Running hot

Man this is a great thread. I'm having the EXACT same issue with my Dart. It starts and heats up normal, will start to raise in traffic, then cool down once moving but at a certain point (220-230) for any length of time it cant recover. I've tried everything too and no help except the clutch fan. I as well have a POS parts store 22" replacement radiator and I'm wondering if getting a recore 3-row job to it is the ticket. I know I can get it done for about $240 but I was trying everything else before going that route.

Tom-Glad you got it figured out and thanks for the info.
