fluid, follow the manufacturer’s
instructions for adding water.

tank and other parts of the
washer system. Also, water
doesn’t clean as well as washer
fluid.
Fill your washer fluid

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.

Problems on the Road
If the coolant inside the coolant recovery
tank
is boiling, don’t do anything else
until it cools down.
The coolant level should be at or above
“FULL.” If it isn’t, you may have a leak
in the radiator hoses, heater hoses,
radiator, water pump or somewhere else
in the cooling system. I NOTICE:
I
Engine damage from running your
engine without coolant isn’t covered
by your warranty.
[f there seems to be no leak, check to see
if the electric engine fan is running.
If the
mgine is overheating, the fan should be
running. If it isn’t, your vehicle needs
service.
How to Add Coolant to the Coolant
Recovery
Tank
[f you haven’t found a problem yet, but
:he coolant level isn’t at or above the
“FULL” mark, add a 50/50 mixture of
:lean water (preferably distilled) and a
xoper antifreeze at
the coolant recovery
:a&. (See “Engine Coolant” in the Index
for more information about the proper
:oolant mix.)

~~ NOTICE:
~~~
In cold weather, water
can freeze and
crack the engine, radiator, heater core
and other parts.
Use the recom-
mended coolant. When
the coolant in the
coolant recovery
tank is at or above the
"FULL" mark.
start your vehicle.
If the overheat warning continues, there's
ope more thing you can try. You can add
the proper coolant mix directly to the
radiator, but be sure the coolink 7 . 4: y. stem
is cool before you
do it.
A CAUTION:
Steam and scalding liquids from a
hot cooling system can blow out and
burn you badly. They
are under pres-
sure, and
if you turn the radiator
pressure cap
- even a little - they can
come out
at high speed. Never turn
the cap when the
cooling system,
including the radiator pressure cap, is
hot. Wait for the cooling system and
radiator pressure
cap to cool if you
ever have to turn the pressure cap.

How to Add Coolant to the Radiator
1. You can remove the radiator pressure
cap when the cooling system,
including the radiator pressure cap an(
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.

2. Then keep turning the pressure cap,
but now push down
as you turn it.
Remove the pressure cap.
3. Fill the radiator with the proper mix,
up to the base of the filler neck.

cap back
on the coolant
recovery tank,
but leave the radiator
pressure cap
off.

Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch out for the engine
fan.
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.

and refill. If you use this mixture. you
don't need to add anything else.
A CAUTION:
Adding only plain water to your
cooling system can
be dangerous.
Plain water, or some other
liquid like
alcohol, can
boil before the proper
coolant mix will. Your vehicle's
cool-
ant warning system is set for the
proper coolant
mix. With plain water
or the wrong mix, your engine could
get too hot but you wouldn't get the
overheat warning. Your engine could
catch fire and you or others could be
burned. Use a 50/50 mix of clean
water and a proper antifreeze.
NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost
wouldn't be covered by your war-
ranty.
Too much water in the mix can
freeze and crack the engine, radiator,
heater core and other parts. Some conditions, such
as air
trapped in
the cooling system, can af't'ect the coolant
level
in the radiator. Check the coolant
level when the engine is cold and follow
the steps under "Adding Coolant" for the
proper way
to add coolant.
If you have to add coolant Inore than four
times
a year. have your dealer check your
cooling system.
NOTICE:
If you use the proper coolant. you
don't have to add extra inhibitors
or
additives which claim to improve thc
system. These can
be harmful.
%-Valve Engine
Adding Coolant
To Check Coolant: When your engine is
cold.
the coolant level should be at
"LOW," or a little higher. When your
engine
is warm. the level should be up to
"FULL." or a little higher.

To Add Coo1ant:If you need to add more
coolant, add the proper mix
qt the coolant
recovery tank. Add
coolant
mix at the recovery tank, but
be careful not to spill it.
NOTICE:
Your radiator cap is a 13 psi (90 kPa)
pressure-type cap and must be tightly
installed to prevent coolant loss and
possible engine damage
from over-
heating.
Be sure the amows on the
cap line up with the overflow tube
on the radiator filler neck.
When you replace
your radiator pressure
zap, an
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
Ace' thermostat is recommended.
