cdictas Posted February 7, 2006 Report Share Posted February 7, 2006 Need some input from the team, This past Saturday was such a nice day, I decided to investigate what was involved in replacing my alternator (noisy bearing) in my 99 STS. Having read the manual, which says to remove the fan and lower the alternator out the bottom (clearly not enough room on a 99) and all the historical postings, I can tell its going to be a _itch of a job. So I've decided to tackle this job in the spring. One of the posting indicated that the best way to tackle this job is to remove the radiator and fan in order to gain access to the alternator. Another post indicated that by removing the AC compressor (requires evacuation of the AC system) you can lower the alternator down and out through the passenger side wheel well access panel. What about lowering the engine about a foot (a nightmare thought, I Know) in order to gain better access, does this make sense? Has anyone recently replaced their alternator in a 99?

cdictas Posted February 7, 2006 Author Report Share Posted February 7, 2006 Johnnydone, Starting in 1998 the Seville's were redesigned. Access to the alternator from under the car seems worse than on earlier models. Link to comment Share on other sites More sharing options...
JimD Posted February 7, 2006 Report Share Posted February 7, 2006 The '98 Service Manual has 10 step program for generator removal (page 6-335+). 1. Remove the negative battery cable. 2. Remove the accessory drive belt. (Okay, some of these are obvious). 3. Remove the radiator. 4. Remove the air conditioning condenser. 5. Raise and suitably support the vehicle. 6. Disconnect the coolant outlet hose from the generator. 7. Disconnect the coolant inlet hose from the generator. 8. More obvious stuff. 9. More obvious stuff. 10. Yet more.... There could be an easier-simpler-quicker method, but the dealer's shop will charge the time to do the above. How long can you listen to that bearing? Jim Drive your car. Use your cell phone.

cdictas Posted February 8, 2006 Author Report Share Posted February 8, 2006 JimD, Thanks for the info. I've been living with the noisy bearing for 10K miles now. I did find that section in my 99 manual. It looks like there's no easier way to do this. Link to comment Share on other sites More sharing options...
