Engine Coolant

qInspecting 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

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.

Without turbocharger

With turbocharger

If it's at or near MIN or L, add enough
coolant to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to MAX or F.
