FORD 460 Overheating Mystery
1997 Fleetwood Southwind 35P ~Ford 460 engine. I noticed the rig running a bit warm when we first got it 5 years ago. It had 23K miles on it then. It seemed each trip it would run a little more on...

Yes, we are grasping at straws now. I spoke to my transmission shop who said that if the tranny was causing this, I'd have other tranny problems. The rig shifts perfectly, no slipping, no noises.
One theory that made sense was that maybe the clutch fan is put on correctly but the BLADES of the fan are put on backwards. This way, the fan would be blowing air AT the back of the radiator instead of sucking air THROUGH the radiator.
We checked, not the case. A piece of tissue paper held in front of the radiator at idle shows suction from the front toward the back.
Ugh, I'm out of ideas on what this could be. I'll ask about the tranny fluid. The fluid that is in there now has only been run about 5K miles since it was replaced.
Starting to think it's time to sell this RV....or drive it until it won't go anymore...or may try installing auxiliary electric fans somehow.
