vs
Alternator GENERAL MOTORS or Duralast
Reviews
The OEM alternator is only 55 amps and costs nearly $400, which is stupid expensive and wholly inadequate for off-road lighting, audio amplifiers, and other additional accessories so I decided to go with the CS130D GM alternator, purchased for under $100 new (no core charge) and has a 130 amp capacity.
I'm getting 14.8v from the upgraded alternator at 700rpm and maintaining 14.2v when every possible accessory and light is turned on at idle.
Pros: 130 amp capacity, under $100
Cons: OEM is expensive, inadequate
For hpw old your car is, and the price of these boys in the photo, id go to your local autozone and get their alternator, simply because they come with a lifetime warranty
Pros: lifetime warranty
Vehicle:
Acura TLX
I'd just get something with a warranty. I've been using Duralast from Autozone for the longest time and haven't had too many issues
Pros: warranty, not many issues
Just bought and installed a Duralast Gold from Autozone last week for my '07 9-5. It has a little whine at 2500 RPM but works better than OEM. Has a lifetime warranty and it's 100% new too!
Pros: works better than OEM, lifetime warranty
Cons: whine at 2500 RPM
Vehicle:
Saab
I’ve never had an issue with a Duralast starter or alternator. However, honestly, I probably wouldn’t put one on my Lexus. I’ve generally shoved them into cheaper and simpler cars.
Pros: no issues with Duralast
Cons: wouldn't put on Lexus
Vehicle:
Lexus IS
Autozone will give lifetime warranty on certain (duralast gold maybe?) alternators. I got the replacement very wet (dumb), and it died while I was driving.
Pros: lifetime warranty
Cons: died while driving
I burned up 4 of the duralast Gold GM 12si alternators while they were still under warranty, if I had to venture a guess it would be they don't like high RPM . I removed them from two of my samurai's and went back to stock, haven't had a problem since
Cons: don't like high RPM
I went through 3 duralast nators on my wife's exploder before I got one that lasted more than 6mos. Aftermarket everything has mostly gone to shit.
Cons: lasted less than 6mos
I have experience with both shitty Autozone Duralast alternators and I would not purchase them.
I have shadow codes for my water pump because of it, and my voltage is not high enough at idle, and never surpasses 13.5ish volts. It whines loudly, and it doesn't make the same power as my last alternator contrary to the ratings.
Cons: whines loudly, low voltage
The refurbished Duralast alternator has worked fine for a few months but the last month I started to hear belt noise and assumed it was related to the alternator. The last couple of weeks I would smell a new unknown burnt smell that smoked like either rubber or electronics which has led me to wonder if the battery/alternator fuses have gone out.
Pros: worked fine for months
Cons: belt noise, burnt smell
