yes, i can smell a slight coolant smell in the truck. The truck has not over heated and i cant see it leaking anywhere except where it comes out of the overflow .

If the inside of your coolant overflow tank is black or cloudy chances are your head gaskets are leaking. You can get a tester from snapon that will test your coolant for the presence of cumbstion gases..
