Great videos! I bought a cheap 2004 Mazda 3 hatchback and have ended up replacing the entire rear suspension, patching up a ton of rust and holes under the side panels (por 15 and fiberglass), did the engine mounts, and now need the belt. I have watched a ton of your videos and just wanted to say THANK YOU as you and a few other Mazda 3 owners have given me the confidence to tackle a lot of this work myself instead of heading to a mechanic. I am by no means rich, or well to do, so saving literally thousands of dollars in labor costs trying to fix a "cheap" car that ive now spent more on parts than the car itself has been great. You really break things down and cover it all and give very descriptive instructions. Thanks again for all the great mazda 3 videos!

[@knappe3223]

Hey Ally just wanted to thank you and let you know I just used this video during my turbo upgrade, I decided to change out the belt, and this video helped me alot better than looking up a tech guide.

[@DustyVids411]

I like your service videos. You dont talk a whole lot of rubbish,.. The parts and car your working on are always clean and easy to see in the footage. More often than not I find it easier to look up a video you've uploaded, rather than getting my mazda workshop manual out. Cheers.

[@everythingdiy]

Dustan Gillot That is so nice to hear. I really appreciate the input!

[@jass355]

+everythingdiy she is so sexy

[@MB-rp7yw]

Awesome! now I know what needs to be done for my Mazda6 when it's being serviced. Thank you!

[@colinfrench7588]

Just bought a used Mazda 3 and this is the first repair to do. Excellent video and great suggestion below to sketch the belt pattern before taking it off.

[@robertm7148]

Thank you for the fine video. I just completed replacing my serpentine belt on my 2013 Mazda 5.

[@marcelomjm5582]

I just want to say thank you for all the awesome videos you help me on many of the repairs on my Speed3

[@jcharles1470]

Great Video!!! I Congratulate you!!! It's very amazing to see a girl repairing her car , she looks very smart!!! Greetings from mexico!!!

[@quentinrance8974]

Good vid, simple, not too wordy, and easy to follow. Thanks.

[@IvanDeSagun]

I wish this video was posted 2 months ago!!! this will help a lot of speed owners. Thanks for making this video.

[@everythingdiy]

Ivan De Sagun :( I know! We wanted to do it so badly but our garage and driveway were under construction for 2 months.

[@mikedoe3074]

You made that look easy. Will definitely be attempting this on the weekend. Thanks

[@szczurDB]

I'm fairly good at many kinds of DIY - light building, decorating, electronics, computers, but car repairs is my Achilles' heel. I dread even a thought of popping up the hood! I've spent quite a lot on DPF and other post-warranty repairs recently at Mazda, but, when my belt snapped the other day on my 5 year old Mazda 6, I said: enough is enough - not paying anyone a penny more! Got the belt, watched few videos on YT and started taking the car apart. Got to the bit where I had to put the belt on, but none of the other videos showed exactly how to loosen the tensioner. Tried few things and was even about to unscrew the tensioner. Since the access was very poor and I lacked a proper spanner to do it (lucky there!), I was just about to give up and call a mechanic out, but then I found this video. If I could reach through the net, I could kiss you!!! I was so chuffed that I actually managed to bloody do it! Seems easy now, and a lot of you will say that it really is, but for a guy with a car repairs phobia, this was a big deal! Thank you so much for uploading this! Saved few quid and learnt something new. Thanks again!

[@ALICEMAYSLOVE8888]

You know your such a huge inspiration to all women who should know how to repair and replace all things in our vehicles ❤

[@chrismorrow3526]

Wow! This is an awesome "how to" video! Very well explained and looks great on HD. Saved me lots of grief and money.. You are my Zoom Zoom Heroine! Thanks so much! :-)

[@wmh.783]

Great video - EXACTLY what I needed to get me through changing the Serpentine belt on our 2011 Mazda3 5-door. THANK YOU. For the Tensioner, I used a Gear Wrench Serpentine Belt Tool. Wow, that made ALL the difference! A second pair of hands (from above) really helped too!

