You helped me out today, thanks. That bottom passenger side bolt on the fan, and the fan wiring connection was the biggest pain. Anyone who can still get around before changing, buy the tools you need. Long reach socket wrench, breaker bar, and perhaps the long needle nose pliers referenced in video. I had none of these and had to get creative. Would have probably saved me 2 plus hours having these tools, ugh.

Thank you for this video, it, in my opinion, is the best resource I could find for doing this job, with just an internet search. I found getting the two bolts on the bottom of the radiator loose, the most time-consuming part, and on my 2009 I had to do it from under the car. This meant taking off a bunch of plastic bumper clips to get between the bumper and the rock guard to access the two bolts. While I had the rock guard down and I was down there working, I took off the electrical connector for the fan because it was easier to press the clip and pull down, then pressing the clip and pulling up which dislodges it from the clips metal fastener on the fan itself and gets annoying. My alternator wasn't too much wider than the existing forked opening and between a dead blow hammer and c-clamp I squeezed it in and then with then bolt in the hole I wiggled and smacked the alternator till I got it aligned and it went thru completely. I did use my smartphone once to see if the bolt was coming in straight at the other side of the hole under the engine by filming a video with the flash on, worked great thanks to whoever made that suggestion in the comments. Also, I drilled out any bumper clips that were being troublesome and bought a pack of extras, I know to well the time that can be wasted trying to get corroded clips out, cut my time down a lot. I did this job in 6 hours time including taking the time to clean all the parts I removed and the engine bay when I was done, I am not a mechanic but good at taking instructions and turning a wrench.

Thanks so much for posting this. Doing a video is a PITA. Dealer just quoted me $670 for a new alternator. I'll give it my best shot before I cave in to that kind of extortion.

Thanks for "paying it forward." Very helpful information.

This was a big PITA! Thanks for the video everything you said was correct. Although I used a big C clamp to compress the alternator and it did not work. I ended up just using a pry bar to pry the opening where the alternator mounts to the engine in order to gain fraction of mm to get the alternator in. Aligning the holes was really very difficult. I used a cell phone to record a video of the mounting holes to gauge how far off the alignment of the holes were.

great information & valuable tip with the tensioner!! thank you very much.

Great video. Thanks for putting this together. It was very helpful!

Perfect video for 08-09 accord alternator diy. A++

Thanks a lot for this! It really helped! I've just done this on a 2009 Accord EX and the only difference is that I had to remove front bumper in order to be able to get to the bolts at the bottom of the radiator fan and remove the fan completely. The was just no way to get to them from the top and there wasn't room to get the original out with the fan in place. Removing the bumper is easy - 2 self tapping screws in the wheel wells and 7 of the trim clips underneath.

Alternator went out at 128k miles. This method worked on the same exact car. The Autozone alternator was slightly wider on the large bolt and was hard to fit in. Had to use a clamp to make the alternator smaller in order for it to fit. The autozone cable connector didn't really fit into the alternator either but it could be forced in. The compressor cable ties into the alternator and the autozone alternator doesnt have a slot for the cable so I left the cable hanging. Recommend getting the OEM Denso Alternator. The radiator fan connector was quite hard to disconnect. Overall easy job.Thanks for putting this together.

Thank you so much for your "paying it forward" video

Thank you very much. That is a well done video. Lots of information in a very simple way. Highly appreciated.

Jake, Excellent after the fact video and audio. I have a 2011 Accord V6 and after removing the lower shrouds (in frustration) I figured I check the internet. Great tips especially at the end with the vice!!! after looking at the some of the helpful comments, I'm going to take my time with this one.

Giving you a thumbs up and saying great advice on the Chilton's or Haynes manuals. Thanks for the video, helped me out of a pickle.

Now I don't feel so bad. In 2018, I changed my alternator on my 2009 Honda Accord EX-V6. I kept using breaker bar clockwise to move tensioner pulley. Eventually I figured it out. Well, the next day, 30 miles from home, that tensioner pulley assembly broke. The metal had been weakened. $200.00 tow back home, + $800 in labor costs to extract the broken bolt and install new tensioner pulley assembly.

Just changed out mine this morning. Watched this video and took some notes. Less than 3 hour turnaround. I tried doing it without moving the fan because the bolts on the bottom are a pain to get to, but I had to take it out anyway. Great video and info. Saved me a lot of time. Kudos for the socket sizes.

