Greetings again Moparians!
Now that I've got my shiny new Cold Case radiator, the NEXT item to upgrade is my fan. I bought and ran a Hayden 2707 last spring, but removed it just over a month ago and returned for the time being to my 6 blade straight steel fan to insure that plenty air is being pulled past that radiator.
I've seen some anecdotes on the merits of the 2797 extreme duty clutch, and also some on the more modest and slim 2747 heavy duty model. Given how I had to shim BACK my fan just over 1/4 inch by using some extra nuts to insure it didn't eat the radiator even with the 2707, I have some doubts about installing the 2797. Can I make this work in my engine compartment or should I stick with the 2747? Do any of you owners of 1966 Chryslers in particular have experience with fitting too much fan clutch between the water pump and the radiator?
