I would say with 105 deg.F. ambient 90 - 100 deg.C. coolant temperature is normal, depending upon how fast you are driving and the road grade. > Secondly, the temp gauge was flicking around alot. up to 100, > down to 70 or so (never down to the peg though). What the deal with > that? That's due to a bad instrument ground. With the instrument cluster out, in front of where it normally sits and toward the center of the vehicle you will see a bunch of brown wires with ring lugs on their ends and a bolt holding them all to a piece of the metal frame. Cleaning these lugs (and using a contact cleaner) will solve the problem. The bolt holding the lugs is much easier to get to with the dash out, but that's much too much work to do to fix a bouncing temperature gauge. One cheesy way to solve the problem is to run a new wire from the ground on the instrument cluster to the engine block. > Going to clean her up now and give her the good once over. > > think I did okay for $800. Sounds like it. Does the AC work at all?