Good vid... thanks for making the time. I removed/replaced my alternator in my 2008 HON_ACCD V6-3.5 after taking off the mounting screws the belt slip right off and the alternator came out without incident. Be Blessed Jacob

So this vid is good one of the best I found but some advice. He doesn’t mention that this tension bolt is for an Automatic 19mm apparently 14mm for a manual. I would also recommend renting a special tension tool from autozone in my area they basically lend it for free with a deposit. Also note that the tension is due to hydraulic fluid so slow constant pressure is key for it to release the tension. Last thing you really have to jack up the passenger side and unbutton the mud flap to get to the bottom fan screws, and the one closer to the center is going to require a wrench 10mm no way I could get a ratchet in there. Good luck! Mines a 2010 Accord V6, not sure if he mentions it but pulling the power steering fluid and coolant tanks up helps with clearance.

There is a bushing on the under side of the alternator that is holding the old one in place. How do you get that out or moved into a position to where you can get the alternator out.

A big thank you, Mr. Lahmann!!! Your Video was a big help.

you're making a difference, thanks

Is it difficult to put the belt back on? I need to change mine. Started to squeak when it’s cold. Thanks!

One thing I would add. Mine is a 2010 Accord Crosstour. The vice didn't work for me, but I found that the fork to hold the bottom of the alternator has a little sleeve that you can push out to give you room to insert it. It tightens down as you tighten the bolt. Oh, and be sure you disconnect the battery before working on it. 😉

Jack thanks for the video. I'm using a 4" bench vice. I'm attempting to make the gap smaller where the bottom of the alternator mounts to the engine block. All I am doing is bending my bench vise. Any suggestions?? Thanks.

Thank you very much for taking your time to put this out here. I really didn't know how I was going to get that thing out.

Great video. I broke my tensioner bolt off also. How did you replace that?

Thank you just been very helpful and may God bless you as well and may God bless the world

Will this work for my 2.4 motor I have a 2009 ex

Thanks sir I am change my car alternator and I am follow you and I change it without mistake thanks for uploading this video

needed to figure out the tentioner thanks

Awesome, thanks a million

Just did this today on my 2008 accord v6. Very straight forward.. Took maybe 2hrs. Just pop out the plastic clips(have backups) and pray your bottom fan bolts arent as rusted as mine were. Had to get one off with gigantic vice grips. After thats out its super easy. As for the big alternator mount not fitting... My new one had the same problem.... Too big by maybe 1/16 of an inch. I just took an angle grinder and made 2 light passes on the silver bushing on the new alternator, on each side. Nothing crazy. Then it slid right in.

I have a small problem. The tensioner bolt on my 09 accord is slightly stripped & I need to change the alternator. Is it possible to use the bolt at the bottom of the tensioner pulley system to release the belt? The bolts look exactly the same. I am hoping someone can say yes to this. My car has dryer up all my fund’s already. I do not have the money to replace that part of the system right now.

Hey Mr.Lahmann I was working on my alternator got on there no problem thanks to you, but when putting the belt back on the breaker bar snap the bolt part of the tensioner into the ratchet. I was going the correct way as you state it in your video, the tensioner would still work I just have nothing to ratchet to. Would you be able to tell me how I can find that part and or how to to replace it, thank you for your video And help

I thought it was too much also until I went out and started. You have to move the fan assembly out of the way to get alternator out. Hardest part is undoing clips under the car to access lower bolts on the fan.

We can't get the fan assembly to pull out. 2011 Honda Crosstour ex. Having a very hard time trying to get the darn alternator out. Even tried dissembling the alternator while in the engine compartment. Good video. But would have helped if you demonstrated fan assembly removal. When I pull up on it after removing the two top screws, it still pulls the entire radiator up and just won't come loose.

Thanks for the help, going to tackle it today.

