An electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing
and tools away from
any underhood electric fan.
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 the COLD mark
on the overflow hose in the coolant recovery bottle. To
check the coolant level remove the cap on the coolant
recovery bottle. Make sure to check that the coolant
level is up to the
COLD fill level on the hose attached to
the cap.
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.
Heater and radiator hoses, a i other engine
parts, can
be very hot. Don’t touch them. If you
do, you can be burned.
Don’t run the engine if there is a leak. If you run
the engine,
it could lose all coolant. That could
cause
an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.

If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running.
If the engine
is overheating and the key
is on, both fans should be
running. If they aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
COLD mark, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL
antifreeze at the coolant recovery tank. (See “Engine
Coolant” in the Index for more information.)
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 coolant 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 DEX-COOL antifreeze.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mix.

You can b’e burned if you spill coolant on hot
engine
parts. Coolant contains ethylene glycol
and
it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at the
COLD mark, start your vehicle,
If the overheat warning continues, there’s one more
thing you can try. You can add the proper coolant mix
directly to the radiator, but be sure the cooling system is
cool before you do it.

How to Add Coolant to the Radiator
NOTICE:
Your engine has a specific radiator fill procedure.
Failure to
follow this procedure could cause your
engine to overheat
and be severely damaged.
hose, is no longer hot. Turn the pressure cap slowly
counterclockwise 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 pressureleft.
2. Then keep turning the pressure cap, but now push
down
as you turn it. Remove the pressure cap.
1. You can remove the pressure cap when the cooling

You can be burned if you spill coolant on hot

3. After the engine cools, open the coolant air bleed valve. 3.1L
V6 (VIN Code
M): There are two bleed valves.
One is located on the thermostat housing. The other
is located on the thermostat bypass tube.
3800 V6 (VIN Code
K) & 3800 V6' supercharged
engine (VIN Code
1): There is one bleed valve.
It is located on the thermostat housing.
4. Fill the with the proper mix, up to the base of the
filler neck.
If you see
a stream of coolant coming from an air
bleed valve, close the valve. Otherwise, close the
valves after the radiator
is filled.
5. Rinse or wipe any spilled coolant from the engine
and the compartment.

6. Then fill the coolant recovery tank.
7. Put the cap back on the coolant recovery tank, but
leave the pressure cap
off.
8. Start the engine and let it run until you can feel the
upper radiator
hose getting hot. Watch out for the
engine fans,
9, 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.

If a Tire Goes Flat
10. Then replace the pressure cap. At any time during
this procedure if coolant begins to flow out
of the
filler neck, reinstall the pressure cap. Be sure the
mows
on the pressure cap line up like this.
11. Check the coolant in the recovery tank. The level
in the coolant recovery tank should be at the HOT
mark when the engine is
hot or at the COLD mark
when the engine is cold. It’s unusual for
a tire to “blow out”
while you’re driving,
especially
if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have a “blowout,” here are a few
tips about what to expect and what to do:
If
a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot
off
the accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out
of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
slud and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and
noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a
flat tire safely.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to
a level place. Turn on your hazard
warning flashers,
Changing a tire can cause an Ijury. The vehicle
can slip off the jack and roll over you or other
people.
You and they could be badly injured.
Find
a level place to change your. tire. To help
prevent the vehicle
from moving:
1. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine.
To be even more certain the vehicle won’t move,
you can put blocks at the front and rear of the
tire farthest
away from the one being changed.
That
would be the tire on the other side of the
vehicle,
at the opposite end,
The following steps will tell you how to use the jack and
change
a tire.
