  2. Auto trans cooler ?'s 2014 3 iTouring Hatch 2.0L

    2014-2018 Mazda 3 Skyactiv Engine and Performance

Parsing past threads, though not approved in the US for towing, elsewhere in the world, Australia eg, towing with the 3 is ok. Evidently...

    I have a 2012 mazda 3 hatch with the 2.5L in it, 5-speed automatic. I live in Texas so its usually pretty hot. I was told to change my transmission fluid now (just hit 50k, the manual says nothing about when to change) and to the change it every 30k miles. I was also told I should get an...
  4. Adding Engine Oil Cooler to 2.0 Liter Skyactive?

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Has anyone looked into adding the Mazda oil cooler delivered on cars going to Mexico? It fits under the oil filter and is plumbed into the cooling system. Searching I found P/N 14-310A housing that supports the filter and the cooler P/N 14-700. Mazda seems to use the same part number for many...
  5. Using the cooler line to drain and fill or..?

    2004-2009 Mazda3 Discussion
    My 2009 Mazda 3s is coming up on 30k miles and I was just wondering what would be the best option for replacing the auto transmission fluid? Being that I drive in manual mode 99.5% of the time and the liquid that I've been testing from the dipstick is light/moderate brown, should I just drain...

  9. Cold Air Intake routed to transmission cooler opening on manual

    2010-2013 Mazda 3 Engine and Performance
    I have a 3 S six speed and have heard the 3's with an auto have an opening to route air to the transmission cooler. Is it possible to route a Cold Air Intake to the opening that would route air to the transmission cooler? I'm thinking that would be a good spot and maintain a stock look.
  10. Does the 2010 speed 3 have a oil cooler?

    2010-13 Mazdaspeed 3 News & Discussion
    I did an oil change on a 2010 Mazda 3 with a 2.5 in it and I noticed it had an oil cooler on the driver side under the headlight. Does anybody know if the 2010 speed 3 has one? Because it isn't located in the same spot as a regular 3 of the same year.
