Overheating

If the high engine coolant temperature
warning light turns on, 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 turns on:
 
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.