[@donmclean1220]

I just did this on my Ford Focus. It is basically the same. I had to replace the tension pulley as it had disintegrated. None of the videos I watched pointed out that the pulley housing has a place to put a wrench to move it, you don't put a wrench on the pulley itself. Otherwise, this was a clear, concise video, well done.

[@supr2nrx]

Lol. Love your videos, just picked up a serpentine belt and headlight wiring assembly for my girlfriends mazdaspeed 3. I'm gunna make her watch this and supervise her as she does it haha

[@mylittlepony4660]

she not tighten the pulley bolt.

[@abenguyen]

Excellent video and great lighting work! I was planning to pay the dealer or a shop to do this for me but you make it look too easy. I may take a look into doing it myself to save money. Thanks!

[@BuscandoSanaDoctrina]

and the men to cook! Jejejej I'm surprised and I'm glad to see a woman fix a car. God bless you

[@boazwasserman4448]

Great tip about twisting the Engine pulley to slip the new belt back on, wouldn't have made it without it ! Thank you!

[@wadood8700]

Such a helpful and clear video thank you!

[@ahmadqouzah7088]

Great job, kindly need video for built tensioner replacement.Thank you so much

[@danielduarte6086]

so great to see this DYI by a woman!! really motivating for women i suppose, well done, great job!

[@slims8753]

Watched your video to see your method of putting on the belt. "Twist the tensioner, lift the belt while twisting the crank". I was hoping to see everything up to that point. C'est la vie! I like your vids...straight and to the point.

[@drd1924]

Impressed, what a brave lady for changing her own serpentine....I bust my knuckles every time lol. You're welcome to come assist in my shop.

[@StevePhillips]

I love to watch you working on cars. You make jobs seem so easy. You should never trust trolley jacks alone. We always use axle stands as well. We are working on old classic Humber Super Snipe series IV (1963) getting harder all the while to find parts for these type cars. What an amazing diagram what a job you have had to do. It is simpler on our car to change fan belt and put new one. How did you get to becoming such good mechanic did you work with your dad? As it is usually men that go for this type work. Thank you for sharing this video

[@Relyt989]

Thank you for making this Video. It's going to really help me out with my 2010 Mazda 3 2.5L. =)

[@carlosperez415]

Gracias por tu aportación desde GUATEMALA

[@c.aparicio591]

Nice way to do very easy this job, good explanation and faster

[@jseahmed2432]

I like your work ,right to the point .

[@RaCeRx2285]

Great vid! My wife has the same exact color MS3, even powdercoated black stockers lol. Thanks to you, she can pretty much do everything to her speed. Definitely cool to see car chicks who don't need any help from us guys lol. Now I just gotta teach her how to work on my Gen Coupe lol jk. Keep up the vids, they are very helpful!

[@Jessica3020]

Thanks for the video. Putting the belt on was the hardest. For me I had to twist the tensioner all the wayyyyyy up and slide the belt back in by hand. No need to turn the crank.

[@jeepney84]

Thanks so much! Awesome video.

[@yahiasidibenali0470]

Very good job thanks for sharing

[@Cincybritt18]

This is awesome! I love that you are showing that women can do these things! Thank you.

[@savydaniel]

Sure, because no one does the work while "impossible to get that on camera". All her, right :)

[@eraticrellik]

@@savydaniel Not impossible when taking it off, but for whatever reason, getting it back on impossible.

[@terrywilliams6820]

ya right

[@finch0seven]

wow so nice to see women working on cars, awesome!

[@seannleeable]

Legend… thanks for the vid👍

[@jhasmencerese5081]

Good work

[@elaxel1469]

amazing! how did you learned to do this things?

[@NightSociety]

Shouldn't you try to run the engine/motor first before putting everything back on just to make sure? Thanks for sharing nice video angle and instruction.

