I'm sure the t-stat is working as it gets up to normal temp pretty quickly where it didn't before when it had no t'stat. Thank you for the advice on running a t-stat vs a washer. It normally runs 180 down the highway but when I stop at multiple stoplights it will get up to 200 and then I shut it down. It only takes about 10 minutes to cool down and it has never boiled over. It did quit running once which I attributed to vapor lock. I have since insulated the fuel line to the carb and haven't had that situation again. There is air going through the radiator from the fans so I assume they are pushers. It did run cooler when the temp was lower. I guess I will just leave it in the garage when it's over 80, LOL. Just kidding, I drive this car a lot and love to be in cruises and would really like to solve this situation. I have been advised to modify the hood latch and make more room, put a fan behind the radiator and try that. I have also been told the heat gauge may not be accurate??
