    THANKS- no I still needed it
    Our trip to Flagstaff- from New Orleans suburb-
    we leave Aug 3-so I have been dragging my feet on preparing the Suburban-
    Hmmm how do I find which alternator-
    just looked at it-I see 130 cast into it?
    I'll check the glove box codes-see what it says?
    Thanks

    Should say right on the alternator (manufacturer label). It's usually 100A, 105A, or 140A. 90% chance you have the 105A but I'd double check.

    Edit: by the way, the 100 or the 105 are considered the standard alternators and the 140 was the optional heavy duty one. The serpentine belts listed above should fit both the 100 or 105 so whichever you have you should be good. Also, duralast belts from autozone are cheaper than AC Delco and are very good. I put one on mine quite a few years ago and it's just now starting to show wear. Just my $.02 Greg

    Greg-thanks
    My belt looks ok-forget exactly when I put it on-
    I'm going to get belt to carry "Just in case"

    I checked my glove box code
    as you guessed- 105 amp code is K68
    ONCE AGAIN as you said 140 amp-option code 8A5
    and you are right 105 belt is 6K960
    ACDELCO is $29 ebay- cheapo brands are $13-guessing AZ duralast probably $15-$20-probably go with AZ as you suggest
    Thanks!!

    PS Couldn't find the label- on the alternator?

    Glad you got it worked out. My alternator has a label right on it that says 105A. Right on the topside hard to miss. I'm guessing yours fell off as it's just a cheap paper label. Common sense would dictate that somewhere on the alternator it's got to say the size... Greg
