  • 17111742231 is an expansion tank cap from Mahle Behr for BMW.
  • The coolant expansion tank cap allows access to the cooling system on your BMW so it can be filled through the expansion tank. Additionally, it completely seals the cooling system allowing the cooling system to pressurize and raising the boiling temperature of the coolant being circulated.
  • If you see a white crusty film around the expansion tank cap on your BMW, the cap is not sealing properly creating a pressure leak that will result in your BMW’s cooling system to lose coolant and to eventually overheat.
  • This Mahle Behr engine coolant recovery/expansion tank cap is 2.0 BAR cap manufactured to the exact specifications for most BMW models from 1991 through 2006.
