Thanks, Stoucthon, that was the answer I was looking for. The temp has never gone over 200. I m not really sure even that much because it has an after-market sender which I was told reads too high. Jerry, it has a real fan and an electric one which is controlled by a switch under the dash. It has only overheated once and that was 14 years ago and that was because the radiator was the original one and it was plugged to stop leak and then sat for 2 years while the bodywork was been done.
