Next thing to do

Check that the cooling fan is operating and
stop the engine once the temperature
gauge needle comes down.

If the cooling fan is not operating,
immediately stop the engine.

Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.

If the coolant level in the reserve tank is
low, add coolant until it reaches the

MAX

mark.

If there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.

■

Last thing to do

Once the engine has cooled sufficiently, restart it and check the temperature gauge.
If the temperature gauge needle has gone down, resume driving. If it has not gone
down, contact a dealer for repairs.

How to Handle Overheating

If the coolant is leaking, contact a dealer for repairs.

Use water as an emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.

WARNING

Removing the radiator cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.

Always let the engine and radiator cool
