Andrew, it is possible that the radiator fans are not coming on with the a/c compressor like they should. If this is the case then I suggest that you don't continue to run the a/c because it may cause too much pressure to build up in the system and cause a hose to blow or damage the compressor. Early cars do not have a pop-off valve protecting the a/c system like mid and later cars do. There are plenty of places for intermittent open-circuits for the radiator fans. All it takes is a loose connector, dirty relay contact, etc to cause a problem. Next time the gauge shows hot, just hop out and check if both fans are running. I had one of mine intermittently quit working. It would occasionally run too hot (when the passenger side fan wasn't running). Most of the time the car would stay cool enough. I ended up making several laps up & down interstate just to find the problem. One trip the car would run hot and on another trip the car would run cool. This was my "controlled environment" test. On one of my many trips, the car got hot, I pulled over on the side of interstate and finally noticed that a fan wasn't coming on. Do check all your ground points. There are several. Walt Yahoo!
