ricky, I bought the gates kit(assuming it's the same one). I don't know that mine claimed it had ACDelco parts but I do remember the Gates belt was good quality, but the water pump, idler pulley, and tensioner pulley were JUNK, very cheap parts. Each were manufactured in a different country(don't remember which countries....china, etc.). They were aluminum IIRC(except the actual wheel part of the pulley is plastic, like oem IIRC) but they were about half as heavy as oem(cheap material) and my water pump failed immediately and needed replaced. I mean immediately like withing 1,000 miles. I replaced it with a duralast from autozone and it was much better quality. I also have a squeaky bearing(either tensioner or idler) it wasn't there until I did the work then was there right after. I would not buy that kit again.
