Well, I dropped my truck off at the dealership and they called me this morning and confirmed my worst fear. They also said it would cost about $6800 to fix! I could have crapped a solid gold brick. Actually, that would have been nice so I could pay for it. Anyway, he said 32 hrs to fix plus thermostats, antifreeze, and whatever else he could think of. I told him I'd get back to him. I immediately called GM customer service and left a message with a lady that helped me before and then I called my usual mecanic for advice. My truck has 76k miles so I felt I had a valid argument for GM consideration. My mechanic called the dealership after he talked to me and then the dealership called me and said that they would do it for 3k now. I guess he told them that I had already made a call to GM. Well, my GM lady called me this evening, but I was at a restoraunt and didn't answer. She said she wanted me to call her tomorrow and discuss it. Maybe I'll get it all done for less. I need all the help I can get since I'm getting married in June and we're paying for our own wedding. My fiance was ready to divorce me before we even got married. I'll keep you all posted.
