so my car wouldn't start this morning. and after a few check list and jump the car few times. we figured that it's probably the alternator that's needs to be swap out....anyone have any experience of changing new alternator? how much does it cost with labor?

need answer ASAP

thanks!!!

 

mm....anyone....?

 

are you mechanicly incline? check out youtube

 

Have you already ruled out the battery and starter as the cause of the problem?

If you're sure it's the alternator, you're looking at about $345 (MSRP) for a new OEM one. You can buy one online for $250 but a dealer probably isn't going to discount it that much. Or, you can get a remanufactured one from your local parts store for around $170.

Alternators aren't that difficult to install. I would think a dealer could do the job in an hour or two and the bill would be close to $500. If you do it yourself, you're looking at half that if you buy online.

 

so Im going to give my battery a check tmr. and I found that when i turn my ignition to ON, there's lights on my dash, but weak, and sometimes blink a little. can that be the alternator then? I'm so stressed out....

 

are there better aftermarket alternators with more amps??

 

It's more likely your battery than your alternator. Get it tested.

Last I checked, there are no bolt-on aftermarket high-powered alternators for the G. Custom made only.

 

Yes there are. I got mine for my Accord from www.qualitypowerauto.com. Check out www.mechman.com as well. You are looking to spend 350 - 500 though and if you don't need extra amperage there is no point in getting one. You need to check your battery at first and see if that is the issue.

If it's not and if you're not running any extra electrical equpiment like an audio setup, then you don't need more amperage, it's just not necessary. Even with an audio setup, if it's nothing crazying, like 1,000w or less, generally the stock alternator will be fine with an upgraded battery. But if you're running thousands of watts, and I mean actual RMS and true ratings, not what Audiobahn states, then yeah, a beefier alternator with more amperage is recommended. But I don't see someone running that much power because the trunk, even in the sedan is not that large, they're decent.

 

yea your right, i was recommended doing alternator i got a 1200 amp hooked up with 800wat sub, i still have stock battery, gonna change to optima yellow top see how that goes, i was also told and explained how a capacitor actually is worse and puts strain on the alternator. is this true??? how many amps does the g35 coupe alternator have or handle?

 

I believe our stock alts are 110A. There is lots of talk about caps whether they work or not. If you're trying to solve voltage problems, dimming, etc, the capacitor will not help fully. It would be more like a strain. I'd only recommend using only if your electrical is not having any problems because then it will act to assist, not to try and fix.

Honestly, I don't think you need an upgraded alt with that little power. If the Odyssey PC1200 if it's not much more than the Optima. Optimas are good batteries, though I haven't used them. I love the Odyssey, great daily battery. People recommend Kinetik but those are better used for when using the audio system while the vehicle is off. Yellow top itself will be fine. Do the big 3 as well (not sure if I mentioned it earlier).
