Product Details

The Keystone BM3014107 is an OEM-replacement coolant reservoir (expansion tank) designed as a direct-fit replacement for BMW 5-Series and 6-Series vehicles (2004–2010 Sedan and Wagon body styles). This unit replaces BMW OEM part number 17137542986 and restores proper cooling system function without modification.

The coolant reservoir serves as the pressurized holding tank for engine coolant, maintaining the correct fluid level and system pressure as temperatures fluctuate during normal engine operation. A failing or cracked expansion tank is a common issue on these BMW platforms and can lead to coolant loss, overheating, and engine damage if not addressed promptly.

Key Features:

  • Direct OEM-style replacement — no cutting, splicing, or modification required
  • Includes cap and coolant level sensor for a complete, ready-to-install assembly
  • Engineered to meet original equipment fitment and function standards
  • Compatible with Sedan and Wagon body styles
  • Replaces BMW OEM part number 17137542986
  • Manufactured by Keystone Automotive Industries, a trusted supplier of collision and OEM-style replacement parts

This complete assembly — reservoir, cap, and integrated sensor — ensures a straightforward installation and reliable long-term performance, making it an ideal solution for professional collision repair shops and independent technicians alike.
