Power Steering Fluid
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 arrow on the pressure cap lines 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. The power
steering fluid reservoir is located in the
engine compartment next to the engine coolant recovery
tank. In the 3800 V6 (Code
K) engine and the 3800 V6
Supercharged (Code
I) engine, the power steering
fluid reservoir sits low in the engine compartment. See
Engine Compartment Overview on page
5- 12.

When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
couid indicate a problem. Have the system inspected
and repaired. See Engine Compartment Overview
on page
5-12 for reservoir location.
How to Check Power Steering Fluid
Turn the key off , let the engine compartment cool down,
wipe the cap and the top of the reservoir clean, then
unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then remove
the cap again and look at the fluid level on the dipstick.
The level should be at the
C (3100 V6 engine)
or
COLD (3800 V6 and
3800 V6 Supercharged
engines) mark.
If
necessary, add only
enough fluid to bring the
level up to the mark.
3800 V6 or 3800 V6 Supercharged Engine
When the engine compartment is hot, the level should
be at the
H (3100 V6 engine) or HOT (3800 V6 and
3800 V6 Supercharged engines) mark.
If the fluid is at
the ADD mark, you should add fluid.
What to Use
To determine what kind of fluid to use, see Part D:
Recommended Fluids and Lubricants on page 6-15.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.

If a Tire Goes Flat
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
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.
I
Chant_ g a tire can cause an injury. The v icle
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.

Part C: Periodic Maintenance
Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,
each spring and fall).
You should let your dealer’s
service department
or other qualified service center do
these
jobs. Make sure any necessary repairs are
completed at once.
Proper procedures to perform these services may be
found in a service manual. See Service Publications
Ordering lnformation
on page 7- 10.
Steering, Suspension and Front
Drive Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose
or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals
if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams,
holes, loose connections or other conditions which
could cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See Engine Exhaust
on page
2-3 1.
Fuel System Inspection
Inspect the complete fuel system for damage or leaks.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
