vs
Alternator GENERAL MOTORS or Duralast
Reviews
Been running a duralast in mine for about a year no problems.
Pros: no problems
I'm selling a GM alternator, mount, pulley, and plug. It's the Duralast Gold Delco 12 SI 94amp, just warrantied it. Hasn't been on a vehicle.
I just purchased a 180amp Duralast New for my X about 2 months ago. The Duralast has done me well so far.
Pros: done me well
The only good thing about buying a duralast is it'll be the last alternator that you have to *PAY* for. But it def will *NOT* be the last alternator you install in the truck. Lol
Pros: last alternator you pay
Cons: frequent alternator install
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
All I could recommend is stop buying the autozone/duralast alternators. Buy a good brand, ie Denso, Delco, Motorcraft, etc. and return the duralast one outright for cash in hand.
Pros: return for cash
Cons: prone to premature failure
Duralast..... if you want to get really good at changing them.
Cons: changing them
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
three alternators in a Cadillac, even "new GM" are remans, only way to get a new one (never installed, made of new parts, new for you) is to buy a new car.
Cons: multiple failures, poor reliability
