Coolant is dissappearing FAST!!! pulled fifth wheel a few weeks ago and hadnt checked anything bc temps have been fine. Got my mini maxx in last night ran dpf on hot tune for about 2 hours not really pushin it hard. Temps were around 190(coolant). Took truck today oil changed at dealership and they discovered i had low coolant. Drove about 30 miles home and back to low coolant after they topped it off. Mind you i took the mini maxx off last night and loaded stock tune back on truck. Appears to be leakin from around egr. How do i stop this?
