  • This fit my 08 Hyundai Accent
Style: 13973 Alternator
I installed this unit in my 08 Hyundai Accent. It fit perfectly and I had no issues replacing the original unit. So far, the alternator works well. Update 7/1/25: Well, it worked for several months and thats it. My car is pretty basic and contains all the factory specs. My OEM Hyundai alternator lasted from 2008 to late 2024, and and a few days ago this alternator left my car stranded with a ~$300 tow bill. The problems started as strange behavior with dashboard lights and then after turning off the engine it wouldn't crank again. At first I blamed my brand new battery, I jumped the car to see if that's the issue. The car fired up and then maybe 5 minutes later all the electronics started to malfunction. This happened each time the car was jumped. Basically the battery gets charged enough to start the car but the alternator is not able to maintain a charge to power the electronics. Another strange symptom was that the RPMs gauge in the dash became unresponsive. After towing the car the battery is totally dead. Thinking the car is basically done, I did some research and all the signs pointed to a failing alternator. 7/6/2025: This is the final update. I've switched the star rating back to 5. The reason for this change is that after investigating, the catastrophic failure was not due to the alternator but there was an installation error ie the ground wire bolt was not tight enough. The wire eventually failed to make a solid connection and the car couldn't get a charge. After fixing the ground, recharging the battery, and several days of checking the voltage at idle and driving; the alternator has shown consistent voltage levels within the proper specs: over 14V while driving, >=13V at idle when there is minimal load placed on the car (AC on medium, basic headlights, radio). For the size car and alternator amps I've read it's normal for the Accent to have voltage drop at idle under heavy load below 13V but that 1500+ RPMs is where you test if the alternator is properly carrying the heavy load. While driving I cranked the AC and the voltage never dropped below 14V at roughly 2000RPMs. All tests have thus far past since the loss of power issue. ... show more

  • It works.
Style: 13980 Alternator
Today, July 1, 2025, I installed the alternator. It seems to work perfectly. It is charging the battery at 14.56 volts, a bit high as a charging voltage, but acceptable. Tne new alternator seems identical to the old unit. One needs a shoe horn and an octopus as a helper to get this alternator in a Honda. It can be done but just getting the serpentine belt back on properly took 20 minutes because there is no space to get your hands in and position it properly. It is now in a 2005 Honda Accord EX with 260,000 miles on it. If it blows up, I will post another review. I liked the fact that the alternator came with a document of how it was tested and passed several inspections. ... show more

  • Better than anything locally
Style: 13981 Alternator
I was so ready to leave something negative because it was a day late and with a down car a day is tough. But this is probably the best alternator I ever installed. It's 100 % brand new and a perfect fit. Better than anything I could get locally for 1/3 the price

  • Always charge up a low battery
Style: 11069 Alternator
It fit just like oem, fairly easy install. Battery was charged up the day before installation. It charged perfectly while running, no noise during operation. I'd buy again.

  • Cheap Alternator Replacement Got me out of a bind, but...
Style: 12913 Alternator
This alternator is a cheap replacement for a Ford F-150. It works okay for now. It may have parts that have not been replaced or meet Ford standards. This alternator charges fine, but the waning light and chime continue to come on intermittently while driving. Upon further diagnosis, my mechanic said it has a faulty diode. He said some of the cheaper remanufactured alternators are not complete rebuilds, and do not replace every component, and may cause problems in the future. I'm giving this product a three-rattling because I was in a bind when my OEM alternator lost its voltage regulator. We just had a major storm blow through town, and half of Houston was without power. Ford wanted $500 and a two-week delivery. O'Reilly Auto Parts ($300) was shut down due to the storm, but Amazon was able to provide the next-day delivery and got me back on the road for around $130. Cheap alternator replacement got me out of a bind and working fine, but may not be able good long term solution. ... show more
