This is a 20 minute job. Tensioner is lower rear pulley. It even has “LIFT” stamped on it. 1. Take off wheel. 2. Remove splash cover in wheel well over Pulley’s 3. Cut off belt or remove it using tensioner 4. Install new belt Hardest part is rerouting new belt, which took me about 5 minutes maybe. It used your diagram to install new belt

You can also loosen the bottom bolt on the idler pulley (top right when looking at the pulley system from the passenger side) , then remove the two top bolts on the idler and let it rotate to the left side of the vehicle. Route your belt through and then use a prybar to push the idler pully back into alignment with the holes. Done.

For my first belt replacement on a 2013 Mazda 5, it took about an hour, to make sure of no mistakes. This is NOT a nice car to replace it on. If you have a second person to help from the top, it's much simpler. The belt is designed that you MUST route everything from the top first, and the only place you can bring the belt completely over is the bottom pully - it has one side cut flush for that purpose. I ended up using my foot to hold the tensioner so I could use two hands to pull on the belt.

Great vlog, definitely needed two hands.✌

Hi I have a question. I got the belt on but it seems like timing could be off. It’s 2012 Mazda 5. How could I fix that?

No idea. Changing this belt woild not affect timing. I'd take to a shop if timing belt is off. Damage to timing belt might screw up engine.

@@sigor2011 reason I ask was because it has that magnetic timing sensor thing on it and if not on the right tooth than your out of time. After replacing belt it’s dying upon idle down and was hard to start.

This video is COMPLETELY WRONG. Ignore everything about it. The tensioner is there, it's directly below the alternator.

You lost my confidence in your knowledge when you said the car has no tensioner, because in your diagram, which goes with my experience, the tensioner is in the lower rear part of the engine compartment, the one with the triangle in the diagram.

Sorry man, all I could find on-line as I'm not competent enough to make my onw. Prior to 2012, this engine had tensioner but was changed to stretch belt after. Good luck with your project.

Anyway, if there is a tensioner, I did miss it and did not see it, would still get belt replaces either way. But ya, I did not see one and when purchasing part, was told it is a stretch belt. Life.......

By the way, do post where the tensioner is located so others can read where jib can be done differently. 2.3L motor had tensioner on top, easy access... not so on 2.5, they must have moved it into a hard to reach spot.

What good is the video showing you how to install a serpentine belt if you don't show him how to do it this video is useless

So your part was under $16 and you did it in under 6 minutes on a video. Yet, mechanic wants $254.80 sigh.

I'm sure at Mazda dealer belt is priced way more and don't trust the video length. Budget 1 hour at home, probably 30 minutes at the shop.

@Allen & Ginter Wow. Majorly painful. I think I would expect to pay max $600 for tires, $75 for synthetic oil change, $150 for belt with install, and $150 for brakes without new rotors. That's under 1k total... where'd the other $1k go? Did she buy racing tires? I would do the oil change, belt, and brakes myself for about $100 and about 2 hours of my time I think.

Because the dealer knows what they're doing ( not all the time ) and have other expenses to cover. Yes they are a bit more expensive that the average mechanic, but still better than this shade tree mechanic that has no clue that the car has a tensioner and doesn't need a special tool for belt installation. And it probably took him couple of hours to install it while it takes an experienced mechanic 30 minutes without special tool. Sometimes you have to pay for the experience, knowledge doesn't come cheap.
