Thank you. My recommendation: Turn the wheel all the way to the right before jacking up the car. That'll give you more working room. For the tensioner, put the closed end of a 17mm wrench on the nut and then hook another larger wrench onto the other end to give leverage I laid under the car to get the water pump belt on/off. Don't try to put the belt onto the guides of the water pump first. Put it in place on the crank pulley then work it onto the outside of the water pump pulley. Then go back and get it back in place on the crank if it slipped out of place. I found it much easier to start the belt onto the top of the water pump pulley. Takes a good amount of force to turn the belt onto the pulley The serpentine I got from above and the front of the car with my right hand pushing the belt tensioner and my left keeping the belt tight on the crank, ac compressor, and alternator. Seems more awkward but i struggled with visibility trying to work from the side of the car with my hands doing the other job. The belt is gonna come all kinked up and all it's gonna want to do is fly off if you give any slack
Thank you for posting this video! We used it to fix my car's belts when they went out as we're driving down the highway. Made it to a parts store and used your very helpful video.
Great Video! Rag trick is great, most people just cut the old one off, but if you want to keep it "just in case" this is the way to go. It also is good for getting the new belt on. For me, I was not able to get any kind of socket onto the tension cast nut due to clearance, but a 17mm wrench from the bottom worked, and I zip tied it to the axle while I did the belt. Hope this helps anybody else with tight clearance!
Alright so, I did this and it all went well, great video. One problem/solution I had to save some pain: On my 2015 mazda3, There was no space for a socket to ease the tensioner like in the video. The only way to do it is with a wrench from below. But also the main belt (with the tensioner) was a huge pain to get on, even with the tensioner eased all the way. So what I had to do was use a very long 17mm closed-end wrench. Tie a rope to it. pull it all the way towards the front of the car with the rope, then step on the rope. Now you can use both hands above the car to work the main belt onto the alternator from above. Of course if you have another person that would work too but I didn't have help.
@@andrewr7585 around $400 Canadian. The Mazda dealership I bought the car from wanted over $500 Canadian. The service manager looked like he was going to take a stroke or a heart attack when I told him how much the other stealership wanted.
Thank you for this. My belts broke while on the road and had to do this myself in the driveway. One thing I would note is I used Dayco belt E030305 (3PKE774) for the water pump and it was a very tight fit. Did not go on as easily as shown on in the video, it was tough to get even a piece of it on the water pump pulley to start the turning/stretching process. The stock belt appears to be 798mm while this is only 774 and the belt you used in the video is 800mm. I would recommend others avoid this belt and get the OEM one or the 800mm you used to make life easier.
Weird cause the Gates belt I got was 3/4 inch smaller than the OEM belt...impossible to get on. OEM slipped on easy. I'd stick with OEM if doing again for sure....quality control seems much better.
Fyi for anyone doing this, try your best to get an oem belt, it runs the engine you dont want to mess with the fit. Also on mazda 2.0l (probably 2.5l too but i dont have that) its recomended to replace the belts every 60k-70k miles at most to ensure the engine stays running good
This was perfect very short and to the point, but we all know how these projects go, the video convinces you it’ll be like playing with Lego’s and it ends up making you want to pull your hair out because of small issues 😅
Update for anyone trying to do this I just did it today, it didn't take me 30 mins LMAOO more like 3.5 hours because of Idk what the frick I was doing but ended up being able to complete the job, I had this annoying screeching sound it was so annyoing I am glad its gone 34 bucks for the belts, 4 bucks for the 21mm because I couldn't find mine. beats a $150 from the dealership. Thanks andrew R
I have a 2012 Mazda 3 sky active grand touring 5 door. The original bill had 138,000 miles on it. This was the perfect video for this car. The only problem I had was installing the serpentine belt since I was doing it by myself. I ended up using zip ties to attach the belt to the crank pulley and then basically everything went fine.
Very good video - beware of the belt size for the water pump belt - it has to be exact or you cannot install it - I had to get dealer belt for exact fit - standard belt was too small.
Yea it could be bad if the water pump belt broke only could keep driving and cause overheat easily. Just changed both belts at 113k miles. The water pump belt looked great the other one had cracks.
@@markg999 Hopefully the idea is that the serpentine should fail first and then worst case scenario you still have water pump going until the vehicle stalls out without the alternator. With no power steering pump to alert an unaware driver something is wrong, a car with full charge might still go for awhile without alternator
@@andrewr7585 Got the Water and Serpentine Belt Replaced, Serpentine was easy but the Water belt was alittle struggle lol, needed 2 players for the Water pump belt xD
Thanks Questions: 1. Handbrake -what is the position /engaged or not/? 2. Gearbox - what is the position /neutral, parking, gear/ - this might be important when we manually turn the crankshaft
Yea I could see that if water pump just stopped but alternator still turns with other belt ok. I'm at 113k miles belt looks good but better safe than sorry.
Just changing mine for the first time at 168,000 miles. 🤷🏻♂️ They’re cracked and squealing a little. I do all my own maintenance on my vehicles except tires. Not saying wait this long, but if you have to put it off temporarily you’re probably good
No they're different. Serpentine/drive belt runs the alternator, power steering, etc. Timing belt keeps the engine internals in sync with each other. Also, the Mazda 3 has an internal timing chain, not a timing belt.
Good afternoon, I want to congratulate you on your excellent video, a consultation after installing the two belts, how it is synchronized or how many turns must be made to the main pulley so as not to lose the synchronization of the engine, thank you in advance ..
This was exactly what I needed for my son’s 2019 Yaris. The video was concise and very well presented. THANKS…this was truly helpful.😊

