i read somewhere that there was a factory bulletin to remove some 7 blade clutch fans.With the
fan clutch slipping at high speeds the big fan was turning slow and actually blocking air flow.
An easy test would be to try a standard 7 blade mechanical fan.I've never had anything but bad luck with clutch fans...they all ran 200 - 205 on the highway and hot at idle as well.
Actually that was my next step! Glad someone else agrees. I have several 7 blade mechanical fans in the attic.
After reading you had a clutch fan, I too was going to suggest a switch to a fixed blade fan, I don't run nothing but on my toys, every clutch fan I've had always resulted in high running temps
The condenser and tranny cooler ain't helping either, but they're necessary evils, if you find they're the cause, depending on their size, perhaps they could be relocated to expose more surface area of the radiator to incoming air, esp were hot water is initially entering the radiator...
