ACDelcoGold 335-1086 Alternator

Really nice looking alternator, very simple install. functional & good voltage power, worth the value. Kepps battery charged very well. Fits perfect on any Chevy with a 105amp alternator.----2003 Silverado 1500 4x4, 5.3 LS----1 - Pop open beer...2- remove air filter3- loosen the belt ( belt tensioner ) ( 15mm )4- remove the 2 screws through the front ( 15mm )5- might need to use crowbar to lift out old alternator / put in new one6- unplug the 2 plugs in back7- replace with new alternator ( might need some massaging to put in )8- do step 6 -through 1 to finish install

Fits and works great on my 04 Lly duramax!

I was pretty impressed. Usually when you buy something used or remanufactured you don't have the best luck sometimes and they look like you know they've been beaten on or something. This thing look brand new ,from install to today's date. This has had a stellar performance even through the brutal winter so this was a pretty good purchase. Very satisfied with the quality and the ease of install

The original alternator in my 2001 Silverado 5.3 went bad so I checked what my nearby parts stores had available and was not impressed. All they had were their respective in house brands of alternators, all of which were remanufactured, and the prices were $150-$250!!! I have another truck so I didn't need the part right away so I went to Amazon and was shocked to see a brand new ACDELCO "Gold" alternator (made by Delphi, the OEM) for under $100. Stay away from remans especially ones that aren't even OE to begin with. Unless you need it right away its insane to spend double the amount for an inferior product that isn't even new! The original alternator lasted 22 years and almost exactly 200,000 miles. That's enough convincing for me to stick to the OEM. Even though its an easy job I'd prefer to not have to replace my alternator again for as long as possible.

This alternator worked well while it lasted, but 2 years and 5 months after it was installed it failed. It only output 11v, constantly killed the battery and left me stranded on the side of the road. I was expecting at least 5 years out of this since it is a GM ACDelco alternator. The original alternator it replaced lasted for 18 years. I guess when they build the cars they use better parts. Funny that it failed right after the 2 year GM warranty. I decided to buy an Autozone Duralast alternator that has a lifetime replacement warranty if it ever fails. I also opted for the 145Amp. The original and this one is a 105AMP.

Exactly what I needed to replace a defective alternator on a 2001 Chevrolet Suburban 1500. For this application I did have to have an adaptor wire to connect the four wire original to the dual plug on the alternator.

Works

I read some reviews where there were complaints of the alternator making a whining noise. This may be normal for new alternators until the brushes are seated. The alternator I installed made a slight whining noise but after 4,000 miles since installing it, I no longer hear it. The original alternator has 225,000 miles on it and was still working but as a "playing it safe" I decided to replace it because I didn't want to break down on a deserted highway somewhere between here and there.
