Alternator (whats a good brand)?

[97Formula]

I checked tte dealer and they only can get a reman acdelco unit and it's $229 + core. Right now it seems I have really high volts on cold start (wondering if this is related to my strange cold start issue). Volt gauge is slightly over the line after 13 on the gauge. Volts do come down as it warms up and is consistent (stays between 13 and that line).

My current alternator is supposed to be new (toughone 91411). The warranty is done. So if anyone knows where can I get a new genuine acdelco alternator I appreciate it. Thanks!

You are better ff having yours rebuilt buy a good local auto electric place. Unless you get Bosch and a select others, most are Chinese junk. Delco would be a good choice too.

[sweetbmxrider]

Most cars run around 13.8-14.2 volts.

hook up a volt meter and really test your alternator. that gauge isn't worth jack on your dash lol.

I personally go with A1Cardone... had good luck with their stuff so far, better than stuff from advance auto, oreilys, etc.

[97Formula]

I'll see what the voltmeter says.

Meanwhile I found 3351050 and 88877260. Listed as new for $129. Is this a genuine gm part or am I taking a chance on a knockoff?

What is wrong with your alternator....?

[97Formula]

Seems like very high volts on the volt gauge on dash (on a cold start). I also have a slight RPM surge immediately after cold start (I have another thread for that).

I will have to confirm the actual volts with a volt meter later on.

[ThoR294]

it will be higher on a cold start, since its not hot yet.

Check rock auto. They typically have new acdelco stuff either in stock or it will ship direct from ac delco

Thanks....that's where I originally found these part numbers.

But if a higher voltage is ok and won't damage anything before warm-up I should be ok. I'll still try the volt meter next time I do a cold start.

Got a reman delco remy from advanced auto for 120 i believe. Been holding up fine for a year and a half

Spend the time and money and have the system tested properly. Putting a voltmeter to the thing won't put a proper load on the system to test if it will hold up to the demand of the vehicle. Don't spend money on parts you don't need.
AC Delco is a fancy name on a box. Don't be fooled.

Are you sure your battery is holding a good charge when it sits?

If after being check you need to replace. Talk with Josh. I put allot on my alt. Fuel pumps, lost of gauges/lights, 3rd fan etc. and my stock alt had issues at long idles or keeping the batt fully charged after repeated starts between hot laps. Josh had mine rebuilt to "his specs". I forget the details, probabaly up'd the amps a bit, but I never had an issue again.

Is this a suggestion that Duralast is as good as AC Delco? :bertstare:

Point proven

Yeah my GF's mom's 03 ford focus' alternator just took a dump. I was forced to do it at 7PM. Guess where we got it from? ADVANCED AUTO.

Now she's got a grinding noise when she turns the wheel all the way.... oh and its coming from the brand new alt

lolz wonder how many miles till it dies....

AC Delco is a logo. Duralast is a logo
Both of us use Remy to remanufacture. We use them for all our domestic alternators and starters as well as our new units.
If you had problems, I feel bad for ya, son, but I sell tons of alternators and starters, and yours ain't one.


I will put my alternators against anything from Napa or any other rip-off parts store that thinks a logo means everything.

Grinding noise coming when she turns the wheel, and the alternator is making noise? Sounds like a PS pump issue to me. And, surprise surprise, it's a Ford.
I don't know much about Advance and who does their stuff, so I cannot speak for the quality.

Since the OP requested info on a new part and did not say he wanted a remaned unit I responded in the context of new units only.

Remans are a crap shoot across the board. Sometimes they work like new, sometimes they are pretty close and every once in a while they don't work at all. I'm not saying auto zone sells crap parts. I think the quality on remaned parts in chain stores is pretty even across the board, However in my opinion new is the way to go if you plan on keeping something forever.

You can say I'm throwing out money or whatever you would like to say but in the end I will put what I feel like is a quality part on my car and you will do the same with yours and the OP will do with his. It is all open to opinion and everyone's individual experience.

We also offer brand new units made by Remy.

There is a difference between remanufactured and rebuilt. Remans only reuse the casing but get all new internals while a rebuilt replaces the failed parts and/or common issue problems.
Rebuilt units tend to be cheaper and offer shorter warranty.

Sure, everyone wants the best parts for their car, but I've been in this business long enough to know that some things aren't worth the coin.

[NastyEllEssWon]

whats the price difference between a remanned alt and a new one anyway? if its only like 20 bucks and youre not hurting for cash...always buy new.

[97Formula]

Ok....I finally got myself a volt meter after getting a new battery.

The reading when left sitting overnight -- 12.5 V
Cold engine -- 14.6 to 14.7V (volt gauge is still on or slightly above the 3/4 mark)
Warm/hot engine around 14V (volt gauge is between 13V and the 3/4 mark)

Based on these readings, I think my alternator is in good shape (as long as 14.7V is ok when cold)...

[LTb1ow]

Yes, those are good numbers

[MyFirstZ]

I would not replace that alternator.

[BigAls87Z28]

Suggest you have someone do a proper load test on the system so that you can make sure.
