I've read most of the posts on the forum about the pros and cons of replacing the clutch fan with an electric fan, but am still interested in doing this. I saw a 4x4 extreme last week where they attempting to take a 8mpg dodge v8 to 20mpg (and yes they will use this truck for towing). The very first thing they did was replace the clutch fan.

 

I couldn't find anything on the forum on exactly how to remove the clutch fan. Naturally, you have the big shaft from the WP to the fan, you have the 12mm that appear to only hold the fan blades in place on the clutch and you have the 10mm that appear to only hold the belt spooler (or whatever you call it) in place.

 

So, what are the steps to remove this?

 

Thanks in advance!

I just swapped out my water pump on my '96 this afternoon, of course first you'll need to remove the fan shroud, then with the belt still on, take a wrench, or a large crescent if you don't have metric wrenches that large, and place it on the shaft connecting the clutch and wp, and tap the wrench and it should come off fairly easy, the threads are regular not reverse incase you didn't know.

 

Let me know if you have any other questions

Thanks for the help. I couldn't keep the pulley from turning, so I decided to try the "wire hanger" recommendation in another post. This actually worked very well. Slipped a hanger through one of the small holes, tied it the alternator bracket and it held.

I replaced my clutch fan WAY back on a diesel-with BIG ele fan[$169.] i never recouped my cost in any gasmileage advantage---i used to be on the Cummins diesel/Dodge newsletter[internet was not up and running much in 1986]. A lot of the guys traded the stock one for a Hayden, or Electric fan... but more for reliability than any gas savings.... biggest help is custom tune[like Black Bear] and tri-wye headers/custom exhaust in my book

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
