For 2001 Infiniti i30

Are the alternator sizes different between 125amp vs 110amp? There is also 100amp that autozone sells.
Rockauto lists 100amp and 110amp.

When I state size, what I mean is the product size. Does either fit my car the same?

Also which brand should be recommended?

So the OE is currently 100 for my year/model?

Thank you for your input. I'll update on what happens next.

Hitachi seems like a reliable product from my experiences. But should I go with OEM for alternator?
If so which site can I go get one?

If I recall Hitachi is OEM, go to Pep boys, Auto zone, O'Riley's etc and get one 110 with lifetime warranty. You done for life...

I respect your point of view but from what people say is that getting those remanufactured parts from those parts stores can be a pain. This is my main car so I need it for work and can't be changing parts often. If this was my secondary car the life time warranty would be a great selling point.

I'll probably stick with the Hitachi. Thanks for your input.

rockauto.com only.....Hitachi or Denso.....FTW! Looks like 100-110 amps is the norm...You running an EMS Maxima? If not a 100/110 amps will work just fine...

I've read some posts that stated people had fit issues with some aftermarket brands. If so, then oem is the way to go for fit.

However, since these are rebuilt, it seems like brand means nothing as long as it fits. If I knew a cheap one fit, I myself would buy it and have it gone over at an electrical rebuilder and know for sure it's been rebuilt thoroughly.

My point is these are rebuilt......so why pay a high price for an unknown quality when a rebuild shop can give us the certainty we need.

All the different amperage alternators are supposed to be the same physical size so they will fit in the space Nissan created. The alternator for the 2001 is rated as 110 amp. The 100 and 125 alternators were on older models in the 1990's. I think it was 1998 when Nissan settled on the 110 amp model.

I ended up getting my alternator changed at a local shop that specializes in alternator repair. I'm super busy with work and didn't have time to work on it.

Shop owner told me they had to remove radiator and some other stuff just to get the alternator out. So the car starts and drives fine.

BUT, my AC doesn't work. Did they F up something along the way? I've never worked on AC component before so I have no clue
what they could have done wrong other than not connect the wires back but it looked like they did. Any ideas?

This is the reason why I hate having people touch my car. The stupidity that can happen is endless.

Yes, the a/c compressor and alternator are on the same wire hareness. It's possible that he disconnected the a/c wire and forgot to put it back.

110 amp was factory for most if not 5th gen maxes, the 125amp are of unknown origin as are the Bosch remanufactured with **** tons of complaints and failure rates. I've yet to see reviews or try the 125 amp. i took what i had (looked rebuilt or aftermarket 110 amp) to a trusted proven local starter/alternator rebuilder and had them upgrade mine to 118 amps ( cost me a little over $80 USD). I left my radiator in, infact my radiator gives even less room as it's an aftermarket all aluminum 2 row and 3 times thicker than the stock one. Also a good chance they removed your A/C compressor instead of zip-tying it out of the way, if they did, did they evacuate and flush the system and re charge? or is contaminated and grinding up the innards of your compressor when you try to turn it on? (though it would have to pretty heavily contaminated for that to happen)

Thanks to the replies. Had the shop recharge the AC and now it works.

i30 is back on the road running great.

I just had my old one rebuilt last year back to factory 110 spec. so the casing is the same, and no fitment problems (aside from the PITA that is actually removing and installing the thing in the first place). Good to hear you're back on the road.

Hell I've got 3 junkyard units in my warehouse (Garage) that have all been tested good!
