  1. Indicator Lights - 2012 Mazda3 S-Tour (2.0L)

    2010-2013 Mazda 3 Engine and Performance
    My red coolant indicator light came on so I added coolant when discovered it was at an extremely low. Driving for 10 minutes (under 35mph) the red coolant light came in again! AND the blue coolant light, and the TCS/DSC indicator light. Car continues driving fine with no smoke/steam or eeird...
  2. Add coolant or flush?

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I recently purchased a 2014 iSV which has a very low coolant level and I would like to make sure the system is in good shape. The previous owner didn't disclose the last time the fluids were checked or what kind of coolant was last used, but it looks to be an emerald green. I'm thinking of just...
  3. Coolant temp

    2010-2013 Mazda 3 Engine and Performance
    Hi guys, is it just me or are some of you also not feeling very comfortable by not seeying engine temps? The only indicator I see is when starting it illuminates blue and disappears when engine is on temp. I looked up coolant temp through Torque app and it's 98 c at idle! Is that even normal? I...

  6. Will orange coolant destroy my 2010 Mazda 3 S?

    2014-2018 Mazda 3 Skyactiv Discussion
    So I went to my manual and found no reference to coolant specification other than amount. I went to Zerex and it looked like the Asian formula was what I needed. But it is pink the existing coolant is green. Is this a matter of the newer orange being better or is it going to eat the insides out...

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Been looking around for what coolant I can use. Looks like I can use a few types that are compatible with the FL22 coolant. Mazda Coolant FL22 Ford Motorcraft Specialty Green Coolant Zerex Asian Coolant (both red/blue?) I was looking on AutoZone and it seems they carry peak asian coolant...
  8. 2010 mazda 3 GT anti-freeze leak from one of the Coolant Reservoir hose

    2010-2013 Mazda 3 & Skyactiv Discussion
    Hi, today I noticed there was anti-freeze leaks on my drive way and I traced the leak to one of the hose I highlighted in red in the pictures. When I wigged the hose from left the right I saw anti-freeze spraying out near the clamp (the hose cracked near the clamp connected to the radiator). I...
  9. Have you changed your FL 22 Coolant?

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    My 15' mazda 3 came with FL 22 coolant which according to the owners manual is supposed to be good for 10 years. Just like the claim that the transmission is supposed to be sealed for life, I find that hard to believe. Have you replaced your FL 22 and if so how long did you run it in the...
  10. throttle body + coolant

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Any one knows other than cold climates the flow of the coolant via the TB is necessary, I just see that is heating the air unnecessarily.... maybe I can delete that with a bypass.. any ideas. Ps. I live in a 32C, country....
  11. Need to replace a coolant hose, can't figure out which one is the right one.

    2014-2018 Mazda 3 Skyactiv How-To Guides
    Finally found were the coolant leak is coming from. It's from one of the lines that runs to the transmission cooler. When you open the hood and look down there, you'll see two of them one that goes out of the trans cooler and one that goes in. I can't see the part number on them and I don't...
  12. Need to find the source of a coolant leak

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hi, my mazda 3 2014 2.0 was in an accident a few years ago. The transmission cooler mount has a slight bent on the outside pipe were the hose attaches to it. This never created any problems for me other than a few drops a week. Recently my coolant leak has gotten way worse but it's not from...
  13. Mazda 3 engine coolant level

    2014-2018 Mazda 3 Skyactiv Discussion
    I was checking the engine coolant level and it's sitting on low. I heard that it is normal when the car is cold. I checked again today after driving and it's still sitting on low. Does it mean I have to top it off? The car is only 7 months' old and I thought it's a sealed system. I read the...

  15. Oil and Coolant consumption before 30000 km maintenance

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hello everybody. Guys, please advise me in two questions: Mazda 3, 2 L, 165 hp. 1. Soon 30000 km maintenance, now the killometrage is 29,500 km. The oil is now slightly less than half on the dipstick between the maximum and the minimum, which means that 600 ml has gone for almost 15,000 km. Is...
  16. Where the heck to find FL22 coolant?

    2004-2009 Mazda3 Discussion
    So my car is running a little low in coolant. It's at about 67k miles, but I live in an area where it gets pretty humid and hot during the summer. I'm gonna check it later to see why the coolant went low, so that's something on the side. I was able to find Mazda's genuine FL22 coolant on Amazon...

    2004-2009 Mazda3 Discussion
    I currently have coolant fluid leaking from a recessed bolt of some sort on the driver side on my cylinder head on my 2008 Mazda 3i 2.0L. I have searched and search but cant seem to find any reference to this "plug". I was thinking it was a freeze plug of sorts but it is threaded with a hex head...
  19. Coolant overflow cap left open upon delivery

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    So Im not impressed, took delivery of my Mazda 3 today, got home and was going over the car, opened up the hood and found the coolant overflow cap not properly secured. Didn't notice any leaked coolant, but definitely not happy about it. Should I be concerned with air in the coolant system now...
