deleted 4500 running hot?
 

So quite often when hauling, my truck runs 210-220degrees and fan clutch kicking off and on a lot. Never had another truck run that warm, or fan clutch kicking on often. Dealer said these 4500/5500 trucks run warmer...but doesn't seem right and I just don't like it running that warm. Also, I had replaced the stock thermostat with a lower one, maybe not low enough. Any thoughts? Thanks!
