ok so im currently deployed right now so i can go check out the truck. so here it goes. my wife drove the truck to the river this weekend and had it all detailed and pretty and what not and they dude said your coolant is low you need a water pump. my brother looked at it and said there is zero leaking or anything like that.my wife said that it ran fine there and back 275 miles each way. she just had a major service done on the truck all fluids changed TRANS,COOLANT, DIFFS, BRAKES. etc. so there are no symptoms other than the fluid being low and the truck only has 71k babied miles. could it be it needs to be topped off after the coolant drain and fill. or could the pump actually be bad?? also she said no white smoke black or any smoke. again there are zero leaks. im thinking just a top off.. what dou you guys think?
