Does the OEM coolant in the car (the "FL22") have the 50/50 coolant mix? Service manual lists only 65/35, 55/45, 45/55. Hope someone could clarify :wink2:Review CarCareKiosk/video/2014_mazda_3_touring
Go to #12 video on burping the system.
Also check out Mazda 3 Forum How to drain antifreeze. For link to DYI--You're basically squeezing the upper radiator hose while the engine is running and the heater controls on high to circulate the 50/50 coolant mix I.e. Distilled Water/Anti Freeze.
Ehtylene Glycol antifreeze, non siicate, no alcohol, borate or methanol.Do not use a solution that contains more
than 60% antifreeze.
This would reduce effectiveness
