You have a 7/70 powertrain warranty. Don't see where they would cover an overheating issue under a powertrain warranty, but hey, go for it. Never know unless you try...
Overheating is generally caused by radiator troubles which would NOT be cvered. Now, if the problem is with your t-stat or your waterpump, then YES it would be covered. They WILL charge you even for diagnosis if it's not going to be covered under warranty, so you really gotta figure it out before it goes in.
i dont have a clue what it is!!!! it doesnt fully run hot but when i have a load on it climbs up between half way and the 3/4 mark, and when i driving it empty it does fine till i stop or get in traffic then it wants to climb, but as long as i have clean air it runs pretty normal!!!! i have changed the thermostat because thats what it was acting like was wrong... it a 4.7L with 45000 miles on her!!!
