Rated 5 out of 5 by Excellent product Great part. Direct replacement for original alternator. Currently performs like new. September 10, 2016
Rated 5 out of 5 by Best Price I searched every auto parts companies both instore and online. I am so impressed with PepBoys website !! Not only did I get a great price by ordering online (same day in store pick up ) , the website also gave me instructions on how to install the alternator saving me a great deal more money!! September 6, 2016
Rated 5 out of 5 by Good price and works great My 97 Jeep Grand Cherokee Limited (ZJ) started giving me low battery warnings. Checked the voltage while running and alternator showed in the mid 12s. Took it to a local parts store and they verified the alternator needed to be replaced. My model of ZJ came stock with a 136amp alternator and most of the part stores were trying to sell me a 90amp version which is what came on some of the lower ZJ trim models. The 136amp the other local stores sold is for the v8 which doesn't has a different number of grooves in the pulley than the I6 in my ZJ. I know I could swap pulleys, but why should I have to when there are ones with the correct number at pep boys? I found this 136amp version on Pepboys website and used one of the online coupons they normally promote and got this for $40 less than most local competitors. Installed it myself and it showed a charge in the mid 13s, so it is working correctly now. I believe the alternator I replaced was the original, so 20 years/130k miles isn't bad. I can only hope this one will last as long or outlast my ZJ. The warranty is excellent too, so I'm happy with it. September 5, 2016

Rated 1 out of 5 by Alternator melted afer 20 days! This remanufactured alternatorwas a pc. of junk! Purchased on 07/26/16 and melted down on 08/14. I was 180 miles from home when it fried. Left me stranded on the side of the road in 100 degree heat for five hours. Took out the serpentine belt as well when it seized up and melted. Cost me $478.00 an almost heatstroke to get going again!

Rated 5 out of 5 by Exact replacement! Replaced my defective alternator with this rebuilt unit and it worked like a charm. It was a perfect fit and the installation went smooth. It came with a great warranty, and the price was right! I purchased it online and picked it up in my local store. Smooth transaction. August 8, 2016
Rated 5 out of 5 by Satisfied Bought this for my 2001 Camry. Being "top" mount, it was easy to install. Only 1 minor flaw, the calibration in "mounting" was very, very tight. Had to slightly "tap" into place. Tightened the belt, 1/2" play as required by manufacture and it works very well. August 5, 2016
Rated 5 out of 5 by No more grinding bearings Excellent product and great on-line purchase with discount. Easy to install on my daughters Jeep Liberty...item was ready for me when I got there about 15 min after I ordered It online.. July 31, 2016
Rated 5 out of 5 by Solid value With my wife having starting problems on my 17 year old car, I checked the standing voltage on the newer battery which read around 11 VDC. Got it started and read 11.3 from the alternator. It was a holiday weekend so I checked several chain stores rather than my usual family-owned parts store. PB not only had it in stock but gave me 30% off for signing up for their customer rewards program. The alternator has performed flawlessly for three weeks of daily use. July 31, 2016
Rated 5 out of 5 by PEPBOYS MY FAVORITE AUTO STORE The alternator worked right after installing, PEPBOYS is good enough to me. Technician who served me at the Story Road was so nice when I've got confused Buying on PEPBOYS webpage, paying at the store. July 30, 2016
Rated 1 out of 5 by Bad Product I bought it 01/15/2015 and now is dead 03/12/2016 March 12, 2016
Rated 1 out of 5 by Dead after 12 months Installed in my Freestar last year and now it's dead. My battery light use to come on intermittently, but I always thought it was something else since my alternator was new. I was obviously wrong. January 29, 2016
Rated 5 out of 5 by Great buy! My old alternator was growling at me as the bearings were wearing out. After replacing it with this re-manufactured unit, the noise went away, and my battery stays nice and charged. This affordable part is a great choice, and the warranty is good assurance as well.

Rated 5 out of 5 by Works Great I needed an alternator to replace my original one that had 156,000 miles on it, and this remanufactured unit works great. It appears to be a high-quality rebuild of the same type of alternator as my OEM unit. October 28, 2015
