Jerry, I don't know about the fan clutches but I am thinking there is some sort of bypass that is defeating your thermostat. I fought the battle of trying to figure out why the fan clutch "thought" it was time to turn on when it shouldn't and have settled on air flow in the engine compartment. Funneling the air through the radiator instead of around it and using a "spoiler" to pull the air out the bottom has fixed that problem in my coach. I use a lighter duty AZ fan clutch and the standard fan and have none of those problems even in Arizona in the Summer - I did before. By the way, make sure that thermostat is a "fail open" type?