[@johntahan2189]

Hello Ally, great video, love your 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. Pulley looks good. Would you know where to get that washer part without having to change all the pulleys? Many thanks, John

[@MultiSoulcollector]

I have never seen a car with that much mileage Sooooo Clean

[@ceedell]

I always learn something, I'm so behind on newer cars since I mostly work on old stuff in my shop.

[@archie977]

ceedell do u know the pully diagram on a 2004 mazda 3 2.3?

[@andrereed8813]

I was wondering where did you get your torque specifications for your car. I want to get mine. I have so many things to replace on my car and when I watch ypur videos it makes me wanna do it myself. Ypur vidoes are great.

[@adhnaanyusuf8211]

Nice video

[@MartinCharles]

Wow, it's the first video to actually show the tensioner removal part properly.

[@HoLlEyRoSe1]

Hey! Have you ever had to replace the tensioner pulley? Im having to replace the one on my 2013 mazdaspeed 3 and am looking for any hinters on how to easily do it

[@mudassarrajput8753]

Very nice

[@craigzilla100]

Great video! And wow, what a clean looking engine. I have a MS6, and I wish my access panel to the pulley was that simple! 2 of my screws are hidden behind another bigger panel and it also wraps around the axel and contains two more screws on the left side of the wheel well. Pain in the but to remove..

[@Stinow]

Oof. Thanks for the headsup!

[@ramaroopa7353]

Hi have you ever installed Rogerab in coil springs?

[@dudleyfoster8263]

wow----excellent------If I try this, I guess it`ll be my 3rd time doing it, it's a new tech compared to that OLD internal TIMING chain ---- Would this Accidentally alter the TDC in any way ( depending on the car)

[@macfady2181]

Great vid, went looking for one of yours actually, clear, concise, not 10 minutes of talking. Once everything is seated and routed, if you have someone to release tension it's relatively easy to slip the belt over the smooth pulley last.

[@Mexicnsk8r]

Life saver thank you!!!

[@gbsbill]

great lighting work in hard to see places, thank you. How much is too long 128,000 miles too long?

[@bruceb1200]

I watched video in hopes of learning some trick to install the belt after failing for 2 hours to get it on. Finally got it but had to loosen idler pulley up top to get enough slack to pull belt in by rotating crank. Seems like new belt is a bit too short. what a frustrating nightmare belt job. You gave me confidence to keep trying and succeed!. I love you. Think you are an awesome woman I could easily fall in love with. Wish there were more like you..... : - )

[@gustavomelendez3477]

[@adventureswithadrienne]

11.10.2021: girl you are badd! Girl power 🙌🏾

[@nasrahmed6236]

Thanks

[@garretts91]

Only thing I could add is to make sure to make a clear mental note of the belt routing around each accessory and pulley before you remove it. It'll save you the "Wait a minute, which way did it go?" headache when reinstalling. Sometimes a picture in a manual or under the hood doesn't quite make as much sense as a burnt in image of the belt routing.

[@leoperezroadtrips]

are you using nano socket or just the normal 14mm socket? i try using mine but i can’t get it in to tensioner...using wrench really difficult.

[@quocviet9213]

Nice video, clear voice instruction, smart girl☺☺☺ Thanks

[@krayzietrini3277]

Do you add belt dressing or grease afterwards?

[@stevensolis6507]

Where in the car do you put the floor jack? Did you use a rubber pad on the jack?

[@ur_a_buS]

omg that engine bay and wheel well is so clean! I can't do any work under my car without safety glasses that seal around your eyes, so much dirt, sand, gravel falls on my face. Don't live in a place that has harsh winters. Not worth it.

[@helivesonforever]

@ 1:48, UHHH Scotty Kilmer Style!

[@masteroftt26]

I bought the same belt, is it directional? or can be installed either way, thanks

[@StupDepCraft]

Just a question, I've seen on other videos and on Alldata that i have to take out the AC belt, but your AC compressor seems to not be at the same place as mine on my 2012 Mazda 3 2.0L (MZR). Is it because yours is a speed ?

