Slant 6 Turbo 68Dart Project

Originally I had gone through the process of the entire cooling system over the past 1 and a half years. The radiator is only a year old, a brand new aluminum unit. But I will check the rad for cold spots. It was flowing absolutely fine. Hoping it's not shot already.

Good info on that rod I found. That makes sense. I can flush the rad as well, but thinking I am dancing around an issue that may have been inside the block and has returned. But pumping water into the rad is free for me, but I'll test for cold spots first. I bought one of those infared guns specifically because this car used to overheat...
