Alternator VALEO or Duralast

I went with a Duralast Gold(90A) which never gave me a issue. If I had a oscilliscope im sure it had good output.

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

Cheapest for me was a new Valeo unit from Rockauto. Cheaper than Turner too.

+1 for Valeo. This job wasn\u2019t fun.

I’ve had two D/L Alternators. Each has lasted 3 or 4 years.

I bought a new Valeo alt cheap because this part was broke. After days os scouring the internet I found two sources, but the would NOT retail the part. They only supply rebuilders in bulk.

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.

Mesmo um Valeo novo está caríssimo, pede mais orçamentos.
