Engine Coolant

Inspecting Coolant Level

WARNING:
Do not use a match or live flame in the engine compartment. DO NOT ADD COOLANT WHEN THE ENGINE IS HOT: A hot engine is dangerous. If the engine has been running, parts of the engine compartment can become very hot. You could be burned.

Carefully inspect the engine coolant in the coolant reservoir, but do not open it.

Turn off the ignition switch and


Turn off the ignition switch and make sure the fan is not running before attempting to work near the cooling fan:
Working near the cooling fan when it is running is dangerous. The fan could continue running indefinitely even if the engine has stopped and the engine compartment temperature is high. You could be hit by the fan and seriously injured.


Do not remove the cooling system cap when the engine and radiator are hot:
When the engine and radiator are hot, scalding coolant and steam may shoot out under pressure and cause serious injury.

NOTE:
Changing the coolant should be done by an Authorized Mazda Dealer.

Inspect the antifreeze protection and coolant level in the coolant reservoir at least once a year―at the beginning of the winter season―and before traveling where temperatures may drop below freezing.

Inspect the condition and connections of all cooling system and heater hoses.

Replace any that are swollen or deteriorated.

The coolant should be at full in the radiator and between the MAX or F and MIN or L marks on the coolant reservoir when the engine is cool.

This would reduce effectiveness.

NOTE:
If the “FL22” mark is shown on or near the cooling system cap, use FL22 type engine coolant. If engine coolant other than FL22 type is used, the engine coolant must be replaced earlier than the specified replacement interval indicated in the scheduled maintenance.

If the coolant reservoir is empty or new


If the coolant reservoir is empty or new coolant is required frequently, consult an Authorized Mazda Dealer.
