OK, my truck seems to be on it's last legs. First, no AC in the Dallas area! I've dealt with that for years, but now have new issue. Had a intermittant heating issue that was initially diagnosed as a faulty thermostat. Since the radiator also needed replacing, had both things done. Truck continued to have intermittant heating issues, so I took it back. Now, the shop is saying that I have a blown head gasket. Mind you, the day I drove it in, the engine sounded fine -- went to pick it up, and the engine sounded horrible. Am afraid to drive it, now.
So my questions are: 1) Could the repairs have been done incorrectly and caused the blown gasket? 2) What is an approximate cost for replacing a head gasket? 3) Is it worth replacing the head gasket? I own the truck, such as it is, free and clear.
