About 4 weeks ago, the passenger seat belt light began going off (chiming/flashing) with no one in the vehicle except myself in the driver's seat. I buckle my...

    Has anyone every replaced their belt tensioner. I have a 2014 sGT and dealer said the tensioner is leaking and needs to be replaced. Quoted 224 plus tax. Trying to decide if its worth it to do myself or have the dealer do it. Thanks.

    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. Anyone know if I can buy the pulley by itself, or take the pulley off and re grease the bearing so not to have to buy the entire...

    There is black soot on my belt tensioner, and at high rpms a noticeable high pitch (not loud) wine occurs. I think the belt tensioner is going. Anyone have to deal with replacing one?

    I purchased my car and the seat belt was fixed (not the correct way) and the mechanic put a resistor on the harness and cut the plug that comes from the harness to the seat belt airbag... this was done before I purchased the car, so now I want to purchase a new seat belt but I dont have the...

    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...

    Howdy all! I'm new to the 3 family and so far I love it. I do a lot of in and out of my 3 without ever getting on a public road and the seatbelt chime gets annoying after a while (don't worry, I'm religious about buckling up when I drive on a public road). Is this possible on these new cars? I...

    Hi Guys, I'm from Singapore and am driving a Mazda 3 2014 1.5 with 6-speed AT. I'm getting this growling noise that seems to come from engine compartment followed by occasional belt squealing noise. - Growling noise (and vibration) happens mostly when accelerating during low rpm/higher gear...

    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. I put a wrench on the pulley bolt and tried rotating in the direct that it says LIFT, and tried pushing it by hand to. The...

    2015 3sGT HB, less than 2K miles... had our first passenger in the back seat and third time in the car the seat belt would not latch. Of all the complex things that could fail, it's hard to believe something that should be so robust would be problematic. Question: can these things get out of...
