Dodge lovers: I have a 2000 3500/5.9L diesel and 5 speed. I pull a 34' fifth wheel. I'm experiencing the temp gage starting to reach temps it has never reached before. My first suspicion is aweak radator cap even though I'm not throughing antifreeze. My second guess is me. I've backed flushed thesystem and added new fluid. I do hear the clutch fan come on. Before I go to the dealer give me some ideas
