ACDelco Gold 335-1196 Alternator

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.

2011 Chev. Suburban 5.3 literVery 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.

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!

Everything is working well

Box was torn up......plastic rear shield was broken. Your shipping dept. needs to ensure security of the product when its shipped!! POOR, POOR product packaging! This is a 200.00 alternator, not pajamas! I have no choice but to have it installed......I NEED MY VEHICLE BACK! Might work, might not due to the condition of the packaging!

I bought this Alternator to replace the original OEM factory alternator for my 2008 Chevy Tahoe that was giving the check "The Service Battery Charging System" message. I will say, it was delivered on time and VERY well packaged! Installed myself and required minimal mechanical skills just a few tools. So far has worked flawless. No check the charging system so far and its been about 3 weeks in up and down weather conditions when this message would come up at least 3-4 times a week since changing. NOTE: If you haven't changed your serpentine belt in a while, do it while you have this one off and it's super easy. Hope this helps.

Purchased this alternator for a 2014 Chevy Silverado 5.3L V8 due to stock alternator failure. Received replacement and positive wire connection was in a different location than stock unit. The mounting bolt of the positive connection was so close to the intake manifold I was worried it would short circuit to ground. Also the other two wire harnesses connection was too short to connect without make adjustments to wiring harness. Sent back and replaced with OE part number 84143540 and was a like for like replacement. Easy install and fixed red battery light on dashboard.
