The radiator pressure cap is located in the front of the
engine compartment on the passenger's side, near the
diagonal cross brace. See ªEngine Compartment
Overviewº in the Index for more information on location.
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 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 pressure left.2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.
CAUTION:
You can be 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.

3. If you have the 3800 V6 engine, remove the
3800 Series II V6 engine cover shield to access the
bleed valve.
A. Clean the area around the engine oil fill tube and
cap before removing. Twist the oil fill tube, with
cap attached, counterclockwise and remove it.
B. Lift the engine cover shield at the front, slide the
catch tab out of the engine bracket and remove
the cover shield.
C. Put the oil fill tube, with cap attached, in the valve
cover oil fill hole until you're ready to replace the
cover shield.

4. After the engine cools,
open the coolant air
bleed valve or valves.

Bleed Valve

5-19
3400 V6 engine: There are two bleed valves. One is
located on the thermostat housing. The other is
located on the thermostat bypass tube.
3800 V6 engine: There is one bleed valve.
It is located on the thermostat housing.5. Fill the radiator with the proper DEX-COOL

coolant mixture, up to the base of the filler neck.
See ªEngine Coolantº in the Index for more
information about the proper coolant mixture.
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.
6. Rinse or wipe any spilled coolant from the engine
and the compartment.
7. If you have the 3800 V6 engine, replace the
3800 Series II V6 engine cover shield.
A. Remove the oil fill tube, with cap attached,
from the valve cover.
B. Insert the catch tab on the cover shield under
the bracket on the engine.
C. Place the hole in the cover shield over the hole
in the valve cover. Install oil fill tube and cap by
twisting clockwise.

8. Then fill the coolant recovery tank to the
COLD mark.
9. Put the cap back on the coolant recovery tank,
but leave the radiator pressure cap off.10. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fans.
11. By this time, the coolant level inside the radiator
filler neck may be lower. If the level is lower, add
more of the proper DEX
-COOL
coolant mixture
through the filler neck until the level reaches the
base of the filler neck.

5-21
12. 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
arrows on the pressure cap line up like this.
13. 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.
If a Tire Goes Flat
It's unusual for a tire to ªblow outº 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 ªblowout,º 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
skid 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.

5-22
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.
CAUTION:
Changing a tire can cause an injury. 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.

5-23 Removing the Spare Tire and Tools
The equipment you'll need
is in the trunk.
Turn the center nut on the compact spare cover
counterclockwise to remove it. Then remove the cover.
Remove the compact spare tire. See ªCompact Spare
Tireº later in this section for more information about the
compact spare.

5-24
Turn the nut holding the jack counterclockwise and
remove it. Then remove the jack and wrench.The tools you'll be using include the jack (A) extension
and protector/guide (B) and wheel wrench (C).
If there is a wheel cover, loosen the plastic nut caps with
the wheel wrench. They won't come off. Then, using the
flat end of the wheel wrench, pry along the edge of the
cover until it comes off.
If your vehicle has wheel nut caps, remove them using
the wheel wrench.

5-25 Removing the Flat Tire and Installing the
Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts.
Don't remove them yet.
CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even
make the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to fit the jack
lift head into the proper location before raising
the vehicle.

5-26
The diagram shows you where you should place
your jack. Use the bolts (A) as a guide when
positioning the jack lift head (C) near the rear edge
of the front wheel opening (B).
For jacking at the vehicle's front location, put jack
lift about 8.5 inches (21.5 cm) from the rear edge of
the front wheel opening in the cutout of the rocker
panel molding.
Put the compact spare tire near you.The diagram shows you where to place your jack.
Use the notch (B) as a guide when positioning the
jack lift head (A) near the front edge of the rear
wheel opening (C).
For jacking at the vehicle's rear location, put the jack
lift head about 4 inches (10 cm) from the front edge
of the rear wheel opening in the cutout of the rocker
panel molding.
Put the compact spare tire near you.
