ken's caddy Posted March 17, 2004 Report Share Posted March 17, 2004 Is there any tricks on removing and replacing an alternator on a 1997 STS? Mine is making noises. I heard that the best way to get it out of the car is from the bottom. What other information will I need to get the job done? Should I get a new or rebuilt one? Cost? Thanks Ken Link to comment Share on other sites More sharing options...
Bentham Posted March 17, 2004 Report Share Posted March 17, 2004 Not sure on an STS, but my 93 sls was fairly easy.. just MAKE SURE you get an AC DELCO. Are you getting the 'battery no charge' on your DIC? -Eric Eric 93 Cad Seville 100K 95 Chev Blazer 143K [garaged summers] Link to comment Share on other sites More sharing options...

Thanks Ken Can't help you with the remove and replace. But would recommend a GM rebuild (see www.gmpartsdirect.com part # 10463385 for $125 plus 20% S&H). Aftermarket rebuilds are generic and do not marry well with a pulse width field current system. Or, the bearings and other pieces are available if you feel like rebuilding your present alternator (not a tough job). Jim Drive your car. Use your cell phone. CHOOSE ONE !

druhl Posted March 17, 2004 Report Share Posted March 17, 2004 you're in luck, I just changed my 97 sts alternator the other day for the exact same reason. The alternator cost $125 and it was alittle trouble to get it out. You have to change it from the bottom, it is the only way. I had to take out the pass. side radiator fan also. Not much room between the rad. and alternator bracket but it will come out. Be careful for the radiator, I marked mine up a bit. I'm not sure if you ever changed an alternator before so I am going to say first thing DISCONNECT THE BATTERY. You have either a first production or second production alternator if you do not have a heated windshield if it is like mine. I still am not sure what the difference is but mine was a second production for what that is worth. Good luck and if you have any other quesitons just post. druhl Link to comment Share on other sites More sharing options...
