Rated 5 out of 5 by Works great, easy fit My battery was not holding a charge when the car was parked for more than a day. Thought another battery had gone bad. But then I started having some other issues and hearing a whine. Figured the alternator was going out. Got the Prostart Alternator at my local PepBoys and it fit perfectly. Took less than 10 minutes to install. New alternator works very well and looks just like the original. My problems are solved. Battery stayed charged, all car systems working perfectly... YES.

Rated 1 out of 5 by poor quality It lasted 13 days, 123 miles then died. I got a replacement, went 2 miles shut off the engine, picked up a pizza, Stopped charging as soon as I started the engine. Started charging after driving about 10 blocks. Low charging rate, with lights and A/C on, dropped down to 12.5 volts, lights dimmed when stopped. Took it back, got a refund, bought an A/C Delco from a local Parts store....worked perfectly. Neither Platinum alternator was in stock and had to wait a day for each to get them from another location. Web site specs says "MFG. -DELCO". Sticker on the unit says "made in Malaysia". Stay away from these... June 7, 2016
