How do I add coolant to my Mazda 6?

The coolant should be at full in the radiator and between the F and L marks on the coolant reservoir when the engine is cool. If it is at or near L, add enough coolant to the coolant reservoir to provide freezing and corrosion protection and to bring the level to F.

Do you put antifreeze in coolant reservoir?

Once mixed with water, you simply pour antifreeze into the same place as the engine coolant: the expansion tank, or reservoir. It will then filter 'round the engine and mix with your coolant to make sure the liquid does not freeze.

Does the car need to be running when adding antifreeze?

If the engine is cool, or at least not hot, you can remove the radiator cap and add fluid directly to the radiator, even with the engine running. Under normal conditions, the coolant expands when it gets hot and flows into the expansion tank.
