Run whatever...
In our experience, for certain Mopar friends we have replaced their electric fans systems back to the OE mevchanical fans..
The major issue is the electric fans draw high very current, which means one has to totally overhaul the entire OE wiring system.

We have found many overheating issues are due to:
1. Plugged radiator
2. Block needs flushing
3. Incorrect timing
4. Incorrect fuel jet/settings

IMHO...
The Mopar OE cooling systems are overengineered, and I like to keep things original whenever possible..

Have a great holiday season..

Just my $0.05...
