Mazdaspeed3 Drive Belt and Tensioner Replacement 

For anyone else who has problems with this, here's what I did: First, make sure to remove the nut holding the power steering pipes on in front of the tensioner. That'll give you enough clearance to get a 6 point socket on. With that and a breaker bar, you can relieve tension. If you use a 12 point socket or box end wrench, it'll round that nut over. You probably will still have a hard time getting the new belt over. I ended up taking off the top two nuts on the top front idler, and with tension relieved, pivoting it to the side to get the belt on. Then I pivoted it back up, and put the bolts back in. Make sure to put the power steering pipes back in place, or they can rub against the belt and get sliced. After that, just start it up and check that it all works well!

This is great video for help on the belt. One thing that is tough is that the power steering lines are in your way from the bottom. I think the easiest way to get the belt back on is to leave the water pump loose and slide that on last because it’s the back side of the belt and it’s smooth.

Thanks to your video I will be doing mine instead of paying someone to do it, thanks brother 🤘

Good video, where do you check for torque specs? I cant find torque specs for tensioner and idler pulley for my Mazda 6 2007 2.3 166hp non turbo L3 engine.

Thanks man , got it done

Great video and details

Quick question, Could you just replace the pulley without the whole assembly?

Thank You

Kamal on your Mazda when you increase your engine speed do your pulleys spin the same speed or faster
