Engine/Transmission (1994 - 1998) how to replace fan clutch?

[MAllen]

Does anyone here have good info on how to replace a fan clutch. My fan is on constantly, & we have only had 60-70 degree temps. I believe the clutch is shot. Anyone have any other ideas to the problem. My truck is a 98 12 valve. Thanks

The nut is left hand thread. There is a special tool for removing it. Or you can fight it, I used an air hammer.

That's right it's called a fan clutch tool :-laf:-laf:-laf:-laf:-lafOo. Oo. Oo.

Wow, I was amazed when I had the fan blade and clutch off in a matter of a couple minutes. That wasn't bad at all with the advance auto parts fan clutch kit they rent.

I forgot to mention, I put on the hayden brand from o'reilly's fan clutch. It only runs 60 dollars and has a lifetime warranty. Can't beat that.

Don't be too hasty. NAPA has a lifetime warranty too. They seem to fail only when you are at least 1000 miles from home and don't fully engage when it is very hot. I got tired of replacing them in parking lots and bought an OEM from mopar4less. More money, but it works when I need it.

Be careful of the cheap aftermarket units. You may not be happy when towing in hot weather.

I'm reviving an old one here... Anyone know the sizes of the fan clutch wrenches? I see that Genos has the Lisle 41730 fan clutch wrench set but I can't find the exact sizes here. Instead of a set that only does the one model, I was looking at a more generic wrench set so I may be able to use the them on other vehicles. The set I'm looking at includes 54 mm/72mm 68mm/76mm 83mm 40mm and 48mm.

I read 37mm on my vernier caliper. I use a long screwdriver and a big hammer.

Thank you. I guess the set I was looking at is not going to work.
