If Trouble Arises
Overheating
Overheating
If the high engine coolant temperature
warning light illuminates, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING
Pull over to a safe location, then
switch the ignition off 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 either 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.
Open the hood ONLY after steam is no
longer escaping from the engine: Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the high engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine compartment.

If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the hood and start the engine.

If neither coolant nor steam is
escaping:
Open the hood and idle the engine until
it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an Authorized Mazda
Dealer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant level.
If it is low , look for coolant leaks from
the radiator and hoses.
