    Does a coolant drain and fill (unscrew drain plug, drain, screw in drain plug, fill up radiator) introduce a bunch of air to the system? If so, how do I go about getting rid of the air in the cooling system?

    I've put about 750 miles on my 2016 i Touring. Everything is great, except now that it's getting warmer outside, I'm starting to smell antifreeze when driving. I don't smell it in the engine bay even after a long drive; it's just in the passenger compartment. That tends to mean a leaking heater...

    They say every 30k miles you should do a coolant flush but is it necessary and what will happen if I don't do it?

    Can we do the TB coolant bypass on our cars? I noticed my tb doesn't get as hot as my 2006 Mazda 3, so I wonder if the tb is heated. Even after lots of driving, it's luke warm at best, but then again it's cold outside.

    I just got a 2004 Mazda 3 hatchback and noticed that there is a very small coolant leak coming from the bottom drivers side corner of the radiator. Does anyone know what this could be?

    I just bought a used 14 3s grand touring w tech package after my 12 3i touring HB skyactiv manual was totaled in a wreck. The new used car has been in an accident where it struck an animal. I know the hood a headlight, the bumper, and radiator was replace with a few bolt on brackets. No frame...

    My wife's 2010 five door grocery getter is four and a half years old with 15,000 on the Odo. Mazda says swap the coolant at 60,000 or four years. Is a coolant swap really necessary considering the low mileage?

    Just checked my coolant reservoir and its almost in the low level. Can i just top it off with any brand of coolant?

    I have a leak that I believe is coming from the coolant outlet housing. I have googled and can find no info on how to replace it. Has anybody got any info on this ? If so it is greatly appreciated.

    After a crazy day today figuring out how my coil pack is broken, mail-man brighten up my day a bit with car parts at least haha. Here is JBR's throttle body coolant bypass & thermal gasket kit (there's more parts to this pic but you get the idea: It's a super simple mod to do the coolant...

    Anyone run purple ice or dominator coolant boost? Had any issues or any difficulty? And are the benefits noticeable

    Did Corksport discontinue the Coolant Tank?

    I'M SO HAPPY RIGHT NOW! LOVE CORKSPORT! So black friday I ordered a PMM and I read the instructions, and it said to to remove the coolant reservoir tank. I remembered on msf.org they had a prototype they were working and waiting to release to the public and a bell just rung in my head. So on...

    Okay everyone, my car is headed to about 4 years old in October/November and only have 17.7kish miles. I'm driving my car up to VA and it will be finally be with me staying up there. Is it necessary to change my coolant for the different weather conditions? If so what kind of mix would I be...

    Anyone ever replace the stock coolant with a waterless coolant such as Evans ? Do they make a waterless coolant for our new skyactiv 3's?

    My 2010 Mazda3 heater control dial has never worked. The heat is HOT only not going down at all when you turn the dial down. Dealer (which was closer to my home) took dash out and replaced heater blender box doors which did nothing. Car has strong smell of coolant after this which it never had...

    Was wondering if there are any(i haven't found one yet) Kits for the coolant hoses in our cars, 10-11s. Or is there a good place to buy my own silicon hoses to replace some of the OEM ones? I would like to do this for 2 reasons, the overall look, and longevity vs OEM rubber hoses. I guess I...

    I'VE SEARCHED!(but my Search-Fu is weak.) I've been to Kragen, Vatozone, and Napa. They all looked at me weird when I said "FL22 coolant." I don't wanna drive to the dealership for a gallon or so. I'm gonna try Vacavalley Auto Part tomorrow. Any suggestions?

    Hi fortunate Mazdaspeed owners. I have HB 2.5. On "our cars" there is no coolant temperature gauge. I believe you do have one. Since this feature (lack of thereof, I should say) is really bothering me, I wanted to ask you where is the coolant gauge in the Speed 3 and also if you would be so kind...

    I have just finished going over the "complaints" department and I have to say I had pretty much the same feelings myself. One thing however: Just a couple of weak pointers about the lack of a coolant gauge? I know this car will be driven for the most part by people who just need to put it in D...
