Alternator OEM Volvo or Duralast

Possibly the alternator, mine did that so I bought a brand new duralast gold alternator and it solved so many of my problems.

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

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

I know my 2005 S60 alternator has a chip in it that is necessary to talk to the car's ECU so be careful buying aftermarket.

I have a 100A alt from a 900 series and it keeps me powered, but barely. And if I have the stereo loud + headlights and fogs and a/c, I get belt squeal.

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.

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

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.

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.

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.
