Fan nut size??

What size is the fan nut on a 1997 12V?? Loosen is clockwise as looking at the front of the engine correct?

mine is a 36mm. I believe the 12v is the same. and yes it is clockwise facing the engine. the other way of telling on the fan is, look at it and see what direction it turns. they go the opposite way to come off, for the most part. there are exceptions.:thumbsup

How are you holding the fan hub??

There are special tools that grab the hub bolts to hold it.You may have luck hitting the wrench a sharp wrap.

Park Tools sells a thin 32x36 m/m wrench for bicycle headsets (any bicycle shop) - I use it to loosen the fan nut on my Bimmer (which is 'reverse' threaded) by "tapping" it with a metal (not composite) hammer/sledge to break it loose.

My method; Before removing the belt, clamp a vise-grip on it (not too tight), sticking out towards the drivers side. Get a 2X4 a foot and a half (or so) long, and place the end against the vise-grip. Whack the other end with a hammer. It should break loose easily.

It isn't a 36MM. I am having a terrible time getting it loose. I have a fan removal tool which is holding the fan very nicely, just can't get the nut to break loose. Clockwise looking at the front of the engine to loosen the nut correct??

I just took a punch to the edge of the nut, beat it good once and it was loose, nothing was holding anything back except the regular tension of the belt... I think it is 1 7/16" ... And yes, if you are at the front of the engine looking at it and the wrench is on the right, yes beat it down..or clockwise.. it will come

You could just use an air chisel. If you do it right, it doesn't remove much material at all... Works great too!!!

Thanks for the advice. I finally got it. Had to vice grip the pulley against the cover and swung at the wrench with a 2x4. After about 5 minutes once I got the pulley to stop moving it broke loose. Was tough coming all the way off. Trying to figure out why, I have had it off 2 other times. Wandering if the 4000+ rpm really snugged it on there.
