A hot engine is dangerous. If the

inspect the engine coolant in the
coolant reservoir, but do not open it.
Pull over to a safe location, then
switch the ignition o ff and make sure
the fan is not running before
attempting to work near the cooling

Working near the cooling fan when it is
running is dangerous. The fan could

the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously

When the engine and radiator are hot,
scalding coolant and steam may shoot

by an Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year

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
