Dropped it off yesterday with a nice polite letter on front seat. Got a call today. Cyclinder 3 and 4 is pushing hot air into the resevoir. They are moving to repair head gasket. Didnt see anything on this in reviews before purchasing. But now if anyone else is having overheating issues with the 3.6 this may be your issue as well. Mine fell under the warranty sice it is a year old with 9000 miles on it. I am just glad this may end my nightmare..