Lol just wore your shoes, fuck your shoes. I’ll make sure to replace there belts before or ATLEAST AT their manufacturer recommended intervals

@@andrewjohnson156 Thanks for the information
I had this done at Mazda last month on my 2015 Mazda3. I don’t have the time or patience to do mechanical repairs myself. Been a very reliable car.
What did the dealer charge?
@@andrewr7585 around $400 Canadian. The Mazda dealership I bought the car from wanted over $500 Canadian. The service manager looked like he was going to take a stroke or a heart attack when I told him how much the other stealership wanted.
At what mileage you change it at
@@honestscentz9300 first time was around 35,000 kms. This time was 75,000 kms
I know this is 9months old but you still got bamboozled😂 $400 for 2 belts lol

I used a gates and it’s 813mm. Idk if the sizes vary since my engine is the 2.5?
I think they must be a different size for the different engines. I just checked the OEM part and they’re 817mm
This helped immensely with replacing the belt on my mothers 2014 Mazda 3, thank you very much!

Thanks a lot for the video. As a commentary; use a double star angle wrench for relieving the AC belt tension.

Can I use any wrench to do it? Or do I need a tensioner wrench or something

Awesome. It’s nice they isolate the water pump with a different belt but also looks like a bit of a pain.

Thank you for this.
You're welcome
Thank you so much I was able to do it from the top without removing the wheel but you do need a 2nd person just to relieve the tension (thanks wife)
How did you relieve the tension? I can’t get it to relieve even with the nut loose
Great video, thanks
Rolling the new pump belt on is pretty backyard, observe the 3 pulley bolts for said purpose.
You don't take pulleys off to install//remove belts.
Going to try this out today, got the same belts :0
Good luck!
@@andrewr7585 Got the Water and Serpentine Belt Replaced, Serpentine was easy but the Water belt was alittle struggle lol, needed 2 players for the Water pump belt xD

Questions:
1. Handbrake -what is the position /engaged or not/?
2. Gearbox - what is the position /neutral, parking, gear/ - this might be important when we manually turn the crankshaft
Handbrake on for safety when jacking up vehicle. Gearbox in Park - engine will spin freely from the transmission.
Thank you
Thank you
When is it necessary to replace the tensioner?
Thank you!, gracias al video pude arreglar la faja del carro sin problema😊👏🏼
Great vid, I have a 2015 Mazda 2 DJ Skyactive 1.5 Diesel,.is the same procesure? (very similar engines with the 3 diesel only smaller displacement)
Thank You!
my mazda 3 has 110k miles on it now, i think i better do this quick.
I've read reports of these cars suddenly overheating due to the original belt snapping.
i just hit 110k on my 2014. Both belts showing cracks.
Yea I could see that if water pump just stopped but alternator still turns with other belt ok. I'm at 113k miles belt looks good but better safe than sorry.

Was this video shot in a dark garage
Yes. Unfortunately I didn't have a fully lit studio in my home to make this video.
1 belt or two
2. The second one is only for the air conditioning compressor.
Que modelo son esas correas o numero
Amigo sabes los códigos de las correas para poder comprar,yo tengo un Mazda cx3 y parece que son las mismas
Awesome job. What were the part number for the new belts?
Serpentine Belt: Gates K060378
Water pump belt: Gates K030309SF
Pulley tooth are very sharp, easy cut the belt ,that why need to use tool !
Thank you! Unrelated but what kind of gas mileage are you getting?
About 32 mpg. 50/50 highway vs city
1 sub for you good content.
Is a serpentine the same as a timing belt
No they're different. Serpentine/drive belt runs the alternator, power steering, etc. Timing belt keeps the engine internals in sync with each other. Also, the Mazda 3 has an internal timing chain, not a timing belt.
@andrewr7585 thanks! I called the Mazda dealership and they said Mazda 3's made in in 2009 and newer were all with a timing chain and not a belt?
@@prayunceasingly2029 Sounds right to me
@@andrewr7585 nice, I'm possibly going to buy a used one tomorrow (2009)
Hello Andrew, did you also end up replacing the belt tensioner itself?
No
Good afternoon, I want to congratulate you on your excellent video, a consultation after installing the two belts, how it is synchronized or how many turns must be made to the main pulley so as not to lose the synchronization of the engine, thank you in advance ..
There is no synchronization to worry about. It is not a timing belt.
As the OP said, this has nothing whatever to do with the engine timing
In order to work the tensioner you’re going to need a 12 point socket and not a six
Everyone saying good job but nobody wants to comment how they turned the crank the wrong way?
They turned it clockwise
@@billfrye9234 which way is the good way?
There's no harm in turning the crank backwards a few degrees to help get the belt off...
that water pump belt does not come off that easy at all
Why do they make it look so easy... 🤣🤣When it's a pain in the butt to slide that Serpentine over the alternator.
😢😢😢
