Have a 1984 Regal, 231, all stock parts. I recently (within the last month) got it running right for the first time. I have noticed that every so often, the temperature light will fade on, then go back off. It doesn't come on bright, it's like there's a rheostat on it and it goes from off to about halfway bright slowly, then fades back out. It doesn't do this most of the time and it usually only does it for the first couple miles of a drive when it does happen.
Since it's so intermittent, I can't reproduce it in the driveway to look for a problem. The radiator doesn't leak and the water pump is only a couple years old. Ideas?
