I found it helpful to remove the passenger side tire and panels to allow for easier access to everything. Everything else was great thanks

I used these instructions for my 2.5 GJ 2013 mazda 6. Worked perfectly. Really loosen the under tray. At least 10 to 15 recoveries of 12mm spanner. Also ratchet spanner is a must. 17mm flare nut spanner works well for compressing the unit, quite secure when you get it on. Thanks for the video, extremely helpful. Saved me over 400 dollars from a dealer. Took me about bang on 2 hours with lots of faffing around

Your video was very helpful. Thank you for making and posting it. My daughter's Mazda 3 pulled into the driveway today making this very same noise. I looked in the engine bay while it was idling and the noise was coming right from the tensioner pulley. In fact the bottom of the tensioner piston that pivots on the the adjusting lever was rubbing the tension pulley.

appreciate the video. been driving my 3 for almost a year with that terrible squealing. I think it's time to replace the tensioner before I run out of luck and end up stranded. thanks

Great video Michael , very helpful. I removed the front wheel and lower plastic wheel arch to gain access from the side and this was much easier than just accessing from the top. I replaced the water pump belt while the tensioner was off which was the hardest part of the job, but all up from start to finish only took an hour and 15 minutes. Its worth getting a 12mm ratchet spanner to remove the tensioner as its hard to get a socket in the space. I used a normal ring and open ended spanner but a ratchet spanner would have been easier and quicker.

Just curious, did this by chance fix the common problem with this Mazda 3 where if you turn the steering wheel, the headlights dim? I'm about to replace the belt on my 2013 because I suspected my belt is worn. The more I research it, the more I think it's an un-fixable problem with this model or just a weak alternator. Also, you might want to check your motor mounts. Seems like your engine flexes front to back a little more than it should.

James Davies: I never heard of that issue. Sorry.

@mfarver 4 жыл бұрын

There is a PCM software fix for low alternator output when under load (the usual complaint is the headlights flicker when decelerating.) Ask your Mazda dealer to apply TSB: 01-13-21. They should do this as an emissions warranty item which is covered out to, I think, 8 years (10 in California). 2012-2013 MAZDA3 - HEADLIGHTS FLICKER WHEN BRAKES ARE APPLIED APPLICABLE MODEL(S)/VINS 2012-2013 Mazda3 vehicles (with SKYACTIV-G 2.0L and Halogen Type Headlights)

Hi, thanks for video , the second bolt which is holding the tensioner is broken , it’s part of the engine what can i do?? Will my car work if i replace it with a small belt and don’t use tensioner?

@MikeNSX Жыл бұрын

Oh boy…. I don’t think smaller belt will last without the tensioner. And you need some way to adjust tension regardless if it’s active or passive. They also stretch a little over time to my understanding. I think you may need a good shop to see what then can do. I can’t recall that second location but I suspect it could be tapped and reset. I don’t have the car anymore to check. Good luck, that’s a rough one.

That oil over all that is most likely a leaky head pan gasket , mine did that as well ! The tensioner doesn’t move much at all and would have been easier with a longer box end wrench 🔧 Just sayin

I’ve looked for a skyactiv vid, but can’t find one. Do you know if you have to take this tensioner off to get access to the second bolt for the alternator? No good alternator removal vids for the skyactiv models.

Does the 2012-2013 Mazda sky active has a lot of Ford parts in the engine and transmission thanks

@MikeNSX 3 жыл бұрын

I’m not 100% sure but I believe no. The SkyActiv is a Mazda engine. In years past the Mazda 6 / Ford Fusion had a shared platform and the Ford 2.3 liter was used on 4 cylinder models (I have a 2008 Mazda 6 with that motor). Transmission I don’t have any data on. In summary I believe the 2012 with SkyActiv is entirely Mazda.

Thanks now I would buy a used Mazda I was looking at a 2013 Mazda 3 sky active Manual transmission or automatics I really like Manual transmission are they Reliable and are they as a Honda Civic 2012 which I owns that has 235,005 miles auto transmission

@MikeNSX 3 жыл бұрын

@@honestscentz9300 I can only tell you my experience. This 2012 automatic has about 160k miles. Only repairs was this and a serpentine belt. It’s been flawless beyond that. My 2008 automatic (2.3 Ford motor) is at 145k miles and I’ve done a value cover and cleaned the throttle body. My only complaint is that I have some rust spots and it’s always garaged. We had an 2008 2.5 Mazda 3 automatic that was at 178k. Engine and tranny were fine but suspension needed work eventually. We bought that at 120k miles so I can’t speak to how it was managed prior. IMO, the Mazda’s are a great choice for low budget reliability. When you are north of 150k miles you need to expect something (even on a Honda). Many factors come into play over 150k miles. How someone drives, maintains and garages (or not) all impact. My buddies civic is at 320k miles but he has a 200 mile daily commute. Cars love that. They don’t like a 10mile commute... Good luck.

If the belts look good do you still have to replace them when you change the tensioner? I did this once before and putting the water pump belt back on was the biggest pain in the ass. I'd like to not have to do that again lol.
