    Hey Jordan, I really appreciate you taking the time to make and post this video. I have a 2006 Mazda3 just like yours except mine's a 5-door. I've had it since it was new (10yrs last month) and as much as I love it, a lot of maintenance and repairs are a major pain in the ass compared to other cars! Changing the PCV valve and even the cabin air filter each take a few hours when I could do it in 30 minutes on any of my Hondas.
    I had no idea that I needed a new thermostat until I took it in for emissions testing earlier this week. It only has 98k miles on it and has new plugs and fluids but it failed the emissions test. The printout showed that Code P0126 was the reason. The Check Engine Light didn't come on and I wouldn't have had a clue until the light came on if I hadn't caught it in the test. Anyway, I'm planning to change mine on Saturday. If you hadn't posted such a detailed video, I probably would have spent $150-$200 to have my local mechanic do it....YOU ROCK!

    I found a good way to keep the coolant from gushing out when you take out the radiator plug is to not unscrew the reservoir cap until after you remove the radiator plug. Then you can control the outflow of coolant by slowly unscrewing the reservoir cap while you watch from above as the coolant streams out. It's easier to avoid a mess this way.

      I found it's much easier to combine this method with my method of taking a 1ft piece of old watering hose, slide it over the drain hole and then unscrew the reservoir cap, directed the coolant straight into my drain pan no splashing gushing or mess.

    Thanks Jordan! This vid explained everything perfectly and I was able to complete the job in a very short time. Because I was doing the job in my driveway and didn't have the car jacked up, I elected to get the bottom thermostat bolt from above. It's not too hard but you have to guess where the bolt head is to find it.

  • @martyahad6391
    @martyahad6391 5 років тому +2

    Some points to consider re my 2006 Mazda 3 2.3L: I remove the bottom skid plate every time I change engine oil so it is not hard to remove. Use anti seize paste on the 7 bolts and it will be easier to remove. I noticed that the alternator/power steering belt had brown marks on the top. According to Mazda this is a sign that the belt tensioner pulley bearing is on its way out so I would suggest replacing the pulley as you have it out already. I would replace all the coolant hoses when replacing the thermostat if they haven't been replaced in a long time. This is my summer project next year (2019) to replace all hoses, coolant and thermostat. Regarding comments from others on a means to lift the front end, I made a wooden ramp with 2 x 8 timber. You will end up with a ramp 30 inches long by 7 inches high overall. Use shorter pieces that will end up looking like steps going up to overall 7 inches high. Don't forget to install a shorter piece at the very top to stop the car from rolling off the end! Normal steel ramps will not work as the front spoiler will hit the ramp before the front wheels are off the ground. Dec 17, 2018

    @aaronwelch5774 8 років тому +2

    Thanks for the video! I did the repair yesterday, took me four hours but
    I'm a novice. My advice to anyone doing it is to pay very close
    attention when taking off the skid plate underneath. There's two
    interlocking sections of it which also kind of interlock into the
    bumper. Kind of a puzzle putting it back together. Easy to remove but
    reinstalling it especially without a lift was a bitch. Took about an
    hour but should have been easy. Also to anyone attempting this without a
    lift, it can definitely be done but for the 3rd (lower) bolt on the
    thermostat you'll definitely need a socket with a long extension (as
    shown in vid). It's not that hard if you have that.

    Thanks for the awesome video! Super appreciative of your knowledge. Noticed that the coolant I drained was green and the coolant the manual recommends is FL22 which is a blue coolant. Since I am not doing a flush should I stick with the green that's already in there? Also, I am paranoid about air being in the system. Is that something that will bleed itself through the circulation while refilling the coolant with the car running?

    • @gagekemsley7236
      @gagekemsley7236 4 роки тому +1

      I know this was a year ago that you left this comment, but when you start the car with the reservoir cap off, the system will burp all the air out. If you notice your air doesn't blow hot or the car overheats, try jacking the front end up, take off the reservoir cap and give the car some gas. The force will push the excess air out.

    I just took my drain plug out to change my antifreeze and for some reason I can not get my drain plug to screw back in. Do you have any suggestions or thoughts as to why this is not working for me? I have a 2006 Mazda 3 and the drain plug looks just like what you took out. I have tried removing the washer to see if I could get it to screw in because at first I thought maybe I could not compress the washer enough to get to the threads and get it started but it is almost like there are no threads for my drain plug to screw in to. I am confused and frustrated.

      You can also try looking on the rad cap/overflow cap in your engine bay.

      Just bleed it how it's shown. Open the Drain cap at the bottom and let it all run out.
      This is done so that no coolant leaks out as you're removing the hoses or thermostat itself.

      There shouldn't be too much air. By leaving the filler cap open as the car idles it will circulate the coolant and allow any air that cycled through to be released. Just keep an eye on the level and top up as needed.

    • @jordankoch8974
      @jordankoch8974  9 років тому

      Lewis Morra P0126 error Is caused by Low engine coolant level Faulty thermostat Faulty coolant temperature sensor (CTS) CTS electrical wiring or connector problem - open, short, or poor connection
      If your fan is broken you should be noticing higher than optimal engine temperatures which could cause a number of different codes to appear.
      I'd recommend fixing your fan first.

      MayJay202 You grab the screw itself. It has a bushing that holds it from springing free when loose. once you've back it off and it feels like it's just spinning in place (Kind of like a stripped screw would feel) you can use pliers to pull it out.

      Jordan Koch okay, I got that out, drained all the fluid! Thanks for that! Noow... I got the belt off and up out of the way. But I can't get the bolts off the tensioner. The three bolts? I can't get any of them off. One of my sockets actually broke, like one of the sides cracked out. Do u know how I could solve this problem?

    Any reason I couldn't do this without putting my car on jack stands? Trying to avoid buying them.

      You could do it on the ground with a jack (or two), assuming you fit under the car for the few times needed.

    This took me forever because the previous owner of 11 years did tons of damage to the skid plate. It took forever to get it off.

    If I take the timing belt off does it take it off timing? I'm not sure if you could understand my question but if I do that does the timing go off?

      The belt removed in the video is a serpentine belt, and it runs the alternator, Ac compressor etc... Mazda 3's of this year have a timing chain so noting to worry about! Hope this helps.
