Installing a Mazda 3 Stretch Belt (AC Drive Belt) and Serpentine Belt - DIY Mazda 3 Serpentine Belt

The zip tie method did not work for me on the stretch belt - I figured out a different method that is still cheap and easy! 2010 Mazda 3 2.0 liter stretch belt and serpentine belt installation. The un-installation is easy - just cut the belts :)

Zip ties: Jk

Please don't use lubricants on any serpentine or drive belts on your cars. It is most defiantly not the right way to do this. In fact doing so would cause premature failure and defeat the prepose of having a stretch belt by reducing the intended friction. With the cost of the lithium grease spray + tie-straps, you could of easily gotten a $5 belt tool (wedge type) that is readily available. If you are clearly not a professional please put disclaimers on your vids guys. Im a former Ford/Mazda master tech btw.. if that means anything to yall =|

😂😂😂 right. Approve this message as a fellow ford tech and lexus tech.

Thanks for showing the whole process of the stretch belt! I was going to do a 100k mile coolant flush and preventative maintenance water pump replacement. During the planning for the water pump replacement I decided I should change the serpentine belt... But then realized it would require learning how to do a stretch belt. I'm a novice and this looks very intimidating.

[@IsraelDixon]

My Mazda 3 sounds just like this, I think to myself "how hard could this be?!". I watch this and I went "aww mannn, it's a pain in the ass!"

[@EnigmaEngineering]

Lol. You got this Israel!!

[@jonclements5121]

Great walkthrough, if you remove the spark plugs before doing this it makes turning the engine over a ton easier since you're not fighting the compression of the engine to turn it over.

[@EnigmaEngineering]

Good suggestion - and a good excuse to replace the spark plugs at the same time

[@elopez9869]

This just helped me sooooo much. Thank you sir 🙏

[@Jay-jd4ge]

I just unbolted the compressor and put the belt on in an angle. At this point you’ll find yourself fighting to line up the bolts for the compressor. The trick is to line up as best you can and use a jack to jack up the rear of the compressor so it lines up. Feed your bolts in by hand and make sure you don’t cross thread it. Then give it a zap with your gun and voila. A little tricky but it’s way easier

[@brianpschirrer6913]

Is it possible to do the serpentine. Belt without doing the stretch belt, or is the stretch belt in front of the serpentine belt?

[@soldado.Martinez]

De todos los videos que vi sin duda el tuyo es el mejor you videos was the best thanks you so much bro

[@coreyskull2114]

Sabes las medidas de la banda del A/C ? Cual es ?

[@drakevelazquez8728]

Zip ties! Thinking about removing spark plugs. Should knock a lot of that friction back

[@wilmarrojas2899]

Hey mate question did you. use 6pk1305 or the 6pk1300 Cheers man

[@stingosdungeon]

I would use a zip tie rather than a metal clamp, so as not to damage the belt.

[@RideOrangeKTM]

If a/c doesnt work and dont want to bother. could you possibly not install the stretch belt?

[@jamestm86]

what is the benefit of using the hose clamp?

[@daftydirtybird6940]

the diagram also works on a 2012 mazda 3 2.0 i dont know about a 2.3 though

[@bastogne315]

Is it a timing chain or belt dude ?

[@nealhere]

You gave blood for this video. Thanks

[@ShadowlessPhantom]

I don't know about using grease to slip the AC belt onto the pulley

[@joseg6378]

Hi, what number is the key you used to turn the crankshaft

[@sarahobrien3379]

I think he said 21mm

[@ed370zx3]

Clearance Clarance !

[@kookamunga2458]

Why should I replace both belts and not just the worn serpentine belt ?

[@youcantouchgrasstoo]

the stretch belt / ac belt is front of serpentine belt. ie you can't install the serpentine belt without removing the stretch belt.

[@shartattack12]

yeah.... i think i'll pay my mechanic for this one

[@mellamos1376]

I was driving when (what I believe to be) my alternator belt broke & my car won’t turn over I check under the hood and don’t see any of the belts would this be the reason my car won’t turn over ?

[@EnigmaEngineering]

It's a possibility that something is tangled and preventing your motor from turning over. I would try to manually turn your motor over using the crank pulley shown in this video (do it with a wrench). If you can get it to budge without too much effort, look into your battery/ignition. Do you have a Mazda 3?

[@My5780ta]

Yep if the serpentine belt brakes your Mazda 3 won’t start

[@patrickherb4670]

What if you dont beleiv in air conditioning? And just have no stretch belt??

[@hrbacon]

my sons is missing the stretch belt (for now) and it runs fine.

[@fcdelgado4043]

I thought it was bad to turn the crankshaft counterclock wise.

[@ethanbird8519]

It is, most definitely do not do it

[@jonclements5121]

Also, if you pull on ratchets rather than push you greatly decrease the risk of busting a knuckle.

[@EnigmaEngineering]

I just proved this rule at least twice in 8 minutes :)

[@RealRosieRuiz]

Right but in this case you can't because rotating the engine backward may harm your engine.

[@jonclements5121]

@@RealRosieRuiz This is actually a huge myth, there is absolutely no reason why slowly turning an engine in the wrong direction will hurt it, all of the bearings/seals in engines are designed with rotation in mind, not just rotation in a specific direction. Now, if you were trying to actually crank the engine in the wrong direction that's a different story as it would likely drive the oil pump in reverse, causing no oil pressure.

[@NakedArsenal]

@@RealRosieRuiz You can just change the direction of your rachet so you are only pulling. Or you could try to move to different sides. So you can keep rotating the shaft forward.

[@TrippyZippy]

Hold the head of that Rachet with your left hand. else great work!!

[@tommylol5355]

does the same apply with the 2007?

[@spiz54]

It should

[@flyingoverthehills]

I tried and failed at using zip ties to get the stretch belt installed. They just weren't strong enough! Hose clamp trick for the win. This was on a Mazda CX-9.

[@bastogne315]

What da hell is a stretch belt for?

[@MrBowser909]

Rust on a Mazda 3?!?!

[@RupertColon]

You CAN'T TURN IT TO THE LEFT. BECAUSE TIMING BELT. BAD BAD BAD....

[@My5780ta]

Just remove the AC Compressor much easier 10 minute job

[@EnigmaEngineering]

Great suggestion, thanks Carlos!

[@sarahobrien3379]

I have the skyactiv it looks like the stretch belt is around the crank and water pump I plan on changing the 2 belts when I change the water pump can I use the method you are talking about instead of trying to wall the belt on?

[@manuelsantos6077]

Those clams ,comino, from, I dint, geit

[@johnmartell807]

Why are you using a hose clamp what's the benefit to that

[@johnmartell807]

I've been renching for over 30 Years brother and I have no idea what your doing you do because you're doing it but we don't have a clue you really need to stop and think about that thank you anyways

[@Hyngyynj]

Agreed

[@devonkilgour1896]

is the hose clamp to hold the stretch belt in place while turning the crank?
