I tried to install a new fan clutch, the Hayden 2781, and it doesn’t fit. The heat sink is wider and does not fit inside the fan, Otherwise it would fit.
So, wanting to make some forward progress, I installed a spare used one i found in my parts hoard. I cant recall where it came from. Immediately, I could tell there was a good amount more resistance when cold than the one that was installed. At start up I also could definitely hear more air moving. I couldn’t get too far away as my 12 year old has friends over. So, I drove it at about 20 mph around our very hilly neighborhood and made the 2 mile climb from the entrance off the highway at about 6300 feet to about 8500 feet at our house. There was a 15 degree temperature drop compared to the old fan clutch but I still got up to 220. In my mind, that is too hot and I haven’t put it to the full mountain climb from the desert where the problem was first encountered.
Also, the issue has gotten progressively worse since first encountered.
