Well low and behold I drove the car to my friends shop that's around 50 miles of mainly highway driving, ran into some traffic on this 100 degree day and she overheated again. I have since swapped to a Mark VIII fan instead of the Taurus do to the fan dying on me some months ago. I checked everything out and decided to order a new radiator, my Griffin is 15 yrs old, maybe just not cutting it anymore. I have tried everything but relocating the trans cooler somewhere else.
Lower fan has a sleeve and will not collapse so I know it's not that. I may remove the thermostat 160 degree and run a Moroso washer/reducer instead. On another note, has anyone run header wrap to reduce under hood temps? This car gets hotter than hell under there!
