    I have a 2014 Mazda 3 with 60,000 miles, but it has a special 100K miles 10 year Total Confidence plan which says "virtually the entire vehicle is covered". Should a leaking drive belt tensioner be covered? The dealer says not.

    Hi guys, I have a 2014 Mazda 3 2.0l and I believe my tensioner is starting to squeak. I gave it a shot of lube and the sound instantly dissipated and then returned.

    Ok, Here's the story. I got the old belt off with no sweat. When I tried to match the new belt with the old belt they appear to be the same size/length. When I tried to install the new one I cannot get enough slack in the tensioner pulley to get it on(couldn't slip on to the crank pulley). So, I...

    Does this happen to your Skyactiv units? It seems its a known issue as some of my club mates here in Philippines had this issue. Is there a TSB regarding this? Thanks.

    I am changing the carpet in my Mazda 3 (2012 4 door). I came across the drivers side seatbelt assy and there is a pre tensioner with a big warning on it and an odd connector. The battery is disconnected. Can I unplug the orange connector to get the carpet out? How do I unplug. Will this...

    I'm trying to change the drive belt on my 2.5 L MZR but I can't get the auto belt tensioner to loosen. I looked in the workshop manual and it states to rotate it clockwise.
