i bought this truck a month ago. it has no leaks under the vehicle. the only thing is it eats small amounts of coolant. i checked oil and tranny dips and find no traces of foreign material. it gives about a 10 second puff of white smoke on startup. yet i have to top off radiator every 3-4 days with about about 2 cups +/- .

pressure test the system. you may have a leak and not know it. water pumps are famous for leaking and so are lower intake gaskets
