Honda Civic Si Alternator Removal and Replacement DIY (2006-2011 Civic Si K20z3)

[@scottrodriguez712]

Thank you for being so vocal about everything you ran into, also getting great camera angles. Being this job requires many steps in breakdown, it was perfect seeing what's needed in a way that makes it something I can accomplish with confidence.

[@mvxyetti9262]

4 years later and this comes in clutch thank man. I love when YT works!

[@TheGerbsteve]

Glad I could help you out !

[@ulidiaz9157]

You don’t understand how much I appreciate these kinds of videos Gerb, your old videos are Gold to me man I’ve learned so much from you it’s cra7

[@davidhester9716]

This is the best video on replacing the alternator on this model auto. There are others that swapped alternators without removing the upper radiator bracket or cooling fan, but I was not able to achieve removing the alternator. So I will try again with the information you provided here.

[@be.soreal]

Gerb, any problem I've ever had, you got it down and ready to help out! Crazy stuff man! Thanks so much!

[@edgara9316]

Video came in clutch. My alternator died on my way home from the gym yesterday. Kept it simple and quick. Saved me

[@cee_hope]

When it dies what does it do??

[@edgara9316]

@@cee_hope car won't stay on, will run off of the battery till that dies.

[@SamGarza]

Thanks Gerb! I'm going to have to do this tomorrow. Turned on my car and had a whining noise all of a sudden. Mechanics stethoscope placed on alternator helped me narrow it down to the alternator. The alternator also running almost 100 degrees hotter than anything else around it based on my laser temp gun. It should be straight forward after watching your vid. Many thanks!

[@TheGerbsteve]

Let me know how you make out... Hopefully the vid will help ya. Thanks to you for the support

[@SamGarza]

@@TheGerbsteve It's done buddy. Less than 2 hours. Removal of the fan shroud created so much space to work and get the parts in and out. Instead of removing the entire serpentine belt, I just took it off the idler pulley and alternator and moved it slightly to the side. The belt went back on so easy and didn't have to fiddle with trying to get it around the crank and compressor. Once you get to the alternator it's a real easy bolt-off/bolt-on job. Most of the work is removing things to create the space to work.

[@altrrea]

Glad I didn’t looked elsewhere, this is by far the best guide and walkthrough out there. Kudos to you.

[@KhmerUSA999]

I'm feeling so lucky that I have almost the same car like you. Honda Civic SI 2008 Sedan is time to replace a new one now. Thanks so much for doing this show.

[@Mjzzz11]

Thank you so much Gerb productions for uploading these videos for us DIYers !! Saved me a lot of money

[@HugoMatsubara]

wish I had seen this video before... I did the same job months ago, all by myself and it was a pain in the ass to do, but everything worked out... thanks man!

[@TheGerbsteve]

Thank you bro! A/C compressor vid coming next

[@asitwas90]

Appreciate the camera angles on your video. Makes knowing where bolts will actually be much better.

[@kylewagenaar5786]

With all the videos you have my si might be a nice car again some day. You have a video for everything im trying to fix.

[@shanehogarth6373]

Thanks from the UK man, unless I had seen this I would never have believed it could come out this way. I ended up taking the support clip from the AC pipe off as well and that gave me a tiny bit of flex I needed to get the alternator past, it was a tight fit though. Thanks again, huge help.

[@Devinnorrahs]

Weel Gerb here i am again watching another one of your videos to fix my car. As always very informative and helfpul. Hope you are doing well man.

[@NightFlight1973]

Awesome!!! I have an '06 that's still going, but I'm pretty sure the alternator is whining. The EPS triggered while on the highway, and the radio has been flippy since I got the car a couple years ago. I don't drive the car much, but I want to take care of her.

[@forevr_8]

Great video wish I saw earlier, it was sooo tight. I moved the AC line a bit and removed the top pulley and JUST had enough space to get it out w/o removing the rad support but it took many tries

[@LazySpaceRaptor]

Thanks for the video, it's that time for me and I gotta get it fixed myself.

[@chemsrus4914]

Cheers from Alaska. Your video really helped me beyond words and saved me some cash. Super simple, learned a lot about my car in the process. Thank you. Slapped a brand new Denso in my 2009 Civic SI with ease.

[@S0rr0w93]

Big thanks from the UK. Given me the confidence to do this job now on my CTR 👍

[@Loki2Mira]

Great video. I have all this done but for the love of me I can not get the two bottom bolts on my alternator to break loose. The top one came out easy.

[@marismartinsons6694]

If you lower subframe about an inch at the front you can remove it through bottom, i think it is easier that way. Keep those wrenches spinnin

[@TheGerbsteve]

More wrenching to come

[@allenmanning2656]

Man this was so helpful!!!! I did exactly what you did with a few tweaks. Thanks a bunch Gerb!

