This didn't apply to the 2019 and up Rangers. This was on other Ford cars, but not the Rangers. Ranger engines had the fix from the beginning.They drilled coolant ports between the cylinders in the block to even out temps. It worked well. All 2019 and some early 2020 models had the early engine. I remember researching and checking my engine date to see what was in my truck.
