Typically if you have continual coolant loss with excessive "burping" you can have head gasket troubles. If the truck is run hard with mods, especially towing up hills, then the residue with little coolant loss maybe the result of EGR heat boiling coolant in EGR cooler. Higher HP from modes causes higher exhaust temps and the exhaust passing through EGR cooler on its way to EGR valve can boil coolant and lead to pressurization that causes cap pressure relief to open and vent some coolant.
The first step is to run lower coolant level. MIN mark on hot engine is good. The exp tank is higher than everything else so lowering coolant there doesn't make it "low" anywhere but in that tank.
yeha i dont have alot of coolant loss this is the first time i have noticed it i drove real hard earlier and it stayed the same but its not like i have to fill my coolant up everyday i have never had to fill it up its still at a safe level
Sounds like no worries then. They have a tsb or service message about running lower level to prevent the staining. both of mine had the dribbles if I kept them at MAX when hot but nothing since letting some out and keeping them down nearer to MIN when hot
