This video saved my bank account, as a college student it was so much easier to do it myself then have a shop do it for $300. I only had to replace the serpentine belt technically but found it easier and cheaper in the long run to replace both as done in the video.

Just a heads up, when changing the AC belt, Mazda's official service manual recommends to NOT rotate the crankshaft pulley counter-clockwise. The reason being to avoid the crankshaft pulley bolt coming loose and the crankshaft pulley shifting position, which results in change of timing, which can cause major issues (interference for example).

Work perfectly thanks!!! Hints : Zip ties go through both sets of belts. I used ties that were 12” in length and were easy to install. Smaller ones I think would be more difficult. Went on without issue. Also jacking the car up made the job so much easier.

Great video - thanks to this, I was able to replace my two belts very easily... something I thought was going to be a difficult job.

Followed your instructions exactly. Easy 20 minute job.

Wow perfect video without meaningless intro. I love it.

Thank you for this video. I saved about $200 just following this exact step

Thank you! Saved me money. Appreciate the information. It was pretty straightforward.

Doing this tomorrow morning 3.25.24 thanks for the descriptive and well filmed video. Doing the clutch next week when It comes in. (Mines a manual) but I got that. Done it 3 times now on this model

Great job, I need to do my son's 3 soon. You deserve to have a hydraulic jack, thanks for posting.

It worked for me. I just have a suggestion: please put the zip tights the place he recommended. Don’t be creative like and go to the left. Your zip tights will also hold the serpentine and will eventually be stuck in there. I had to make some effort to take them out! Second suggestion, don’t use thick zip tights. They will be troublesome! Good luck.

thanks for the info, just did this job on a 2009 Mazda 3, didnt need cable ties, just forced it on as I turned the crank

Your zip tie trick made this super easy. thanks!

Thanks bro! 👍. Worked fine, but I snapped the cheezy tie wraps and tried metal ones instead. Worked mint! Appreciate it. It's been over 150 degrees in CT lately so this helps.

Thanks for the video, going to be replacing a squealing belt in the next couple weeks, so this was very helpful.

Works well thanks for posting, depends on the clearance on the ac guard I didn’t need to loosen mine the belt slid right under 👍

Really ? Good video ! But just 2 things for you and the viewers: Serpentine is ser pen tine, which rhymes with fine [tine]. And that plate under the a/c compressor is not a heat shield, it is to protect the belt from road debris, so the belt does not get cut or other damage. Stay safe.

Thank you so much ! I would have had to wait until the next day for the "special tool " if it wasnt for your awesome video .

This video was useful. But I had to loosen the serpentine belt first. Then place the zip ties and rotated the pulley. If you don’t loosen the serpentine belt, the zip ties will break and this video will be useless. Once you place the a/c belt. Go ahead and just tighten the serpentine belt.

thanks, just replaced after it blew off. iv would off been fucked without vid. the cable ties to the rescue

I loosened the AC compressor bolts slightly and put the stretch belt on by hand, although it required a little back and forth rotating of the crank and a bit of force, I was able to do it all by hand. Torque down bolts back to appropriate torque, they are quite sensitive being all aluminum. They are 18-26Nm. I think removing the compressor bolts completely as was mentioned in another comment wouldn't work. It would end up being very difficult to line up the bolts with the threads due to the belt pulling the compressor in an angle.. Another jack could be used to push the compressor up so the bolts can go in, but it's even more work, and I didn't want to move the AC lines around too much or put pressure on the compressor housing.. I loosened the two AC bolts closest to the belt a little, and the two furthest from the belt more, so the compressor can angle up, then just did what was shown in the video, but turned clockwise, and held the belt onto the pulley with my hand while turning. Some awkward positioning, as you have to press on the belt right at the very top of the pulley at one point, from underneath the car. I removed all plastic covers because I was doing the alternator anyway so that helped.

Great! Thanks for the tip using the zip ties. I didn't want to buy the special tool.

May I just point out that we should rotate the engine the other way, as in clockwise? Never rotate an engine, especially an overhead cam engine, against its natural direction.

Thanks for the tip, very helpful and saved me money! Your the man!

Thx man. Very informative and clear! Props.

I leave the alternator belt loose until I finish putting on the stretch belt. I found it would get in the way of the zip ties. If the belt tensioner pulley has play then I press out the 6203 bearing and press in a new one.

Great job....but you should not rotate an engine in the opposite direction of it's normal rotation....timing chain or timing belt can jump....it is rare to happen...but it happens

The scissor jack you are using is only meant to be used in an emergency and not as a floor jack for repairs. They are only rated for a limited number of jacks in their lifetime. They are called widow-makers for a reason.

Zip ties really helpful. Thanks for the video

Thanks, I hope you will make a video on changing the radiator and condenser on Mazda 3

Don't turn these motors counter clockwise, it can loose the bolt on the harmonic balancer. Instead zip tie the other side of the balancer and rotate the motor clockwise

I didn’t have the tools I needed for the straight stretch belt hi hell it on with one tire And made a quick crank on the motor and it popped right on

I have a 2012 Mazda 3 with Skyactiv (unlike the great video that Oliver posted). I have a separate AC belt as well as the serpentine belt. However, on mine, it appears that the AC belt is BEHIND the serpentine belt. It looks like I can remove and replace just the serpentine belt (it is the one that is cracked and near end of life). For others that have done this, can I just replace the serpentine belt on the Skyactiv model? Thanks in advance for any responses.

Way to go great tip with the zip ties..

great video! Thank you, Oliver!

I need to swap the pulley wonder how much torque wench. I should use on it thanks you do great videos !!

Great video and not your fault, but my tensioner pulley belt is not a regular bolt, it's a torx...don't know how I'm going to make this happen.

