briandors Posted July 31, 2006 Report Share Posted July 31, 2006 My 1995 3100 Cutlass Supreme convertible needs a new starter. (Yes I'm sure it's the starter.) I've done searches and read up. It sounds like a lot of work on a 3.4, but I found less detail of the job on a 3100. After I disconnect the battery.... Can I just unbolt it and wiggle it out? Do I need to remove AC lines, or the flywheel cover, or anything? Also - people talk about buying a newer lighter, smaller, gear reduction starter from a newer 3100. Do I just go to the store and ask for a 2005 Buick Century 3100 starter and that will work perfectly?? Thanks. Brian Quote Link to comment Share on other sites More sharing options...
briandors Posted July 31, 2006 Author Report Share Posted July 31, 2006 I just compared pricing. The newer 3100 starters (Malibu/Century 02-04 timeframe) are like $60 more than the old ones. I think I'll stick to a 1995 design. Quote Link to comment Share on other sites More sharing options...
slick Posted July 31, 2006 Report Share Posted July 31, 2006 Yeah, unhook the neg. cable, unhook the little cables on the starter, remove any little plastic guards that would prevent the starter from coming out(you will be able to see them), unbolt the starter(2 bolts), and pull it out. Now, if you have an oil cooler, you may have some lines in the way. But, if your cool like patgizz(did this on a 3.4), use your muscles and bend them outta the way(not too much to break them though), then you should be able to slid the starter right out. Yes, the newer starters are smaller and more lightweight. Bolt right up with no issues. Quote Link to comment Share on other sites More sharing options...
briandors Posted July 31, 2006 Author Report Share Posted July 31, 2006 The engine is stock. Can anyone tell me if a stock 1995 3100 Cutlass Supreme has an oil cooler?? Quote Link to comment Share on other sites More sharing options...
slick Posted July 31, 2006 Report Share Posted July 31, 2006 Most likely no. You mainly seen them on the 3.4's. Quote Link to comment Share on other sites More sharing options...
briandors Posted August 1, 2006 Author Report Share Posted August 1, 2006 Got the starter replaced this morning. Was pretty easy. I'll write a how-to soon. But my question for now is: no shims came in the box, although the AutoZone computer said it would need shims. The old and new starter looked the same, so I just installed it as is. It starts well, no grind. But right after starting I hear a high-pitched whine for a second at most. Is this going to cause trouble down the road?

slick Posted August 1, 2006 Report Share Posted August 1, 2006 Well, I knew I needed a shim when it would start, right before it stopped cranking there would be a small screech or squeal. Very short, but loud. So, sounds like you may need one. Nothing more than .010" I would assume. Quote Link to comment Share on other sites More sharing options...
terryk2003 Posted August 1, 2006 Report Share Posted August 1, 2006 were there any shims on your old starter?...if not, i'd say u probably don't need one...thats just the sound of a healthy new starter... Quote Link to comment Share on other sites More sharing options...
briandors Posted August 1, 2006 Author Report Share Posted August 1, 2006 No there weren't any shims on the old one. That's why I'm not sure if this is "electric motor whine" or "gear whine". I can definitely say the old starter didn't make this noise. What if this is gear whine? Am I likely to damage the new starter (not so bad, has a limited lifetime warranty and the guy told me i don't need a shim). Or will I damage the flywheel, that's not good at all.

briandors Posted August 3, 2006 Author Report Share Posted August 3, 2006 I tried adding some shims. First I put a 1/32" on, didn't seem to make a difference. So I took it out and put a 1/16" of an inch in there (0.0625"). Still doesn't really seem to make a difference. Makes me think what I am hearing is the motor assembly itself and not gear whine. After all, shouldn't the sound have gotten either quieter in volume, orn shorter in duration, after I shimmed? Assuming it still needs a thicker set of shims??

briandors Posted August 3, 2006 Author Report Share Posted August 3, 2006 I know, I think you were right Terry! Sorry. I got opinions from several places and most people said I needed to shim or I'd reck the flywheel so that's why I went ahead and tried that. Now I have to decide whether leaving the shim in there would cause any damage? I wouldn't think so, no grind. I think I'll leave it be.
