Let us know if this works for you. I would be interested to know driving the same route if it runs cooler for you. I replaced my fan clutch last year with the exact fan clutch you have and it didn't help my high temp problem. Since I couldn't hear the fan clutch engaging until 215-220 degrees I figured I might have gotten a defective one and just last week replaced it again. If that doesn't work I'll be thinking that my radiator might be plugged (although my infared heat gun doesn't show that it is) and I will replace the radiator and the water temperature sensor. I have already replaced the thermostat which appears to be opening and closing at the correct temperature. By the way did you find an easy trick to get the upper fan shroud out?
