This week I replaced the original metal fan with the 11 blade nylon one and the fan clutch with the Hayden 2905. What a big difference in reduced sound and no decrease in cooling The lower temperature of the Hayden clutch is exactly the opening temperature of our thermostats assuming a good thermostat. Reported benefits are better AC preformace in slow traffic and better all around cooling
The 11 blade fan is Mopar #52079654AD and the price at the local dealer was $77.50 and yes it's cheaper on line but when shipping is added it's closer and I've had a bad experience with mopartsamerica and do not wish to repeat it
On the advice from Doug in Colorado I made my own tool to remove the fan clutch. It was easy and cheap. I brazed the 1/4" tips on but bolts and nuts worked for Doug. I also own a large adjustable wrench that has helped me many times over the years and worked fine. Let's see now, 10 minutes to make the tool and ten more to use it
The long arm on the tool rests where the air cleaner box normally sits and the prongs fit into two holes that are in the pulley behind the clutch. The tool is made from 1/8" by 3/4" wide steel. Yes it's flimsey but I had it on hand and it worked well
My 16" Craftsman adjustable wrench fit the fan hub. I tried using the wrench alone and banging it with a small sledge hammer and it didn't budge.
Time to make the tool, remove the old and install the new was 2.5 hours but I did computer field service before retiring and have learned to work faster then most.
Others have found out the radiator is very thin and can be distroyed very easy and recommend putting cardboard between the radiator and fan. It was not too easy to get the cardboard there with the shroud on but once the shroud was off it was very easy to put two pieces of thick cardboard side by side (that's important for removing them) over the radiator's finned area. Then when finished the TWO pieces can be removed from UNDER the car. Easy to see.
Yes the fan clutch is right hand thread. Looking at the metal fan it's easy to see that much of the blades shape was dictated by fastening the blades to the center part, hence the noise 3
I don't need to say anything about Samco hoses other then I got the shiny black ones. They look nice without the "bling" of a bright color. On removal I found the original turbo to cooler was leaking and starting to rip. They had 52k miles on them.
