Radiator Pressure Cap

Your radiator cap is a 15 psi
(105 Wa) pressure-type cap and
must be tightly installed to prevent
coolant loss and possible engine
damage
from overheating. Be su

the overflow tube on the radiato
filler neck.
When you replace your radiator
pressure cap, 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
AC@ thermostat is recommended.
Power Steering Fluid
How To Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the

on
the dipstick.

Downloaded from www.Manualslib.com manuals search engine When to Check:
Check your tires once a month or more.
Don't forget your compact spare tire. It
should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to
check tire pressure. Simply looking
at
the tires will not tell you the pressure,
especially
if you have radial tires-
which may look properly inflated even
if
they're underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.
Tire Inspection and Rotation
To make your tires last longer, have
them inspected and rotated at the
mileages recommended in the
Maintenance Schedule. See the
Index
under Scheduled Maintenance
Services.
Use this rotation pattern.
Mer the tires have been rotated, adjust
the front and rear inflation pressure as
shown on the Tire-Loading Information
label. Make certain that
all wheel nuts
are properly tightened. See the
Index
under Wheel Nut Torque.
I
Rust or dirt on a wheel, or on
the parts to which it is
fastened, can make the wheel nuts
become loose after
a time. The
wheel could come
off and cause an
accident. When you change a
wheel, remove any rust
or dirt from
places where the wheel attaches to
the vehicle. In an emergency, you
can use a cloth
or a paper towel to
do this; but be sure to use a scraper
or wire brush later,
if you need to,
to get all the rust or dirt off. (See
the
Index under Changing a Flat
Tire.)

When It’s Time for New Tires
One way to tell when it’s time for new
tires is to check the treadwear
indicators, which will appear when your
tires have only
2/32 inch (1.6 mm) or less
of tread remaining.
You need a new tire if:
You can see the indicators at three
You can see cord or fabric showing
The tread or sidewall is cracked, cut
places around

through the tire’s rubber.
or snagged deep enough to show cord
or fabric.
The tire has a bump, bulge or split.
The tire has a puncture, cut, or other
damage that can’t be repaired well
because of the size or location of the
damage.
Buying New Tires
To find out what kind and size of tires
you need, look at the Tire-Loading
Information label. The tires installed on
your vehicle when it was new had a Tire
Performance Criteria Specification
(TPC Spec) number on each tire’s
sidewall. When you get new tires, get
ones with that same TPC Spec number.
That way, your vehicle will continue to
have tires that are designed to give
proper endurance, handling, speed
rating, traction, ride and other things
during normal service on your vehicle.
If your tires have an all-season tread
design, the TPC number will be
followed by a
“MS” (for mud and
snow). If
you ever replace your tires with those
not having a TPC Spec number, make sure they are the same size, load range,
speed rating and construction type (bias, bias-belted or radial) as your
original tires.
I CAUTION I
Mixing tires could cause you
to lose control while driving.
If you mix tires of different sizes or
types (radial and bias-belted tires)
,
the vehicle may not handle
properly, and you could have a crash. Be sure to use the same size
and type tires on all wheels. It’s all
right to drive with your compact
spare, though. It was developed for
limited use
on your vehicle.

Glass
Glass should be cleaned often. GM
Glass Cleaner
(GM Part No. 1050427)
or a liquid household glass cleaner will
remove normal tobacco smoke and dust
films.
Don’t use abrasive cleaners on glass,
because they may cause scratches.
Avoid placing decals on the inside rear
window, since they may have to be
scraped off later.
If abrasive cleaners are used on the
inside of the rear window, an electric
defogger element may be damaged. Any
temporary license should not be
attached across the defogger grid.
Cleaning the Outside of the
Windshield and Wiper Blades
If the windshield is not clear after using
the windshield washer, or
if the wiper
blade chatters when running, wax or other material may be on the blade or
windshield.
Clean the outside of the windshield
with GM Windshield Cleaner, Bon-Ami
Powder@
(GM Part No. 1050011). The
windshield is clean
if beads do not form
when you rinse it with water.
Clean the blade by wiping vigorously
with a cloth soaked in
full strength
windshield washer solvent. Then rinse
the blade with water.
Wiper blades should be checked
on a
regular basis and replaced when worn.
Cleaning the Outside of Your
Chevrolet
The paint finish on your vehicle
provides beauty, depth of color, gloss
retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s
finish is to keep it clean by washing it
often with lukewarm or cold water.
Don’t wash your vehicle in the direct
rays of the sun. Don’t use strong soaps
or chemical detergents. Use liquid hand,
dish or car washing (non-detergent) soaps. Don’t use cleaning agents that
contain acid or abrasives. All cleaning
agents should be flushed promptly and
not allowed to dry on the surface, or
they could stain. Dry the finish with a
soft, clean chamois or a 100% cotton
towel
to avoid surface scratches and
water spotting.
High pressure vehicle washes may
cause water
to enter your vehicle.
