What This Hose Helps Address

  • Coolant seepage at the expansion tank connection
  • Cracked or hardened hose material from age and heat cycling
  • Restricted coolant transfer in the ventilation line
  • Incorrect hose routing during cooling system repair
  • OE-number mismatch when sourcing a BMW engine coolant hose

Installation Notes and Tips

Verify the OE number 17 12 7 584 405 before installation and compare the hose length, width, and routing to the removed part. Inspect adjoining fittings, clamps, and plastic necks for wear before reassembly, and confirm the hose is seated correctly at both connection points on the BMW cooling system.
