Radiator tips for 67 Dart with 440

From my minimal research Cold Case and ECP seem to be the rave lately

Just because they are the latest "hot ticket" doesn't mean they are the correct part for the application.

If the temp goes up to 220 while driving 35 mph there is a problem with water flow, or air flow, etc.

The fan will only be of any use at idle or really slow speeds.
