Review on πŸ”§ Optimized Expansion Tank Cap by URO Parts - 17137516004 by Shawn Xayamonty

Revainrating 1 out of 5

Attention buyers: fits but does not work

Fits but does not work. The 2009 750i has a pressurized expansion tank. The coolant flows out of this cap under negative pressure, ie the coolant leaves the tank through this cap even if there is no overpressure in the system. Disappointing but not worth the effort to return. I bought a cap from BMW for $60 it's crazy but it does the job perfectly. 2009 750i with 96,000 miles.

Pros
  • Easy to read control panel
Cons
  • I will add later
