Me and my dad finally diagnosed the problem(*)
1) The SuperCharger pullley
-Easy to do, but I don't have the pull tool.And I can't find it ANYWHERE! Where is it?
I keep seeing pullers for 97 and on, but will they work for the 93s? Help me please!
Will any three point pulley puller work?

2) The tensioner assembly (not making noise but needs to be replaced none the less) Also replacing the serpentine belt.

I really need all yhe info that I can get for removing the pulley, do I need the tool or is there another way to do it? I really don't want to spend 150 bucks on the sucker if I can at all avoid it.

thanks in advance for the help folks.

on the 92-95 all u need is to take a old belt and wrap it around the sc pulley and hold it
with a pair of channel lock and remove the 3/4 bolt in the front. then take a 3 jaw puller
that u can buy at ur local parts store to remove the pulley. is the sc pulley have a little
play when u rotate it left and right. if so then its more then likely ur sc coupler that
needs replaced. i had a cladder noise coming from mine and i removed the nose cone
and replaced the coupler and that fixed my cladder/ rattle noise. u have two options.
option 1 is remove the supercharger which u have to replace the gasket.
option 2 is remove the power steering bracket which is what i did so i didnt have to change gasket.

I finally found the instructions for the pulley on the tech page. Can anyone direct me to where the step by step instructions are for replacing the coupler? I hope that I don't seem like I'm lazy, but I've been searching everywhere on these boards and I can't seem to find those instructions.

btw thanks 95 riviera.

man i feel like a NOOB right now. I keep researching and I keep realizing that there are things that I initially overlooked. I'm going to replace my coupler, since there are no bearings in the pulley, and there is a little bit of play on it. I still have to replace the tensioner assembly and will probably do that tomorrow before I go to work.
I'm about to order the parts for the */c coupler.

Are there any recommendations about anything else that I should change, while I've got the */c apart? Is it more or less complicated to take the */c out than to pull the power steering bracket? I'm sorry to be asking so many questions, but I really want to do this right the first time.

time wise. u can remove the supercharger quicker.u will have to buy the supercharger gasket. make sure u get the 2 bottles of oil while ur at it. might think about the snout seal at the same time. mine started leaking when i added the new oil.

Two bottles? The M62 only takes one bottle.

Right, M62 which is the charger in question here does take one bottle. I would probably recommed picking up two only for a future oil change.

It is much easier and quicker to remove the SC than the bracket. That bracket is a monster that has a bolt on the back side bottom of the motor etc.

You will need the SC to LIM gasket (Felpro comes with the yellow coolant port o rings, GM does not)
Red gasket maker (very small tube)
TB gasket to clean the TB while it'* off.
TB Cleaner
Possibly injector O rings if they look bad. Felpro packets typically include only 4 rings.

Some time. and you should be all set.
