Thank you very much for this video. I was able to pull my first alternator out of my 2003 Nissan Altima. I was able to cheat a little. I took out the top and bottom bolts because I couldn’t get the belt to slide off even pushing on the tensioner. The bottom bolt I had to finish with a 14 mm crescent wrench. I was able to pull up the fuse box just enough to get that bolt to slide out because I didn’t have the right tool to take out the fuse box bolt. Then I used the pry bar to push to the alternator out and as it dropped the tension in the belt released enough to pull the alternator out without having to remove the belt from the pulley. This video was extremely useful for a backyard mechanic like myself

if you have a 2005 you will have to remove the two bolts holding fuse compartment as there wont be enough clearance when backing the lower 14mm bolt out because it will hit the metal frame holding the fuse box...just did it today...

Thank you! This video saved me $200 in labor. We did have to take out the coolant overflow and the entire fuse box to get that long bolt out but it was worth it!

For those saying you need to remove the fuse box and coolant container, you really dont have too. I also thought I was going to need to do so, but if you pull the fuse box up enough, it gives clearance for the long bolt to come out. Then again I was being a bit lazy to take another 5-10mins to remove everything lol. But great video as always!

Posting some feedback for others, as I just spend ~2 hours working on this. First, the video is supper helpful. The tools needed are 100% correct, and the order of things to do is correct. However, if you have an older car, and depending on the model, here are the things I ran in to while taking on this task. -- 2003 Nissan Altima 2.5 1. Check the wires that feed in to the alternator. The tape and the plastic wrap that holds the wires for signs of damage because you want to fix that. ASAP. I re-wraped mine in high-temp tape they use for HVAC. The plastic and the electrical tape will only last so long. 2. In the video the presenter mentions that fuse box being in the way, when yes it is. In fact the bracket was completely in the way on my car, and the bolts were rusted to the bracket. After a lot of WD40 and patience I was able to get the bracket loose enough to wiggle it out of the way get the bottom bolt of the alternator out. 3. The space you are working in is super tight. Have on hand some pipe to use to as a breaker bar to break the bolts loose if needed, or you can use that trick with open ended wrenches and link them for leverage. 4. Consider some velcro or zip ties to secure the belt in a place where it won't move out of place and fall off the other pulleys. I lucked out because I had something in my box. If you don't, it could move out of place and now you need to get under the car to see the back of the block, or really skinny arms, flashlights, and mirrors on the floor to see what you are doing. 5. On my car, the break light and battery light came on (no check engine) when I had the battery checked at the auto parts store. When I replaced the alternator, all the red lights went away as the computer reset. Keep in mind, some lights could reappear later on, and you will need to have it checked out. The computer in the car will do weird things when the power is not consistent. Sort of like when HAL in 2001 a space odyssey. Have fun folks!

Idc what anyone says, these guys are the best. Great instruction videos and parts.

Thank you my 17 year old doughter changed it.

After viewing this KZfaq video my neighbor and I did my 2002 Nissan Altima today! It worked out beautiful!

Cheapest part and easiest instructions possible! Replaced mine in my 2005 Nissan Altima. Probably saved well over 100 dollars. Thank you so much for these videos!

Can't thank you enough!! Ordering the alternator shortly. 1A has saved my butt more than once!!!! Thanks to you I can do it myself.

Video was very helpful especially when it came time to move the tension idler. I thought I was going to have to loosen it and then readjust...very helpful! I would recommend removing the coolant overflow container (2 bolts), then lift the fuse compartment and finally remove the 2 bolts holding the fuse compartment bracket. This takes only 3-4 minutes and gives tons of clearance for the long bolt and easier access to the tension idler. No burns or busted knuckles this way ;-)

found best price for new alternator from 1A Auto, and followed video exactly as shown, finished in about an hour. Tested with multimeter at battery, and it charges great! Thanks 1A Auto!!!

Hey! Thank you so much! Really saved my bacon! I had the new alternator on, and the main bolt in place, but the belt was too tight for me to get the thing in place for the second bolt! I was freaking out. The first video I watched about adjusting the tension did not apply to my car. Following your instructions turned out to be super easy! I thought I was going to have to loosen and then re-tighten something, but I just levered that wheel down and moved the alternator into place! God bless!

Thank you for this. It helped me get out of an emergency situation and back on the road in an hour!!

thanks for this video today I was able to change the alternator of my sister's car following all the steps, keep making videos like this for those of us who know nothing about mechanics.

Thank you guys you helped me figure out how to take out the belt I was struggling with it just changed my alternator today on my 05 :D

Great vid. After forgetting a wire, my car wouldn't start and gave p1760. Attached the missing wire, cleared the code. All seems well. This fixed my problem with the belt vibrating loudly every so often.

You guys are awesome man thanks! I would've ordered from you guys but you're out stock lol great video, thanks again!

replaced the alternator in my '02 sentra se-r 2.5l after watching this video. ive never done more than changing a tire but i had the new alternator secured in under an hour. thanks much :)

It's already been said but here is one more Great demonstration!!! You made what I thought was going to be difficult very easy Thank you

Very well done. Thanks for the video. It helped a lot!.

Great help guys. Thanks a lot for your videos.

video is definitely helpful however I now have a new enemy a serpentine belt that was the hardest thing to put on thank you for the video it saved me a lot of money and time

Thank you 1A Auto Parts. i will always order from this company. i just installed my new alternator and soon will post a video on how it looks.

Very helpful! only on a 2003 Sentra SER spec V the tensioner bolt is down a bit farther and the belt was a little tricky to get back on by myself, Had a friend help hold the back part while i released the pressure on the bolt. Other than that great guide!

