Anthony has one on his and no issues. if its not kicking on sooner or not working right, just return it and get a new one.
I had 2 bad ones as the one I put on when I did my swap died a similiar death, but it lasted about 50k miles before it completely died. To some thats considered the life of a fan clutch, but to me that was premature failure. That said, I'm still running a Hayden, it's just kennedy's special calibration. If I was to buy another hayden though, it would be one in a hayden box, not a parts store reboxxed one.

Figured I'd link this here..
http://www.duramaxdiesels.com/forum/...ad.php?t=77248
All the temps have dropped some more than others, required throttle has dropped for given load, mpg is up if I can keep my foot out if the turbo,
Video if me getting on the freeway with window open.. LED lights in the rear cause fast blinker

Compliment of Mr wolflly


This is load home from Iowa 17500lb of deer feed 5' tall 8' wide ~34000gross normal I run 60-65 in 5th with similar loads, with clutch fan, with solid hub ran easily 70-72 in 6th.. it would run 70-72 with thermal clutch but it would get warmer than I'd like and mpg would drop

Wow not the results I figured at least for mileage. Surely it can't be the weight difference between the hub and clutch? Any idea what that difference might be?

Only thing I can think of is the increased air flow across the CAC cooling the air off more than normal...
Seams it's currently net positive on HP
The 1° cooler equals 10hp thumb.. seams to come to mind but couldn't get AIT logged
