Maintenance and Care

Owner Maintenance

Form No. 8S15-EA-03G

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 FULL and LOW 
marks on the coolant reservoir when the 
engine is cool.

If it’s at or near LOW, add enough coolant 
to the coolant reservoir to provide 
freezing and corrosion protection and to 
bring the level to FULL.

Do not overfill.

If new coolant is required frequently, 
consult an Authorized Mazda Dealer.

Changing Coolant

Change coolant according to Scheduled 
Maintenance (page 8-3).

For mixture percentage:

Radiator coolant will damage paint.
Rinse it off quickly.

CAUTION

•

Use only soft (demineralized) water 
in the coolant mixture. Water that 
contains minerals will cut down on 
the coolant’s effectiveness.

•

Don’t add only water. Always add a 
proper coolant mixture.

•

The engine has aluminum parts and 
must be protected by an ethylene-
glycol-based coolant to prevent 
corrosion and freezing.

•

DO NOT USE alcohol or methanol 
antifreeze. DO NOT MIX alcohol 
or methanol with the coolant. This 
could damage the cooling system.

•

Don’t use a solution that contains 
more than 60 % antifreeze.
This would reduce effectiveness.
