Alternator OEM Volvo or Duralast
My old 04 Volvo Xc90 had 311k on the dash before the alternator gave up lol. Doing better than that!
Pros: high mileage
Vehicle:
Volvo XC90
Mileage: 500499 km
Autozone one here. 3 years deep going strong
Pros: going strong
Vehicle:
Acura RSX
Part number: DLG13966
Replaced the 2017 ACDelco alt with a Duralast Gold 160 Amp. Life time warranty. For 200 bucks at Auto zone. Hope this is the last one I buy.
Pros: lifetime warranty
Those alternators are damn near bulletproof, it’s the voltage regulators that crap out. If it were me, I’d keep the OEM unit, replace the pulley, and swap out the voltage regulator while I was at it.
Pros: alternators are bulletproof
Cons: voltage regulators crap out
Vehicle:
Volvo V70
Mileage: 300000 km
Right on schedule, about 7 months later, that reman also went out and I decided to pay more to get the Duralast Gold which is all new. That one lasted about a year and a half but then the bearings went out on it, but I don't think that issue was the alternator's fault because after I replaced it, I found out the Harmonic Balancer had lost its integrity and was wobbling a little. Again, not sure what caused what (did the bearings put extra pressure on the aging balancer or did the balancer go out and damage the alternator?), but all I can say is that since replacing the harmonic balancer and using the Duralast Gold alternator, I have not had any issues for over 2 years now.
Pros: lasted a year and a half
Cons: bearings went out
Vehicle:
Toyota
Got another Duralast/Autozone alternator in and this one seems to be working for now.
Pros: seems to be working
Vehicle:
Honda S2000
I went through 5 of those Durlast gold alternators (supposedly the best version of autozone's stuff) in 2 years before I had enough and bought a the Denso.
Pros: unlimited warranty
Cons: frequent replacements needed
I have a 2007 Chevy suburban and the altenator died so went to Autozone and purchased a new duralast 220.00. This worked for a few days and the battery died again. Checked voltage and only had 9 volts coming from altenator. Took back the altenator for them to bench test and they did not have the proper connections. Gave me another altenator installed worked great for 2 days. This new altenator was also not working and was given a third altenator.
Cons: worked few days, low voltage, multiple failures
Vehicle:
Chevrolet Suburban
Duralast 11120 (if that's what is on the invoice) doesn't have a lot of great reviews...
Pros: null
Cons: not great reviews
Part number: 11120
It was in fact a Duralast dud! One more example of a “new” alternator being broken out of the box.
Cons: dud, broken out of box
Vehicle:
Hyundai Elantra
