  1. It's possible the coolant tank reservoir cap isn't sealing properly and letting water vapor out. I'd refill and change the cap. See how it goes.
  2. TSB 19-2346 2.0L EcoBoost - Coolant In Cylinders, White Exhaust Smoke And/Or Illuminated MIL According to Ford, the TSB pertains to one of the following 2.0L vehicles with base part number 910. - 2015-2018 Edge - 2017-2019 Fusion/MKZ built on or before 8-Apr-2019 - 2017-2019 Escape built on or before 16-May-2019 - 2017-2019 MKC built on or before 18-Apr-2019 Picture of a 2.0L EcoBoost block with the machined cooling channel on the bore bridge. Picture of a "revised" 2.0L EcoBoost block with small cross drilled holes on the bore bridge. Part number (F2GZ-6009-E) dated 15-Sept-2019 from Spain. One would think that Ford had ample time to address this issue after the 2.0L "twin scroll" redesign in 2015. Why it took until mid 2019 is beyond me. My 2019 MKZ May-2019, not included on the TSB, lost about an inch of coolant in the reservoir during it's first year on the road. The Lincoln dealer did a pressure test for me, but claims it held. So where the coolant actually when is anyone's guess. They claimed the orange coolant is known to have excessive evaporation, but the cooling system is closed. Not sure where it evaporated too. My engine sticker says JV 910 AC / VEP 293 19C05. Does anyone on this forum know when the block machining change actually occurred at the Valencia Spain plant? Is there a method to identify which design I actually have without removing a cylinder head? I assume the latest block part number (F2GZ-6009-E) is revision E. So revisions A,B,C & D must have under gone some changes throughout the years. Is this part number cast into the block somewhere?