Great tips,Thanks Jacob.To avoid possible damage to the alternator case .You do not need to compress the alternator in a vise,once the alternator is out ,tap the outer bushing on the alternator mounting bracket. ,this is where the lower alternator bolt goes through the bracket. The lower alternator bolt hole has a sliding bushing ,sleeve in the alternator bracket,.Gently tap the lower bushing toward the passenger wheel and tire about .,you don't need any excessive force,as it easily slides over with light taps [lubricate if needed ] given the alternator space to slide in.Were only talking about .060 or so movement,no need to get crazy.Should take all of 30 seconds.Be gentle !!! Also once the alternator is out,place the new belt in position.Do not use old belt.Make sure battery is not connected when replacing alternator and do clean the terminals and cable ends .You should also clean the battery with hot water,baking soda if its excessively dirty as it can leak voltage across the top.Put voltmeter to negative terminal and top of case,you should not see any voltage on DCV setting,if you do,clean battery,and check for any cracks,etc Hope this helps.

Excellent video...thank you!

So I went to loosen the bolt tensioner, pushing it towards the passenger seat and it snapped off. What is the best way now to get the belt off the alternator?

Great video!! Thanks!

Great video; very helpful. Thanks for posting. I used the video twice as my replacement alternator went bad after about a year.

Thank you for "paying it forward" sir. I'm no mechanic by anyone's imagination but I also didn't have the $$ the shop wanted to replace the alternator on my car car. What I do have is time. The toughest part for me was the fan's electrical connection. It all ended well thanks to your instructions!

Thanks so much for this video. Would not have known to remove the fan shroud until I got there. It has to be removed.

How on earth did you get to the screws at the bottom of the fan motor?! Did you remove the skid plate?

Thank you sir

YOU ARE THE ULTIMATE BLESSING VERY HELPFUL THANK YOU SO MUCH

Thank You, Thank you, Thank you!!!!

Thanks for the post. It was spot on. I didn't take the radiator brackets off initially, thinking it wasn't necessary. I was wrong! I needed every mm of clearance available. BTW, the original alternator mount measured 45.5mm wide. The new one measured 45.75mm. I tried using a C-clamp (no vice available) to squeeze the mount to that dimension. Couldn't do it. I wound up filing the press fit sleeve instead. An inspection mirror helped aligning the mount to the fork on the engine. Thanks again.

Thank you.

trying to find the OEM alternator, can someone send me the link to buy it please

Nothing changed between the 2008 and 2010 model years, correct?

Roughly, how long should this job take?

I have seen 3 versions.... this one, where he is loosening the radiator.... I guess he did, but we never saw. #2 is a dude that removed the fan and shround.... seemed easy enough. And the 1st vid I saw the guy did not remove anything extra. It took some wiggling, but he got the ALT out.

Thank you, made the job a breeze!

I wish you would have shown the process step by step. Or at least shown how you unclipped the electrical Line from the fan

Im gonna get my alternator in two days. Let me kbow your here for any questions that may arise

Thanks

video would be a lot more effective if job was actually done. Removing the bottom fan bolts (hardest part) is glazed over. Need to jack up the car, remove fender clip. The fan electrical connector is also easier to get hwen you're under the car (huge pain regardless).

Step 1: First find and Fix the leak that allowed oil to run into into the alternator causing it fail. Start with the spool valve gaskets , then check the valve cover gaskets.

Should I make a video of me taking my alternator out

Would figure that Honda would put their alternator in an area that's hard to get to. I'm getting the alternator replaced on my 2010 v6 EX-L Accord by a foreign auto mechanic right now

Great video, just did this today on my 2011 Accord V6. Toughest part was the electrical connection on the fan. I bought a set of long pliers and they helped big time for that part.

Would have been better if you would have recorded and explained while actually removing the items. Other than that, helpful video.

a biiiit less jabber jabber

If you have to put your alternator in a vice to make it fit you probably got the wrong part for your car.

Way better videos on here than this one

No on Chilton and Haynes manuals. Factory Honda Service manual or nothing.

The whole trick with these cars is getting the thing up and out of the car, the only part the video does not show.

And u can't just pull it out...smh

Lazy video ... people learn by seeing.

The over explanations......get to the point

too much bla..Bla..bla

Another" What a waste of time video."

Tell us why smashing that alternator with a vice wont hurt it. Seems to me you are telling people to smash the casing which could hurt it.

Instead of explaining just show the right procedure not how the books says. Books are never right

Just gonna throw this out there but, it would really be great if you did your video while you were actually doing the work rather than trying to explain what you did. Some helpful info here but not enough.

thts too much lecture

a biiiit less jabber jabber
