New to site, new to Mopar overheating issues

If he has a 6 bladed "AC" pump on a car with non AC pullies theres the slow flow problem. Providing that the radiator doesnt have a partial clog, the easiest way to correct that issue is to put the correct 8 blade pump on.

I have seen people put 8 bladed non AC pumps on cars with AC to run the coolant thru faster. But putting an AC pump on a non AC engine works completely opposite.
