2010 MAZDA MODEL CX-7 engine overheat

Black plate (373,1)
Overheating
If the temperature gauge indicates
overheating, the vehicle loses power, or
you hear a loud knocking or pinging
noise, the engine is probably too hot.
WARNING
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 either cooling
system caps 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 temperature gauge indicates
overheating:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Shift into park (P).3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from under the hood or from
the engine compartment.
If steam is coming from the engine
compartment:
Don't 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's low, look for coolant leaks from
the radiator and hoses.

If you find a leak or other damage, or if
coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer.
If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required (page
8-22).
CAUTION
If the engine continues to overheat or
frequently overheats, have the
cooling system inspected. The engine
could be seriously damaged unless
repairs are made. Consult an
Authorized Mazda Dealer.
