Also what type of fan do you have, clutch or flex-a-lite or?
I had a problem with my Charger overheating. One day I parked it and left it running and when I came back to it it was at 230*!
Turned ou tthe clutch fan was shot so it was spinning but not really moving any air. I grabbed a flex fan (because that was around) and put it on and the car never got over 190*. It was running a shroud though.
