Rated 4 out of 5 by The product was exactly as advertised The alternator was in excellent condition and fit like a glove. It works great. September 3, 2013
Rated 1 out of 5 by COMPLETE JUNK First one lasted 11 months and 20k miles before the bearings went out. The second one straight out of the box had a output voltage of 13.6-13.8 VDC causing a low battery light. Where is the quality control? Wish I would have paid the $50 more to buy it from the dealership to get a working/ dependable product! August 30, 2013
Rated 5 out of 5 by Pro-start alternator This alternator fit perfectly upon installing. Couple hours of work later, my car was running again. I especially like the warranty it comes with. July 17, 2013
Rated 4 out of 5 by Works good. Have it running in the car for about a month now, and so far its been good. Fixed the issues I was having with the old unit. July 8, 2013
Rated 1 out of 5 by Unsteady voltage, no output when hot Voltage fluctuates 2 times a second from 13.3V to 14.1 V (13.6V average) causing all lights to flicker & pulsate. Alternator has NO output whatsoever when the unit is hot for up to 2 minutes after engine start. When cold the alternator kicks in immediately to 13.6V to 14.1V. I can't rely on this thing.
