Yeah I'm curious if newer rigs have a different FIPG and so aren't subject to this issue, or if it's just age related. I've got 149k miles on the truck now.I am curious to see what is the newest 200 to see this coolant Valley leak/repair. I don't recall seeing on here any of the 2016 + posting about this. A lot of 2013 and older like our model years.
