OE Quality Lower Radiator Hose

Rein CHR0598 is an OE-quality radiator coolant hose for European vehicle cooling systems. It is built as a direct replacement for the original hose assembly, with the same branch sizing and thermoplastic quick-connect fitment details used by the factory design. Compatible with 2013-2017 BMW X3, lower and 2015-2018 BMW X4, lower.

  • Direct replacement for OE radiator hose assemblies
  • Reduces installation time with application-specific fitment
  • No cutting, refitting, or hose adjustment required
  • Helps prevent leaks from reused quick connectors and O-rings
  • EPDM construction resists heat, salt, road debris, oil, and contaminants
  • Black finish with factory-style routing and dimensions

Built for BMW Cooling System Service

This Rein radiator coolant hose is engineered for the lower cooling circuit on BMW X3 and BMW X4 applications. The hose follows OE dimensions, including a 15-inch centerline length and matching end diameters, so it installs as a direct service replacement rather than a universal hose adaptation. For BMW X3 lower hose and BMW X4 lower hose service, CHR0598 supports a clean repair that matches the original configuration.

This part cross-references BMW OE numbers 17127601856 and 17127639213 for the same application.

Common Problems This Hose Helps Address

  • Coolant leaks at aged hose connections
  • Cracked or softened rubber from heat cycling
  • Leak points caused by reused quick-connect fittings
  • Improper fit from trimmed universal hoses
  • Cooling system service delays from mismatched dimensions

Installation Notes

Verify the lower hose routing and connector style before installation. Because this is an application-specific hose, no cutting or refitting is required when used on the listed BMW X3 and BMW X4 applications. Inspect mating surfaces, quick connectors, and O-rings during service to help ensure a proper seal.

Quality Assurance

Rein designs this hose as an OE-quality replacement for European vehicles, matching the original hose shape and connector design. Part number CHR0598 is backed by a 24-month or 24,000-mile warranty.
