Acdelco 335-1196 Professional Alternator

This a cheap quality alternator that did not last 1 week

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.

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

Perfect fit and works as properly pumping out 14.5 volts

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.

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
