The dealer said they wouldnt fix it? Ok. Dude, they changed your head gaskets, meaning they had to pull off your entire cab to do so. Also Meaning they disconnected ALL of your electrical components and everything else... It was their fault, and you can get them in BIG TROUBLE for not fixing it. I would love to have been there with you on that one... I would be getting a new TBC before my truck even left the shop... So Call Dearborn Ford in michigan. They are over almost Every ford dealership and will kiss your *** over any problem. Tell them what the dealer said and im SURE whoever the mechanic is will get burned.
