Hopefully someone has a idea. I have a 01 excursion with the 7.2 motor I towed a boat over the week to a lake up in the hills got home and this morning noticed radiator fluid everywhere under my excursion only on the truck itself not on the ground. Figured I had a leak. Could not find one so I added fluid it was about a inch below min. mark filled it up and started it. Took it to the car wash and washed the under carriage and drove home looked for a leak again nothing. I let it cool and looked again nothing.
The only thing I can think happened is my turdo over heated towing this boat up the hills and it released pressure. Can this happen? Spoke to a friend and he said his f250 with the same diesel did it once in a while when he towed a boat in the heat.
Any advise would be great before I go spend a fortune at the dealer.

If your 7.3 is like mine, it will puke coolant out if you actually fill the bottle to the hot mark. I always let mine run alittle low. Having said that, since you found coolant under the truck after it was parked, if you cannot localize a loose or ruptured hose, there is a good possibility that your water pump is failing - it will pee out coolant - if it is making noise while running best to have it checked before you go anywhere
