I have a 2004 Ford F250 with a 6.0L diesel. I was driving home from camping when I noticed the check gauge light came on and i looked and the temp gauge was pegged. So I pulled over and shut it off. My wife was behind me and she said there was white smoke coming out. I looke and the overflow tank was empty so I put in a ton of water and then tried to start it and it just clicked. Then I noticed that there was water driping out of the muffler. What do you think could be wrong? I read somewher it might be a ruptured EGR cooler??? Thank you guys for the help!!
