ACDelco Gold 335-1196 (88878264) Alternator

2011 Chev. Suburban 5.3 liter Very pleased. Alternator arrived on time, well packaged; and completely intact. Excellent price for a NEW ACDelco alternator. It is the exact replacement for the OEM original I was replacing. Follow the many videos to be found. Installation is very easy. Have patience, if installing new serpentine belt. Because it is new, and not stretched, it will be tight; but the 'ah-ha' moment will come quickly. DO, make a diagram of serp belt 'routing'. No worries then of 're-threading'. Also included is 1-800 tech help line #. My call re: torque pounds on mounting bolts, (41lbs.), was returned and answered within 15 mins.! My initial questions were, 'what is the difference between this alt. #335-1196 & OEM #25877026?' First, about a $100.00 less than OEM. Only difference, (to the best of my knowledge), is that ACDelco. #335-1196 is made in Mexico; which makes no difference to me. It is, (and very clearly marked), a NEW ACDelco alternator.I do not want any other brand in the Subbie. #25877026 , (I assume), is made in U.S. "Professional '#335-1196 is ALL NEW ACDelco parts, fits perfectly, good warranty; and charging like a mad dog. I highly recommend this alternator. Hope this is helpful.

Genuine GM. New not reman. The one i got was stamped made in USA. Used on a 2011 2500hd truck that has very high current draw while plowing snow. The original Alt. Lasted 256k miles and 15yrs! Why use anything else than AC Delco. Yes you can save $100+ ordering a Chinese reman. Good Luck with that. I also replaced the Belt, tensioner and idler the result is silent smooth operation.

It was easy to install and worked great for 3 weeks. Then the car died and left my son sit in the middle of nowhere at 10pm. After finally getting it towed home 2 days later, it had to sit because my family and I were going on vacation and had booked a non refundable condo. Finally got home today and was able to check it out. Found that the alternator is not charging enough volts.

Very nice thanks GM !

Was a littlle concerned at firtst, Regulator frequency was causing volt meter to fluctuate rythmically. Stabilized afted a few days and has been stable and working well for about six months now. Burn in period I hope. And yes, the battery was charged up prior to alternator installation. Satisfied customer.

Everything is positive. All the pieces fit no issues getting it in. No problems firing up light went out like it was supposed to. I reset everything. I’m good to go.

Would highly advise going against this product if your doing it for a Chevy 2014 Silverado 5.3. Bought to replace my alt, while it does in fact alike with the item ID part, they are not the same as the original alt in your truck. It fits in there, however the electrical plug that attaches , is in the back of the alt, which faces the manifolds and is barely any room so you cannot use your factory harness that goes to the distribution fuse without possibly making your own wire to connect from the back to the battery. However, you can find GMS exact replacement by just finding the part number and putting it in. 100% replacement on the other no issues. If your gonna do this might as well go ahead and clean throttle body, replace air filter if need to. Also the part in the picture is false, it’s not black but metal unlike the one shown and your original one. Also this was made China. It comes with the box that says from acedelco Mexico, but then has made in China on it. Wouldn’t not recommend for 14 Chevy Silverado 1500

OEM for great price. Perfect fit for my 08 Denali!

Brand new as stated, not reman'd. Nicely packaged, quick delivery. No complaints.

Perfect fit and works as properly pumping out 14.5 volts

Not happy. After nine months died. Only one month warranty from what I can see.
