Honda Accord 2.4L Drive Belt (Serpentine) Replacement (I4) 2004 (2003-2007 Similar)

In this video I show you how I replace the drive (serpentine) belt on a seventh generation Honda Accord 2.4L (I4) (2003-2007). Many Honda drive belt replacements are very similar to this.
The exact vehicle in this video is a 2004 Honda Accord EX 2.4L four cylinder sedan.

Awesome video. Just replaced my belt this morning. 15 minute job from start to finish. Thanks for all the tips - especially PATIENCE ! Really urge people to get that tensioner tool that you show in the video. It will save you some bruised knuckles. I bought mine for $30 from Princess Auto ( Canada ) or probably Harbour Freight in the U.S. I was experiencing a whine from the engine when warm. Thought it was tensioner pulley - so I replaced that item but sound persisted. Then I thought maybe a bad power steering pump bearing. But before spending money on a new pump - I opted to replace the serpentine belt even though it looked fine. Once I replaced the belt - I inspected the old belt and found that it was delaminating ever so slightly but in multiple places along the belt. Car runs quiet now - just like new.

[@karlvs2616]

You will need a tool to install it also, thanks for the input!

Thanks for this, gave me confidence to have a go. I didn't think I could reach under the car to the crank pulley so took a 1m steel rod, bent the end over in a vice and covered said end with insulation tape to help move things around down there. Amazingly it worked, took about 10 mins.

This video was awesome!!! The button totally disintegrated after I parked it in my garage, so it has been stuck there for 6 months because I didn't know how to get it out of the garage since it was in park. I even called a local mechanic I have used in the past, he's pretty good, but he said he would have to get under the car to release the linkage so we could shift the car!!!!!😳😳😳 Since we were in the must of cold winter, that has not happened. Now since I have watched this video, I'm going to go get the parts I need and do it myself!! Ps, I'm a woman, but I know I can do this!! Thank you for great video!!!

The Achilles heel is the compressor. In the 7th generation Honda, it is worth getting a V-belt.

[@gregorylambert8975]

Thank you for posting this video bro. Was a little frustrating for me but I got it done with your help. It definitely would help to have that specialty tool from Honda to loosen up that tensioner. I tried it with two smaller wrenches connecting them together and that was a real pain in the ass. So I went to harbor freight and bought a longer 14 mm and even that didn't really have quite the length that would enjoy the leverage to make this much simpler. Your comments about the tensioner and the arrows also are very valuable. I noticed that my tensioner arrow is slightly to the left so does that mean that that tensioner is going bad? Because I noticed that I have a slightly rough idle now. Any comment back would be appreciated on that

[@Nycorexti]

Yes, you should go for a new tensioner

Another great video

[@stevechurch2126]

What does your Honda maintenance manual say about changing the tensioner pulley, does it recommend replacing along with the serpentine belt? Thanks for the video, I replaced my 2012 Accord belt after watching.

[@BigDog50001]

The idler pulley (the part that spins) should be replaced if it makes noise or feels gritty when spinning it by hand with belt off (sometimes it will make a loud obnoxious noise when car is running). Typically the entire Auto-Tensioner assembly (not just the pulley) is replaced if the service indicators that I pointed out are outside of the service limits, if the service indicators bounce back and forth too much when the car is running, if the tensioner does not move smoothly back and forth when moving it with a tool or if the service indicator changes position too much from engine off to engine on. The most tell-tale sign of the Auto-Tensioner assembly needing replacement is a chirping belt, especially at start up or revving engine. Thanks for the comment!

[@stevechurch2126]

@@BigDog50001 Excellent feedback, thank you, I am indeed hearing a chirp at start-up, lasts a fraction of a second, I will take a closer look this weekend (using your points) and likely order the tensioner assembly. Maybe you have a tensioner YT so I'll look for that also.

*Read* *my* *comment* if you are about to attempt this DIY. There are critical difficulties missing in this video. I thought i was well prepared after this video but it is missing key points. I'am a DIY and have done several successful repairs and maintenance in the past including full drum brakes but this seemingly easy belt replacement has several traps. It took me 3 hours split over two days to complete it, so i'm letting you know what pitfalls there are : 1) the loan a tool program from auto shops misses the 14 mm socket for Honda (they have 13,15,16,18 mm). Don't use the included crowfoot 14mm, it'll slip and fall off. Also make sure to use a low profile 14 mm socket or you won't be able to clear out the tool when you finish the install. Even if the tool fits when removing the old belt the new belt might set the belt tensioner slightly more against the motor mount and you won't be able to remove the wrench. So make sure your 14 mm socket is low profile enough. 2) The loan tool standard socket push-in attachment sucks (no retainer), use electrical tape to make sure it won't fall down in the car. I lost one 14 mm socket and have not found it. I had to go buy another at home depot which by chance was a few millimeter lower profile. When i finished the job it barely cleared the space against the motor mount and my original 14 mm socket from my toolbox probably wouldn't have. 3) Big helpful trick: I used a super long braker bar handle that i slid down just next to the crank pulley to prevent the new belt to get off it. That is a big help. maybe you can use a narrow broom handle as well. 4) When pushing the belt over the highest pulley with your hand don't think it seems it won't fit. You have to push one ridge at a time then adjust the belt around the other pulley underneath to get a little more slack. Then push again and repeat to get another ridge in. Don't expect it will work by only pushing in one go. Although it did for this guy, it did not for my car. That's about it. If i had known all this before hand it probably would have taken me 20 min. Always be doubful of these DIY where they complete the job in 10 min, it can be luck or they just got over the difficulty without showing them.
