This is a generator. Good enough.

As advertised. Better quality than the 3rd party alternator that was replaced. Didn't solve the periodic voltage drop problem, but it turned out to be an extra air pump or something else.

Pros
  • Handsfree
Cons
  • Nothing

This was a fantastic alternator OEM

Replaced them when replacing the AC system on the Trailblazer. It is not easy to get out of this model, but it is worth replacing after this work. This is a much better alternative than aftermarket alternators.

Pros
  • Best
Cons
  • Useless features

Solved my creaking problem in the morning.

I had this strange noise when I started my truck in the morning. Found out it was the alternator bearing. Fits perfectly and has held up so far. Was a bit disappointed because it said "Made in China" on the packaging.

Pros
  • Decent performance
Cons
  • Could have chosen a newer model

Great OEM part. Damaged pulley.

Excellent OEM product. Works great on my parents' 2003 Trailblazer. I give 5 stars for receiving the original part but would like to add that the pulley on the alternator was damaged on arrival. I don't know if this damage happened at the hands of AC Delco, Revain, or USPS. This could probably have been avoided if the product had been packaged a little better (the manufacturer's box was only wrapped in paper). I was able to just replace the old pulley with the new alternator and all is well.

Pros
  • Consistent test results
Cons
  • Price that beats the piggy bank

Perfect and new for starters and alternators

This is a brand new Ac Delco alternator. It has not been restored. What you see in the picture is what you get. Very very happy with my new generator. I put this on a 2004 I6 Trailblazer, LS. 2WD. Perfect replacement and fixed my problem. Thank you again! I don't understand why Amazon can't find the right auto parts. It says it doesn't fit my car but it fits perfectly. This is the IS for the Trailblazer 2002-2008 4.2L I6 2WD. Short wheelbase. I think the long wheelbase had a different…

Pros
  • Very good price
Cons
  • Appearance
