Engine Coolant Level Inspection

WARNING: This page is about a different variant/trim than selected.

Oil and Chemical Type

Engine coolant
Type: Recommended engine coolant

WARNING:

If the cooling system cap or the water-cooled charge air cooler reserve tank cap is removed when the engine is hot, steam and boiling water may be injected, causing severe burns or severe injury. Perform the removal of the cooling system cap and water-cooled charge air cooler reserve tank cap when the engine is cool.
Turn off the engine and wait until it is cool. Even then, be very careful when removing the cap. Wrap a thick cloth around it and slowly turn it counter clockwise to the first stop. Step back while the pressure escapes.
When you are sure all the pressure is gone, press down on the cap using the cloth, turn it, and remove it.

NOTE:

If the "FL22" mark is shown on or near the cooling system cap, use Mazda Genuine FL22 engine coolant.

FL22 type engine coolant is shipped as a diluted solution. Use the solution as is when replacing coolant.

Remove the cooling system cap.
Verify that the engine coolant is filled close to the top of the radiator filler neck.
- If the engine coolant is not filled close to the top, replenish the engine coolant after performing the engine coolant leakage inspection. (See ENGINE COOLANT LEAKAGE INSPECTION .)
Verify that the engine coolant level in the coolant reserve tank is between the FULL and LOW marks.