Ah, this unfortunately did not solve my problem, but this was a great walkthrough on how to remove & swap an alternator. Thank you!

Currently watching because I'm about to help my mom do hers.

Thanks for your video that it helped me to fix my car by my self.

Super helpful, man. Auto guy was gonna charge me $450. I'll check out A1 when I need parts going forward.

Thank you for this video. it was very helpful.

Just used this video to get my car back on the road tonight. Saved me a tow bill, repair bill and my wife’s nerves. Thanks!

Thank you I changed my 1st alternator God bless you

You guys got the best vids! Thanks

This worked pretty well for my 2005 SL. But I had to remove the coolant overflow tank and the mounting bracket for the relay box, because the bottom bolt wouldn't clear the relay box mount. It was a bit of a pain, but gave me lots more room, too. Not sure what was different about mine, but there was no way that it was coming out without moving that bracket. Other than that, great instructions! Thanks.

This was a great video. Thank you very much

I've replaced several parts on my vehicle using the instructions of the 1A Auto Parts videos. Thank you so much guys for creating and uploading these videos.

Good job! I like a FF video trick -- thanks you!!

Is it the same process for the v6

A huge help. Thank you!

Very helpful video ..Ty

Thanks so much video was extremely helpful

Thanks for the help! That bottom bolt was a bear but other than that, everything went smooth with your awesome walkthrough.

Thanks, y'all saved me ( again) haha

awesome video thank you

thumbs up for 1A auto ..

One of the best concise videos, well done

How do u take off the little clip that holds the wire from the alternator to the sensor on the a/c clutch without breaking it?

Thanks for the video! I just did my 2004 Altima. The only modification is that I had to unscrew the fuse box mounting bracket to get enough clearance to get the bolt out. I didn't have to remove the whole thing, just slide it over a little.

Excelent video, ty master from Guadalajara Mexico

do the same steps apply for a 2002 2.5 s

how long should the 14mm wrench be estimated?

Can the serpentine belt be replaced at this time from the top of the engine bay?

Video was very helpful

Great video tutorial.

Does the engine cover need to go back on or can it be left off?

Thank you.

What was the 5mm bit allen used for? I keep missing it in the video. Thanks!

Nice edit too. Sweet video

are the alternators from 2002 to 2006 the same?

Torque spec for 14mm bolts?

ohhh and thank you very helpfull

Thanks

This was a great video! My son watched this video in order to learn how to give the belt slack via the belt tensioner. Thank you!

Thanks man

Antbodys car turn on but not run when they stepped on the gas?? My car switches from P to D im hoping its the Alternator because it was making a weird noise

I tried replacing my alternator but the second screw the one on the side you said to loosen it up so I could pull the screw out didn’t work. I had to remove the screws from the bottom and removed the whole bracket instead of just screw on the side fuses box. Thanks you for the video you posted on KZfaq.

The bottom alternator bolt is just spinning when I try to take It out. how can I make it stop spinning, that's the only thing holding me back from removing the alternator

How do you make the ratchet go so fast? LOL Nice video

I snapped the lower bolt on the alternator. What's the correct size for a replacement? Thanks!

You guys need to make a video for doing this on the 3.5 V6 models, because it's more involved (have to remove the radiator). Not impossible though..

I want to know if I can use the same alternator for Nissan Altima and Murano

Can u plz make a video changing the belt much appreciated

Hi there does it work on nissan presage 2.5 2004?

Can’t seem to get the 14mm screws loose at all !

I would like to mention that on my 2006 Altima , I also had to remove the fuse box bracket in order to get that lower alternator bolt out. FYI !!

Though is the the same procedure for a 2006 Sentra? Everything's pretty much going to look the same?

i stuck in the higway with bad alternator right now with the same.2003 altima car

Is this the same for 2009 Altima? I'm hoping it's easy for me to replace for a female.

Will this be the same on 3.5 v6

Does your new alternator come with new nuts and bolts??? Just in case????

At least the Nissan engineers were smart enough to mount the alternator front and topside for easy access. The stupid Kia engineers mounted it rear and bottom, making it very difficult to remove and replace. It picks up a lot of dust and road grime and fails prematurely.

will this be the same for 2013?

Help. I have replaced my alternator and battery but my battery keeps dyeing

I followed fuse box on 2006 the metal part I had to put 🔨 down.😅

Why won’t the bottom bolt come out? Not even with my impact is loosing it

Is a2012 the same.??? Nissan Altima???

I just did this and when I went to put the negative terminal back it sparked and a fused popped on the positive terminal?!?!

Thank You!

It's a bit more difficult to do in the sentra, spaces are tighter.

Don't forget to take ur battery off or u could risk shorting out something

That same car and that same job will take a lot longer if you have the V6 trim

Never use a pry bar to remove a bolt. Instead move the fuse block out of the way it just lifts up once the tabs are released. The bracket is actually what blocks the bolt removal. So loosen one bolt and remove the other. Now you can pivot the bracket out of the way and the bolt is easily removed. This way you won't damage the threads of the bolt with a pry bar or bend the bracket making installing the fuse block difficult.

hex bolts won't come out of engine cover. one of them is starting to strip what the hell do I do ?

my alternator is way gone. I will be replacing it soon. Hopefully this will save me around $300 in labor.

02 Nissan Altima alt. not like this. It sit to low with ac holes over it and cooling holes over it check my.y channel out as we fix this 2002 Nissan Altima se 3.5l..

Easier to put top bolt in few threads then dangle bottom until bolt slips in. Much easier

Thanks for this video! Really helped out a lot. :-)

how much the alternator cost by u

What are the torque specs?
