I've had this 2003 for just a month, still figuring things out.
With the AC on, running empty on flat ground at 60mph the temp rises to about 210 and the clutch fan engages until the temp drops.
Outside temp is 85f or so.
Is this normal?
I'm thinking the truck is struggling to stay cool with no load and it's not ready to pull a trailer up and down hills.
Or is the hot AC CONDENSOR creating more heat than the airflow can disperse?
Thanks
My '03 Dodge/Cummins has done it since new. I even questioned the Dodge truck dealer. He did a flash and it did help some.
Our clutches are electrical controlled by the computer I think from '03 and up. Temps around here can hit 110-115 degrees and yes the big 9 blade fan sounds like a hoover craft.
See your dealer if a flash is possible.
A flash can only effect fan operation, and not the temps below that.
The cooling system is large enough they the engine should be running just above cracking temp when not loaded, even with the AC on.
