I be back
I love 1A auto they prices are very affordable and I got my part in 2 days, the only thing I don't like is the fact that they have a location about 30 min away from me and I can't pick my parts up, I would recommend 1a auto to others

Alternator makes a weird whining noise
I have just installed this along with a brand new idler pulley and serpentine belt so I have been able to narrow the noise to the alternator itself. It sounds like a super charger spooling. I did some research and it appears that these alternators do occasionally make this noise and it doesn’t harm the alternator it’s just annoying.

Alternator installation
Thought your video was good. You should tell the customers in your video that a serpentine tool should be used to reinstall the serpentine belt.

Exact match as stated.
Upon reviewing the YouTube video it is important to make note that although the video advises to move the fuse block so the bottom bolt of the alternator can be extracted. In actuality you must also remove the fuse block mounting bracket as the bolt can not be extracted unless doing so. I used an off set 12mm to remove the 2 bolts and then the bracket it self and once the bracket was out of the way the alternator bolt easily came out and I was able to replace it. One last word of advise, it might be a wise investment to purchase a long 14mm wrench in order to take the pressure off of the tensioner pulley. I used a short wrench which is all I had with another long wrench over the end to give me additional leverage and quickly found out it was no easy task. Having a second set of hands to get the belt back on is the best advise I can offer as it was very difficult to get back on. In the end it all worked out and the battery light was no longer on. Car has been running perfect for almost 2 weeks.

Part great, Video helpful.
Part came in early. Working well. Video was helpful, but definitely not as easy as shown. Serpentine belt wrench is the way to go to create enough slack from the tension. Needed another set of hands to get belt over alternator. Overall, done in under an hour. Not bad for first time. Thanks, 1A.

2005 Nissan alternator replacement
As usual, 1aauto has the best in class prices and the installation videos are above and beyond. Thanks to 1aauto, I might be able to pay for my kid's college instead of paying a mechanic for repairs.
Thank you 1aauto!!.

Great product!
So far so good. My husband and his buddy removed the old alternator and installed the new one fast. Alternator fit perfectly and seems to be a good product.
