Alternator Specs?

blueyedevil911 · February 19, 2008

Hello all. This is probably an easy one so I am embarrased but I can't seem to find the amp rating on my 2003. I need to replace my belts and I see that there are either ones for a 105 amp or a 145 amp alternator. I checked on the alternator but see no specs and also went over my original paper work and it does not list it anywhere. Is there a trick to find the rating i have. It is a 2003 1500 5.3 Z71 Ext cab. Thanks

There should be a GM part number stamped on the alternator body. Post that number and one of the parts guys will be glad to tell you what the rating is.

I will try and get that tomorrow. Thanks

You can also use the RPO code to determine what it was built with.

Ok I checked today and I still see no codes on the alternator. Just Delphi Systems. I took pictures of the RPO codes. Is there a website where I would translate the code? I will try a google search in the meantime. Thanks for the help

There is a link to the RPO lookup under "Navigation" in the top left of this page.

I found it! I downloaded a RPO decoder from thirdgen.org I have a 105 amp code K68. Thanks a lot to you all for the help. I am going to save a listing of these options. Now I need to post my next problem!
