The radiator is a three row champion radiator. The coolant system cap pressure is a fliptop type 16 pounds. I have tried lower pounds nothing has changed. Obviously it would run hotter at a lower pound. I have never let the car get over 220. I’ve shut it down every time. The engine does not even have 150 miles on it. no matter if I’m on the highway or running around town temperature just continues to climb until I have to shut it down. I have tried different CFM coolant fans, etc. nothing seems to work. I can spend the engine over with a half inch drive ratchet without really any problems. And the spark plugs are in. Any help is appreciated and I thank you.