[@TheGerbsteve]

Np man! I'm glad that i could help you out

[@jerkboxjojo]

Thanks a lot for the great video. You saved me so much time. Thanks for taking time to share on our car!

[@TheGerbsteve]

I made it for all of you who will need it ;)... Thanks for the support homie

[@oGzeR707]

Thanks for the video brother! I’m going to change my sons alternator today. Now I know what tools I need. Appreciate you!

[@TheGerbsteve]

No probs man, glad I can help a bro out 🙏🏻... More diy content coming soon

[@jaredronemus9601]

Thanks for the instructions!

[@cameronbennefield2542]

BTW you can totally get the alternator out to the left of the A/C line, without having to remove the fan. Just use a different hood prop.

[@reynaldobonilla9881]

Thanks brother

[@viddysvideos8336]

Thanks I’m using this video to do ac compressor and ima sub good video man

[@seaney53]

As described in my honda civic 8th generation haynes manual,came here to see if the job was beyond me -and it is! Brilliant video,are most cars this difficult to access the alternator?

[@TheGerbsteve]

I have faith that you can perform his job bro. Believe it or not, civics are one of the easier cars to work on, but I’m sure there’s cars where the alternator is in a crappy place

[@adamholtz1675]

Haha love it. I am going to lubricate my ac and radiator fans while I do this. I forgot if I needed to do the tensioner removal phew...

[@JonTorney]

Appreciate the visuals. I just popped mine out within an hour. Cheers!

[@TheGerbsteve]

Not a problem man. You're quick! Congrats

[@josecaban1118]

I wantes to know if the alternator from the si civic fit in the lx looks the same just wanted to know because the si one is 105amps and the lx is 80amps

[@h22sparkle]

I use my milwalkee electrical ratchet wrench to get on those lower bolts

[@hectorlopez7223]

Amazing, Thanks man!!

[@juelzd7172]

08 si is showing signs of a weak battery, hoping it’s not the alternator but ima test both tomorrow with my multimeter.. this video def helped If I do gotta replace

[@TheGerbsteve]

Hope it helps

[@JuanPerez-yl1jy]

FG2 Problems man. No space at all

[@TheGerbsteve]

The one thing i hate about the 8th gens

[@Willis-de5hx]

What amp is the alternator??

[@paddymccune8512]

Good job , well explained, in clear voice.

[@theghost0602]

That throttle body did you put on

[@TheGerbsteve]

It’s just an oem TB

[@ricardodiaz8719]

what was the sound you heard to replace it? can you include that or send me another video?

[@TheGerbsteve]

It almost sounded like a whining supercharger. Car also had issues with idle and stalling

[@omarortiz4043]

do o have to really take bumper off

[@sickhop831]

Good video !! I have do this soon!

[@SpirituhlOG]

you don't have to go to the dealer to get your radio code you can just look up "honda radio code" on google and it'll be one of the first links my Si doesn't have a sticker on the glovebox just a heads up nice vid!

[@TheGerbsteve]

Thanks man, more to come!

[@Righteous2007]

Never Stop Wrenching

[@AAOSNIPED]

You are a fucking life saver man. I didn’t have to remove the bumper like you did in the video but I got everything like you showed. Thank you!

[@SlimeInnaTaco]

Do ac compressor. This video helped bro

[@Itspossiblekj]

Need to do this, thanks bro

[@JamesSmith-Jtz]

Great video bro, can't wait for the a.c. video, mines been out for way too long

[@TheGerbsteve]

Should be up Sunday morning ;)

[@AndreSRT]

Great DIY video

[@theoneofone2992]

The winding noise can be the ac clutch... They mess up. I have the same noise and ac clutch going weak.

[@johnnylast8536]

Dude u saved me on the clutch so I’m back, got a whiney noise ... told it could be the serpentine belt or alternator. Mechanic put on wd40 on the tensioner and it reduced the noise but still there faintly. Any suggestions ??!

[@TheGerbsteve]

Start small bro, replace the idler tensioner, see if that makes a difference. You could take the alternator off and get it tested to be safe, but just because it reads good for voltage, doesn't mean that it is 100% good. I believe there is bearings inside the alternator that fail. You can stick a long screwdriver against each mechanism and listen for noise. My vote is the AC compressor. Our cars are known for them to fail frequently.

[@kevindumal]

Tank you

[@adamwoltz2228]

replaced everything last week on mine still waiting to do the waterpump when warms up autozones did not fit oreilys got theirs it is oem

[@TheGerbsteve]

Nice! What mileage are you at?

[@danielgardzina6982]

thanks brother

[@jeremyfalkenbach263]

Is this the same for an automatic EX? Just making sure😬

[@TheGerbsteve]

Similar with some steps... Don't know if they're in the same locations or not

[@raymondnoodels7775]

seems pretty similar to my k20a3. thanks. im gonna paint that metal piece under the top cover..