Great zip-tie trick. It worked! Thanks!

does it matter or hurt anything depending on which way you are rotating the crankshaft??

That was an awesome video! I'm ready to tackle my mazda3!

according to manual you are not to turn crankshaft pulley counter-clockwise?

Appreiate the video. Curious if anyone has ever mentioned a problem after using the ccw crankshaft pulley rotation and anyone using cw rotation without trouble doing to get belt on

You stated that your belt(s) still looked fine after replacing. How many miles/years on them? I'm trying to 'stretch' the amount of miles I can put on them - I believe most folks either over-maintain their cars or under-maintain them. Very few optimize part usage. My 2013 skyactiv-G with 70K miles still has all four original brake pads in 'good' condition. The latest mechanic 'review' at the dealership stated that it was time to replace them (belts), however. If I don't see any obvious issues (visual inspection), I'm hoping to go another year or 10K miles.

This was a good video till you started turning the engine ccw..... also the torque wrench isn’t a good tool to use.

I have a 2011 mazda 3 5 spd 2.0 when i turn the ac on there unusual strain on the engine when i want to downshift to a lower gear the engine revs up too slow for me to do a successful downshift and same thing when i put it in nuetral and rev it up it revs up slower then if the ac is off coupd it be a ac clutch or the ac compressor itself? Also i dont get that strain when i turn the heat on

Do I need to replace both belts? I just need to replace my serpentine, but you didn’t specify

Hi Oliver. I have to replace my AC compressor belt also on a 2008 Mazda 5 so they are almost the same. I have a question : I am seeing you rotating the crankshaft clockwise at the beginning, before putting the belt and after that I see you rotating counter clockwise. Can you explain a bit that part? Thank you!

my belt broke off while I was driving and my battery ran dead as soon as I made it in the drive way but as soon as I did my traction control my abs and my battery light was on and I felt a jerk in my transfer case and my gear change a little bit could I have messed up my transfer case. Note I haven’t put my belt on yet

Great video! Would this apply to a 2.3 2008 Mazda 3 as well?

Much appreciated.

Hi Oliver, thanks for the video! Just to make sure, is the socket for crankshaft 21 mm? Does it meter in which direction you rotate /spin the crankshaft? Does the car have to be in Neutral? Thank you

Great video Oliver, nice content. I have question for you and maybe you could help with this. I have a Mazda Tribute 2008 4 cyl. I lost the serpentine and noticed that the top pulley was loose, so I removed it and say that the washer behind it was damaged (it's for the power steering pulley) according to a diagram I found online. Would you know where to get that washer part without having to change all the pulleys? Many thanks, John

do you need to yake off the AC belt in order to change the serpentine belt? I just need to do the serpentine i rarely even use AC

Sorry for the noob question here but are there other terms for "Drive Belt"? Is Serpentine belt different from Drive Belt?

Recently did my friends brother alternator and after the belt was very loose and there was slot on the tensioner. any idea what I did wrong ?

Really helpful

Hi there.. i need the AC belt where can i order? Thank

Hows the belt holding up ? I ask because on amazon few people reorting belt splitting

Thanks you saved me

Noticed all the time that was cut out when the zip ties failed 2-3 times, just to make the video seem useful.

You changed the belt on a 2012 in 2017. The belts go bad in 5 years?

So you shouldn't turn the engine counter clockwise (anti clockwise) ever because tension on the timing chain only works clock wise so you can do exact trick but go Clockwise which is how the engine turns naturally.

This is a novice question, but do I need to have both tires off the ground in order to rotate the crankshaft as shown in this video?

Worked great, thank you!

What did you put the jack stand under holding up the car?

What is the top pulley called on the tensioner Side. Is it the tensioner pulley?

Thank you for for your video worked perfectly

I snapped my first belt, it was a little bit off at the clutch. lol

Whats is the part number on the ac belt?

Great video thanks.

Does anyone know where to get a new splash shield? The one he took off

will it be the same for a 2010 mazdaspeed 3?

I got a question when you turned crank clockwise direction ,the transmission suppose to be neutral position?

Thanksbrother ❤

I have not exactly seen how the belt is arranged

All I did for the a.c. belt is loose up a.c compressor got it on their then tighten the bolts back up and that it

Good shit with the wire ties. Saved my ass.

This isnt a skyactive engine is it?

Need help i bought the serpentine belt,51.5 wont fit to big, change it for 50.0 and still wont fit, stll big whats the measurement for a 05 mazda 3 motor 2.0

Thank you

Mazda dealership said $350 for belt replacement. Is that a fair price?

This method didnt work for me i got so pissed off i used a screwdriver to help me guide the belt. Its to time change again gonna give it another shot

Good video

>always break the lugs loose while the tire is on the ground... lol every-time i get a flat on the side of the road I fudge that and have to put the jack back down...

Is this the same as the 2013 Mazda?

is this the same on 2008??

Polo vivo 1.4 AC not working

Is it the same procedure for 2013 model?

you have done this wrong do not turn the engine anti clock wise as the timing chain may move due to wear

Is it bad that I wanna try this on my sisters car haha, I mean it’s just sitting there and the belt is here….

Why would you cut a belt off? What if the replacement was the wrong length? Seen it many times, dont rely on the model number, printed size. Belts are one of the most commonly returned parts due to manufacturing, sizing and packaging errors. Bando is a good OEM though, but I still see 2 out of 5 returned for sizing errors.

2.0L?????????

It hurts to look at it

why didnt you just take compressor bolts out the belt comes of easy lol

Very clever

My Mazda has one belt

👍👍👍👍🍺😎

Which engine?
