How do you change the coolant in your 2011 Mazda 3?

Answer 1

To change the coolant in a 2011 Mazda 3, start by ensuring the engine is cool, then locate the radiator drain plug at the bottom of the radiator and place a drain pan underneath it. Open the drain plug to allow the old coolant to flow out, and close it once drained. Remove the radiator cap and fill the system with the appropriate type of new coolant mixed with water, then run the engine for a few minutes with the heater on to circulate the new coolant, and check for leaks. Finally, top off the coolant reservoir to the proper level and replace the radiator cap.
