No warranty left on my 07. After "running too hot" session number 2, I called my local dealer and asked if they had a fan clutch. Of course, they did not, but when the parts guy came back saying it was $323. FWIW, NAPA sells a replacement for$ 400. I knew the good old days of simple fan clutches were over.

I'm on my own with this one. I'll be looking at the electrical side of the fan speed sensor this weekend (if it warms up enough). But I find it very interesting that I get hot both with or without my plow on. But I only get codes when the plow is on. These 2 codes P0483 and P0528 don't trigger the CEL. So, I'm thinking they probably showed up last winter while plowing too. I didn't have a Gryphon then.

I'm going to try plowing with the tow tune and stock tunes next time it snows. Just to see if the codes return. (all that's needed is a few miles of driving with the plow on to bring them back).

Thanks for your suggestions.
