Hi folks, I've been having some issues with the truck getting hot, but only in stop and go traffic on very hot (90+ degrees) days.. My theory was to go after the fan clutch first. I'm glad I did. Here is a picture of the old and new fan clutch side-by-side. You'll notice on the old one that the coil that controls engaging is completely missing..... I've put the new one on, and hoping this was my problem...

 

Hope that works out for you. Nice find.