[@geromecabales1361]

Can you have video on how to replace a steering rack assembly of speed 3

[@nhbilly]

FYI, best method IMO based off my 2010 2.5. It's a two person job less than 1 hour if you hook up the belt to everything first then slide the belt over the water pump while the person holds the pulley.

[@leonardorodriguez3363]

When the belt is worn and it is necessary to replace it, is it necessary to change some other piece? Also how do you see a guide pulley in good condition and in poor condition?

[@pacificislander5977]

Awesome , you go girl, 👍🏻

[@akhrot2642]

Dose squeezing belly effects battery charging

[@seanmcmunn88]

That engine was so clean! Did you detail it before you replaced the belt? Excellent how-to videos by the way!

[@everythingdiy]

Sean McMunn Thanks! We wipe the intercooler down from time to time but we didn't do any special for the video. I guess it helps that where I live doesn't see a great deal of drastic weather.

[@zulgenius609]

what is that belt code vs. its length? or what car model is that? year?

[@blessedinpark]

What did you use to turn the adjuser bolt? There is absolutely no room for a socket/rachet between the nut and the brake lines. An open end just slips on the nut. It seems 14mm is too big and 13mm is too small

[@pacificislander5977]

Awsome girl power instructions, u go girl'! 👍🏻😎

[@londonoalex]

So cute and informative. I hope more girls get to see what you prove is possible. Keep up the good work.

[@mrniceguy423]

Will this work on a 2010 Mazda 3 with 2.0L? I noticed your chart said it would work with 2.5L so why would it not work with 2.0L?

[@dmerced257]

Seems Mazdas are pretty high maintenance. This car seems quite new and you have replaced a lot of stuff already. Btw, replacing the belt on those transverse engines can be a royal pain in the behind. Had a 2000 Rodeo with a lengthwise engine and changing that belt was a cinch. Thanks for the info.

[@RJ-fi9zo]

I think those cracks are acceptable, according to my repair manual, I might be wrong though

[@jengtsai1033]

dear DIY girl, you rock, I have a mazda 5 2012 and I showed some of your video to my wife to boost her confidence and also convenience her that car repair is not a male only club.. wish there could be more car maintenance/repair video performed by female. thanks again.

[@geraldbrown1859]

how will I replace the idle pulley while doing the belt... I have a 201r Mazda 5 2.5

[@chriscalifano8953]

Is this the same idea on a 2013 Mazda Cx-5??? If not can you do a video or point me in the right direction. I just turned 117k and wanna get it changed before it goes bad.

[@bryanbrown4494]

Can you do one on a 2013 dodge avenger video

[@TheDickHead115]

What about installing a Belt Tensioner? And knowing the symptoms if its a bad one or so? I mazda 3 makes this rattling type of noise when I am on Drive and it comes when I come to a stop sign/light and when I brake slowly/at idle at theStop. Took it to Mazda Dealer, chargingMe $500 for part and labor (tensioner and belt) can you help please?

[@crusinscamp]

Good video, two comments. Before you install the new belt you might want to check it by holding the old belt next to it, just to make sure it's the right one. They should be the same length, perhaps the new belt will be just a bit shorter. I'd run the engine briefly before reinstalling all those splash guards, just to make sure everything is tracking OK. Again, good video, thanks for uploading.

[@MrMalefetish]

I HAVE A 2007 CADILLAC DTS CAN YOU MAKE A VIDEO OF REPLACING THE SERPENTINE BELT

[@paulmidi9207]

can you inspect the belt without removing it first?

wut about 2004 mazda - do they have a separate ac belt?

[@AliSaeed]

What about first gen mazda 3 2006? Can youshare the part number?

[@racso5628]

I like this car, but why do they make it so difficult to change the serpentine belt? I currently have a 2000 hyundai accent and I can change the belts without having to jack it up and remove the tire. Are most new cars going this way?

[@rowellnaces1432]

What engine is this? Is it the z6 1.6l?
