Overheating
If the engine coolant temperature gauge
indicates overheating and the high engine
coolant temperature warning indication is
displayed, 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 o 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 indenitely 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 engine coolant temperature gauge
indicates overheating and the high engine
coolant temperature warning indication is
displayed:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transmission in park (P), a manual
transmission 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.
