cools, open the
coolant air bleed
valve or valves.
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.

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 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.

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.

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.

5-24 Removing the Spare Tire and Tools
The equipment you'll need
is in the trunk. Pull the
carpeting from the floor of
the trunk. Turn the center
nut on the compact spare
cover counterclockwise to
remove it. Then lift and
remove the cover.
Turn the wing nut
counterclockwise and
remove it. Then lift off the
spacer and remove the spare
tire. See ªCompact Spare
Tireº in the Index for more
information about the
compact spare.
Turn the nut holding the jack and wrench
counterclockwise and remove it. Then remove the jack
and wrench.

The tools you'll be using include the jack (A),
socket (B) and wheel wrench (C).If there is a wheel cover, loosen the 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
wheel cover until it comes off. Be careful; the edge may
be sharp. Don't try to remove the cover with your
bare hands.

To remove a center cap, use the wrench to pry gently at
the notch. Don't use a tool that is narrower than the
wrench to pry at this notch.
If your vehicle has wheel nut caps, remove them using
the wheel wrench.
Removing the Flat Tire and Installing the
Spare Tire
1. Using the wheel wrench, loosen all the wheel nuts.
Don't remove them yet.
2. Turn the jack handle clockwise to raise the jack lift
head a few inches.
