Ben - your record is still intact! I drove it a few miles today and it is still overheating. But it is a lot better - it stayed around 180 for quite a while, then slowly crept up to just shy of 200. I thought it might stay there but it finally went over 200 just as I was getting back home. But no boilover this time. So the next and last item is the radiator just as you figured. Sometime over the winter I will pull off the hood again and yank the radiator. Cheers, Dave