[@TheGerbsteve]

Glad i could help you out bro

[@hmongamericanlife3445]

Hey man, THANKS SO MUCH FOR DONG THIS VIDEO! It looks like a whole lot of pain to do but now with this video, I have an idea of what I need to do. What brand of alternator do you recommend?

[@TheGerbsteve]

You're very welcome. That's exactly why i made it. Denso all the way, even though i cheated out lol

[@highspeedenthusiast6628]

I just smacked the fuck out of that like button✋

[@450-v9w]

Hey, I got some weird problems on my si 07, while driving the radio just turn off one second and restart like I just open the accessories.. so i test my battery with an multimeter to see if the alternator still charging it and it goes to 14.3v with no accessories and 14.1v with all accessories to 13v when the cooling fan goes on. The radio also close while i'm not driving and the cooling fan kicks in. Now, two days ago I can hear kind of whistle sound from the interior of the vehicule when all the engine is hot and i'm not driving it. Can it be the alternator ?

[@TheGerbsteve]

Could be an alternator or ac compressor.

[@samhan7048]

Do you have aftermarket radio? If so recheck wiring. If it’s a whining sound from speakers you have a grounding issue.

[@JoabRivera]

Great Video bro

[@TheGerbsteve]

Neftali Rivera thanks for the support bro 🙏🏼

[@GEO3535]

Thanks for making this video!

[@TheGerbsteve]

Thanks for watching!

[@srserpicol]

Good job dude... I did it exactly the same way...

[@TheGerbsteve]

Thanks bro

[@ileonardR35mk5Supra]

never thought this gonna be a lot of work to do for u to remove that alternator lol

[@bhadz100]

Are you going to replace both ac and alternator?

[@TheGerbsteve]

You will see ;)

[@SniperR8]

much appreciated my dude

[@TheGerbsteve]

Much appreciated support 🙏🏼

[@NightFlight1973]

I saw a notice, but haven't found the video yet. I heard that Midnight died. :( :( RIP midnight.

[@omarortiz4043]

bro did I have a whine sound and burn smell mine did that and it just gave out whole car just off got battery light on b4 it gave completely out and when I would hit gas it would go off but idk

[@TheGerbsteve]

My issue was my ac compressor bro, it caused my car to stall and stuff. Get your alternator & battery tested

[@theoneofone2992]

Ac compressor video!!!!!!

[@TheGerbsteve]

Coming Sunday, stay tuned

[@cristianaquino4431]

[@TheGerbsteve]

Not 100% sure

[@junrowdy]

Where's your front bumper at??

[@TheGerbsteve]

idk, somewhere in the yard lol

[@junrowdy]

Gerb Productions nice lol. Waiting up on the new one?

[@TheGerbsteve]

+Carlos Gomez Haven't decided if I'm going to get a new one yet... found my quick connects, might install those 👍🏼

[@harrytuttle4069]

Thanks! decided this job is beyond me though. :)

[@TheGerbsteve]

You got this! It’s easy, trust me

[@roughywatcher]

saved me $250 thanks!

[@TheGerbsteve]

Glad I could help you out bro!

[@QuantikoOfficial]

if ur just removing the alternator, u can leave the serpentine belt on everything else

[@omarortiz4043]

I was about lower my fa5 tomorrow now I came across this smh

[@adamwoltz2228]

Shoot noise gone after no belt I knew it. Alternator pully did not hear any noise.

[@TheGerbsteve]

Found the problem... You will see ;)

[@adamwoltz2228]

Gerb Productions, I did not get the 2010 Coupe priced too high for condition it was in. Kind of want my 4 door again.

[@TheGerbsteve]

+Adam Woltz I want a four door as well 🤔

[@datstankdough1793]

👍

[@fisherofsouls8634]

i change my alternator on my 09 civic si and the alternator is still not charging the battery any ideas what can it be if so please let me know any help its greatly appreciated it plus I have a alpine nav system and it wont turn on at all

[@TheGerbsteve]

Will the car start? It could be the battery itself.

[@fisherofsouls8634]

The battery its kind of low but i took it to advance and they recharge it and supposedly it good now it doesn’t pass the 11.5 volt tho i took the alternator off today againg ama take it to see if they can check it to see if its good or nah idek wat else to do anymore.

[@TheGerbsteve]

Lmk how you make out... pretty sure you want your whole charging system, alternator and battery to be 14 bolts.

[@angelwalker.]

@@fisherofsouls8634 what ended up being your issue ?

[@everythinghondapro5548]

You don’t need to get the bumper off

[@TheGerbsteve]

I just love to do extra work lol

[@Rawrkee]

Deck, this is a bizzznitch 😭😭😭

[@h22sparkle]

First mistake I saw you make was the plastic clips you need the Lisle clip remover tool to preserve those clips so that you don't have to buy more. You also need a belt removal too hft 20 bucks goes a long way
