Fan clutch shot

[Daniel John]

My fan clutch bit the dust today. It has seized up and runs the fan all the time, causing quite a bit of extra noise, and power loss I suppose. I am looking for some advice. Should I replace it with stock? Or switch to electric? Cost is a concern. Any pros and cons you guys have would help me a lot. Thanks

I've always replaced with stock..... I can't see the extra expense of the electric ones. . Just my 2 cents

I've never had the problem of them locking up, it seems to go the other way for me- never kick in. Anyway, My mom and I both have over 200K on our originals, and no problems so far, except on mine, it was a REAL tight fit when I had to redo the front main seal. I'd go with stock, unless there isnt to much difference between the cost of the two.

from reading on here it looks like staying stock is better, you would have to have a pretty powerfull electric to equal the cooling power of the engine driven fan, I also remember some people having trouble with aftermarket clutches, they ended up going to the dealer, more expensive but they worked... you might try doing a search...

DJ, I replaced mine with a mopar oem fan clutch recently. I remember everyone saying not to buy an aftermarket or parts store clutch because of problems with them. Ordered from dodgeparts.com at about $118 I think. Works fine. Bill

Electric clutch

you got $800-$1000??

Not cheap. Worth a few horsepower cruising unloaded.

Get the Dodge part.

Another day another thing goes wrong! The fan clutch on mine is locked up so its always engaged and howls. I can feel the drag on the engiene, it just doesn't seem to rev as freely.



Mine's a 1990 non-intercooled and there are NO more in the Dodge computer system. Anywhere. The last one in the computer was in Parkersville, Ca. I called & its gone.



Any suggestions on what I can do? I see comments here that say aftermarket is no good?



What about a Cummins fan setup ?



Thanks,

Get your engine number and call Cummins. They cant get you an oil filter without an engine number.

Cummins will probly say its a dealer item, the engines leave the Cummins plant with no fan or fan clutch. Is the intercooled fan different than the non-ic fan? Bill

I've posted this before... . one of the guys here at work put an electric set-up in his 96... . real happy with it so far.

It's a junk yard unit from an older GM (buick I think). A dual set-up.

He has it set up manual right now... gives him plenty of cooling power... but he doesn't tow or work the truck hard other than playing.

I read about the electric fans but I'd like to stay with the engine fan (I think). As I read it, the aftermarket (i. e. Advance, O'Reilly's) fans work, but not as effectively as the factory fan when towing?



So, if I don't tow heavy loads, I don't "need" the factory fan clutch?



The Cummins manual has informaiton about a fan, but I don't think they'll bring up part numbers with my CPL because it didn't come with a fan.



Thanks,

Can someone clue me in on what is wrong with the fan clutches available from O'Reilly's (Hayden brand) ?



Thanks,

 

[Grey Wolf]

btoscano,



I believe that Hayden is the company that made the OEM clutch, If they are not they sure look the same

I'm going to attempt to use a 3300CFM Zirgo electric fan(biggest one I could find) in the conversion project in my sig. This will be with a custom-made PRC aluminum radiator and a Ford Flowerjoke intercooler. I have no idea whether or not this will all work, but I DO know that there is no room for the OEM clutch fan to successfully fit in the front of this project. Besides, the orignal fan/fan clutch ass'y got all bent up when the donor truck was wrecked.



I'll let you guys know how well it all works/doesn't work once I get it all put together and running. Seems as though no one on these boards can give a straight answer to the "will an electric fan work" question.

Works on a 96, I can say that for sure... I work with the guy.

Why wouldn't an electric work? Or even a pair. My friends and I use them on big blocks out four wheelin and keep em cool. In the mud, working the crap out of them, but never over 20 mph. (can't sustain speed in the woods!) It sure would free up a bunch of power. I have 2 junkyard fans on my 440 with stock big block radiator. They are wired into a flexolite automatic switch that senses coolant temp. Have had no leaks. The switch is even adjustable. Want the fans to come on sooner or later all is good. I don't have mine wired up to a manual switch yet, just the auto switch. It works at 90* in hot humid summers here in iowa.



My fan clutch has yet to fail on my diesels to worry about replacing them. On the 90 it will probably get one, as an electric will move much more air when the truck is sitting still idling, or slowly moving(ie city driving, offroading, farm work. )

I called Dodgeparts.com, they told me 52006096 which is what I put on my 89 is just about gone as previously stated, said there was one left at a dealer in California 800-784-9512, but this is probly the dealer so and so just called and said it was gone. . ? Now 52028760 is still available with 24 in a Portland warehouse which he can get. . Is this the INTERCOOLED fan clutch? Are the two fan clutches different intercooled vs non-ic?????

I've talked to the dealer in Porterville, California. They don't have one. There are NO more in the computer system. I talked to another guy at dodgeparts.com & he suggested the intercooled may be different because of the clearance between the fan & the radiator, but he couldn't be sure. He was sure that the difference in clearence between the fan & radiator was important in creating proper airflow.

I was just looking at the differences between the stock thermostatic fan clutches that come on the non inter-cooled and inter-cooled engines. According to the Hayden catalog there are no differences for the dimensions listed. The rub is the depth dimension isn't listed. If someone was to go to a parts store and compare the two, with an eye to the overall depth and distance between the fan mount surface and the mounting nut, you might get lucky and be able to interchange the two. If this is true, then it is great news, cause Hayden shows the inter-cooled model starts in 90 and is the same all the way up to the 99 24 valve. Might be worth a little leg work for you guys with the older trucks. Also if the Hayden inter-cooled will fit the older trucks, then there is a chance the Dodge stock piece will too.
