Alternator OEM Mazda or Duralast
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
I was able to remove/replace the alternator on my Mazda CX-5 without removing any parts as has been mentioned.
Pros: remove/replace without removing parts
Cons: extremely difficult, very tight fit
Vehicle:
Mazda
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
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 want to hear an opinion on getting a duralast alternator and popping it in my n52 I have heard very mixed things about these parts some work fine others are trash.
Cons: mixed reviews, some trash
I started having problems like my alternator was going bad again so I replaced it with a duralast alternator part number DL2618-6-11 because I had a lifetime warranty on it and it still didn't fix it so I was thinking it may be a wire shorting out was playing around with the wires that go to the alternator and the plug on the back that goes from the alternator to the PCM and it's started charging again ( I guess it finally connected the electricity) so I replaced the plug on the back of the alternator. It fixed it work for about a month then it happen again check charging system battery light on and battery going dead so I was done. I took it to the Ford place they wanted to replace the other side of the PCM to alternator connector which they did and the alternator so I got another AutoZone lifetime warranty alternator and when they did that they said everything is charging and running like it is supposed to be but your PCM is still throwing the battery light and check charging system because your alternator is charging at 14v and for the PCM to cut the light off it needs to be at 14.6 v. So they wanted to put another alternator on it because they said the alternator from autozone the voltage regulator wouldn't let it go to 14.6 volts. The car runs and drives and doesn't have any problems I just hate the light being on to be honest I have spent hours on the Internet trying to see if it's just these AutoZone alternators that aren't letting it get to the volts the PCM wants or not haven't found anything.
Cons: insufficient voltage output, battery light remains on
Vehicle:
Ford Mustang
Part number: DL2618-6-11
Duralast are shit alternator. See it time and time again people buy them and have more problems afterwards.
Cons: poor quality, causes problems
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
