Product Details

The Rein 17-12-7-521-777 is an OE-quality upper radiator hose designed to connect the radiator to the thermostat housing on BMW vehicles. This precision-molded hose is manufactured to exact factory specifications, ensuring proper fitment and reliable performance.

Key Features:

  • Constructed from reinforced rubber with fabric lining for durability
  • Includes quick-connect couplers for easier installation
  • Features aluminum mounting flange to prevent common failure points
  • Molded hose design matches OEM specifications exactly
  • Direct replacement for BMW part number 17127521777

Over time, exposure to extreme coolant temperatures causes rubber hoses to deteriorate through cracking, swelling, and splitting at clamp points. Replacing worn coolant hoses at the first sign of wear prevents catastrophic coolant leaks and potential engine overheating. This Rein Automotive replacement hose delivers the same quality used in original BMW production, providing long-lasting durability and peace of mind.

OEM Cross-Reference: BMW 17127521777, Rein CHR0535
