I suppose there are some magicians who've done this w/o pulling the fan.

I'm not one of them.

Pull the fan.

You'll need an 8mm allen head to remove the bolt securing the fan clutch; you'll also need to suppress movement of the upper pulley in order to loosen the 8mm allen head. A 19mm bolt that secures the belt tensioning @ the tensioner must be loosened and a 13mm nut up above the tnesioner must be loosened to provide belt slack.

There's a special tool from Stahlwille(8mm) and a special ft. long rod to lock the pulley. Others have done it with stuff laying around the garage.

I believe you'll also need a good 5mm allen head for the dist. cap screws and a REAL good 3mm allen head for the rotor screws. I would spray a little PB Blaster or equivalent on the rotor screws B4 removing. Let it soak awhile. You really don't want these to break off and as small as they are, it could happen.
