Default Need to bowwow .. Alternator.. I know.. I know

Anyone in SoCal near to San Diego have an old or unused alternator (i'll buy it if cheep).

I've got a squeak that I'm trying to nail down and I've got it narrowed down to the alternator or the power steering pump.

I'm thinking I could swap in any 2004'ish alternator (cuz its easier to pop in and out) run the car and eliminate or identify my alternator is the culprit.

I could buy one.. use it and accomplish the same.. but taking it back they might not like that it was installed....

Not close to SD, but you might check with Scott at The Corvette Shop in Costa Mesa, CA.

When do you get the squeak. What you can try is to remove the belt for the power steering pump, and then turn on the car, rev up the engine and see if you get the squeek still.

I thought about posting something similar, but the PS pump and alternator share a belt. The normal belt routing needs both so you can't segregate them for pinpointing a squeak.

However... it does look like you could get a shorter belt with 2 different routings to omit either the PS pump or alternator:
  • Belt that wraps only around the PS pump, no alternator (green line). Would be a good idea to have a battery charger during this test.
  • Remove the PS pump (or shift pump out of the way), and wrap belt around alternator (orange line)
    • Looks like the correct belt size for this is 6PK1885. From this post.
The string method is great for measuring the new belt lengths.
And of course it would probably be easier/cheaper if you could simply swap in a different alternator as a test...
