Hi Chris - Need to know how difficult it is to change out an a/c compressor clutch on a 1997 saturn SC2?  The compressor clutch is making a loud noise when not engaged (a/c off) and seems to quiet some when it is engaged.  It looks as though the screws are not holding the cluth in place and is moving when it should not be?  If that makes sense?  I don't believe the condensor is bad?  Or how can I tell?  I am hoping the condensor is not faulty as they are somewhat priceless in cost?  One can buy the clutch separately but I don't know the procedure to take it off properly?  Do I need special tools for that?  I have done many repairs to my cars over the years but no to the a/c system components?  Anything you recommend will be a great help?  Thanks for taking the time and giving expert advise?

Bob,
 Removing the A/C compressor clutch is not hard.  You will need special tools to get the job done.  For the most part the 97 had only one type of clutch.  However, there are exceptions to every rule.  Thankfully they were all GM style compressors so the tools wont be hard to find.  You will need a compressor clutch kit.  This is a specific set of tools that you can buy/rent/borrow at your local big name parts store.  The procedure is not hard.  It's kind of like removing and replacing a pressed-on power steering pulley.  The only thing that you need to watch out for is the back-spacing of the new clutch.  I don't know the exact tolerances, but, with a gap gauge, measure the distance between the old clutch and the compressor, and then, measure the distance between the old clutch and the old clutch cover. (at the very end of the pulley you will find a gap between the clutch and the clutch housing)  This is the critical gap.  Too tight-compressor runs all the time and clutch burns out.  Too loose-clutch can't contact clutch plate.  The condenser should not be bad.  If it has no holes and the fins are not pressed over to the side I wouldn't worry about it.  If you need a play-by-play for this procedure let me know.  I'm sure I can find it.  Hope this helps.

Thanks a bunch Chris on your expert advise!  If it is not asking too much of you, a play-by-play procedure, pictures, a specific web-site showing this would be so great!  Pictures tell 1000 words!  I wouldn't want to spend the money on the parts and get stuck with a faulty installation on my part that causes more problems?  Your advise has been so helpful!  Bob

Bob,
 Send me your e-mail address in a reply message and I will send you the play-by-play.  Make sure that you do not send your entire e-mail address like you normally would (helping you to avoid spam)  Example:  john at orielly dot com.  It seems silly but it will save you future headaches.
