My original alternator gave out at 40K miles and was replaced by a GM
dealer under warranty.
It lasted until 120K miles at which point I bought an AutoZone rebuild
with lifetime warranty
It lasted until 133K miles and the current one expired after 150 miles
What is the difference between them ?
I had to swap pullies on the one I had and the one they gave me which is
a L-98 alternator.
