I assume I have >to remove >the hex nut/bolt in the middle...any idea what size that is? 36mm. This is a good excuse to get a 1/2" socket wrench with a 16" (?, it's long) handle and adjustable head ;) You will need an extension since it's kinda deep in there. >Once I have >that out, do I use a puller, or is the fan threaded on there? >If not, do I >even need a puller? Hmm, one of my shop manuals said it could be pulled straight off but didn't specifically mention a puller. I believe the Bentley said to use a puller. If it doesn't come right off then use a puller (you'll probably need one). Is this an ambiguous enough answer for you?? >Is there anything after the fan removal >that will be >tricky that you can shed some light on while we're on the subject? You will need a torque wrench for tightening the bolt properly. Also, there is a paper shim (gasket) that fits between the pulley fan and its seat. I don't know about the early models, but mine had a dowel in the mating surface so the fan could be placed exactly back. Mark your pulley fan against the crank with a grease pencil (China marker) just in case. This is especially important if you had your engine balanced! I know for me that getting the bolt out with the engine in the car is difficult since my bolt is Loc-Tite'd in there at 125-ft/lbs (NOT recommended for a stock engine!). I made a pulley lock and you can see it on my Type Three Tech page (http://www.geocities.com/MotorCity/Speedway/1641/ ,about mid-page). If you can make something like it, it will definitely help. You DON'T want to use a pipe or wrench or screwdriver wedged in there to hold you pulley fan since you have a very good opportunity for chipping the fan blades. Trust me.
