Dodge fan clutch

I am trying to remove the fan from a 1999 Dodge truck 6 cylinder and I am not sure how to get this thing off. It looks as if it simply unscrews by means of what appears to be about a 1 1/4"-1 1/2" hex but I can't get the darn thing loose. I know you Dodge guys will probably get a chuckle out of my problem here but I just have never had the occasion to remove one of these things, how the dickens does it come off? Is it a left hand thread maybe?

I managed to lock the pulley with a pair of large Channel locks but I pulled so hard on that thing it was bending the pulley! I had called the dealer after posting here to be sure of the thread direction before applying that much pressure, then I spotted that tell-tale red stain at the back of the nut. Fortunately both the water pump and the fan clutch was going to be replaced so the torch was an option, if the clutch had of been good it certainly would not have been after I got the danged thing off!

Large nut like 1 1/2"? They are always the opposite of the fan rotation. I don't lock the pulley but use a hammer to give the wrench a good smack and it's loose and they don't need loctite. When I put them back on, I just get the thing started on the treads some and fire it up and it's tight. Some shadetree mechanics should be hung from the tree....

If I knew who that rascal was I would supply a new rope!

One thing for sure when a person uses that high strength Loctite they better be dang sure that the assembly will never need to be removed, it's almost as bad as welding. I think that an assembly has to be heated to 400 deg. (I may be wrong about the temperature) to loosen up that stuff but I am certain I had to heat it a lot hotter than that. The water pump was out but the fan clutch was loose also so in this case the heat didn't hurt anything that didn't need to be replaced anyway, that was just luck however because if the clutch had of been good it certainly wouldn't have been when I got it off!


Thanks for tip on removing/replacing those things I will remember that if I have to remove another one.

My 97 Tahoe is like that too....i just whack the wrech with a hammer to knock it loose. Do it before you take the belt off that helps some. I used a strap wrecnh around the waterpump pulley to hold it the first time I did it.

You probably already know this but I should clarify something...the THREADS are opposite the rotation so if the fan turns clockwise (counterclockwise if you are looking at it front the front), then the nut loosens the same way the fan turns. It shouldn't take much of a hammer whack to get it moving. The nut never loosens since it's always turning in a direction that makes it stay tight.

we have to remove these often to replace water pumps for ppl

check there if you plan on removing very many in the future

its worth it.

it has two round dowels in the end to hold ones with holes in the hub
