If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to “N” (Neutral).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about ten minutes.
If the warning doesn’t come back on, you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if
the warning stops. But then, if you still have the
warning, TURN OFF THE ENGINE AND GET
EVERYONE OUT OF THE VEHICLE until it cools
down.
You may decide not to lift the hood but to get service
help right away. When you
decide it’s safe to lift the hood, here’s what
you’ll see:

How to Add Coolant to the Radiator
1
"I
1. You can remove the radiator pressure cap when the
cooling system, including
the radiator pressure cap
and upper radiator hose,
is no longer hot. Turn the
pressure cap slowly to the left
until it first stops.
(Don't press down while turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there
is still some pressure left.
I 3. Fill the radiator
with the proper
mix, up

of the filler neck.

4. Then fill the coolant recovery tank to “FULL COLD.”
5. Put the cap back on the coolant recovery tank, but
leave the radiator pressure cap off.
6. Start the engine and
let it run
until you
can feel the upper
radiator hose
getting hot. Watch
out for the engine
fans.
7. By this time the coolant level inside the radiator
filler neck may be lower. If the level
is lower, add
more of the proper mix through the filler neck until
the level reaches the base of the filler neck.

Add coolant mix at the recovery tank, but be careful not
to spill
it.
Radiator Pressure Cap
Your radiator pressure cap is a 15 psi (1 05 kPa)
pressure-type cap and must be tightly installed
to prevent coolant
loss and possible engine
damage from overheating. Be sure the arrows on
the cap line up with the overflow tube on the
radiator filler neck.
Wlien you replace your radiator pressure cap, ap AC@
cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat
is recommended.
