein CHR0610 is listed for 2012-2016 BMW Z4 and 2012-2015 BMW X1, both in the upper main radiator position. If you are replacing a BMW Z4 upper radiator hose or a BMW X1 upper main radiator hose, this part follows the OE layout closely for a cleaner repair. This part cross-references BMW OE number 17127612444 for the same application.

What This Hose Helps Address

• Coolant leaks from a cracked or deteriorated upper radiator hose
• Improper fit from a hose that does not match OE routing

• Extended repair time from trimming or adjusting a universal hose
• Heat and contamination damage in the engine bay

Installation Notes and Tips

Install CHR0610 as a direct replacement for the original upper main radiator hose on the listed BMW applications.

Replacing aged seals and inspecting adjacent cooling components during service helps support a clean repair.
