OE-Style Upper Radiator Hose for BMW

Rein CHR0044R is an OE quality radiator coolant hose built for European cooling systems that require a direct-fit replacement. It is designed for the upper hose position on select BMW 525i and 525iT applications, with the branch shape and quick-connect details matched to the original layout.

  • Direct replacement for OE radiator hose assemblies
  • Reduces installation time with application-specific fitment
  • No cutting, refitting, or adjusting the hose
  • Helps prevent leaks and repeat repairs from reused quick connectors and O-rings
  • EPDM construction resists heat, salt, road debris, oil, and other contaminants
  • Built to SAE J20 R4 D1 standards
  • Black hose with a 10-inch centerline length

Fitment Details

Compatible with 1991-1995 BMW 525i, upper, and 1993 BMW 525iT, upper. If you are searching for a BMW 525i upper radiator hose or a BMW 525iT upper coolant hose, Rein CHR0044R is built to match the OE configuration.

This part cross-references BMW 11531720678 for the same application. The Rein CHR0044R radiator hose is also a direct-fit option for drivers replacing a worn upper hose on BMW 525i cooling systems.

What It Helps Address

  • Coolant seepage at the upper hose connection
  • Cracked, swollen, or heat-aged radiator hose material
  • Leaks caused by reusing old quick connectors or sealing rings
  • Fitment issues from trimming or adapting a universal hose
  • Cooling system service on BMW 525i and 525iT models

Installation Notes

Verify hose routing, end diameters, and connector style before installation. This hose is application-specific and designed as a direct OE-style replacement, so no cutting or reshaping should be required when installed on the listed BMW applications. Inspect mating surfaces and cooling system components for wear before reassembly.
