I know there is as thread covering this already but I couldn't find a direct link for one other than people suggesting eBay or lkq. Just curious if anyone with knowledge on the swap if this is the correct part? And if not, can u post the right link. Idc if its AutoZone or Napa or whatever

looks right, basically it's any chevy 145 amp truck alternator from 2000-2005, after 2005 they changed to the different PCM controlled alternator thats a 2 pin plug instead of the 4 pin plug, but watch out and make sure the one you select specifically states it 145 amp.

edit: if you look at the specs on each alt, they need to be the 145 amp and Alternator Diameter of 144mm which half of the ones in that list aren't.

 

So this should be good right?

I got mine from Napa. It was from an 03 Escalade w/ 5.3L. You'll need a larger serpentine belt too.

 

I read that the pulley size was the same and you can use the factory belt

 

Ok well the belt and pulley match up fine... but now here's another issue I might have

I posted in the thread a few times but nobody has been on in a while so I figure I just stay a new thread since in the 6 pages I read through I didn't see anyone even ask this.

Ok so might have ran into a problem.I'm hoping it's something easy to solve though. I have 98 trans am and I'm doing the alternator upgrade. Mine is from an 04 escalade. Anyways I was also replacing the connector with the same part referenced in this thread

Anyways as I was about to splice the wire to connect the new one I noticed a possible problem. My new connector has 4 wires, my stock only has one. Do I only splice the one connector and pull the other 3 or what? I really don't want to reuse the same connector as you can see it's pretty thrashed



Old connector with only one wire going into the connector
