Engine Coolant
The following explains your cooling
system and how to add coolant when it
is low. If you have a problem with
engine overheating,
see the Index under
Engine Overheating.
The proper coolant for your Chevrolet
will:
Give freezing protection down to
Give boiling protection up to 262°F
Protect against rust and corrosion.

should.
What to Use: Use a mixture of one-half
clean water (preferably distilled) and
one-half antifreeze that meets "GM
Specification 1825-M," which won't
damage aluminum parts.
You can also
use a recycled coolant conforming to
GM Specification 1825-M with a
complete coolant flush and refill.
If you
use this mixture, you don't need to add
anything else.
If you have a 2.2L LA engine, your
engine coolant system will have a
coolant recovery
tank. If you have a
3.1L V6 engine, your engine coolant
system will have a coolant surge
tank.
There are important differences between
these two cooling systems. Read this section carefully.

Downloaded from www.Manualslib.com manuals search engine L 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
50150 mix
of clean water and a proper
antifreeze.
Adding Coolant-2,21 L4 Engine
To Check Coolant:
When your engine
is cold, the coolant
level should be at
FULL COLD, or a
little higher. When your engine
is warm,
the level should be up to
mJLL HOT,
or a little higher.
To Add Coolant:
If you need more coolant, add the
proper
mix at the coolant recovery
tank.

Tires
We don’t make tires. Your new vehicle comes with high quality tires made by a
leading tire manufacturer. These tires are warranted by the tire manufacturers and
their warranties are delivered with every
new Chevrolet. If your spare tire is a
different brand than your road tires,
you will have a tire warranty folder from each
of these manufacturers.
I I
CAUTION
Poorly maintained and improperly used tires are dangerous. 1
’ - Overloading your tires can cause overheating as a result of too much
friction. You could have
an air-out and a serious accident. See the Index
under hading Your Vehicle.
Underinflated tires pose the same danger as overloaded tires. The resulting
accident could cause serious injury. Check all tires frequently to maintain
the recommended pressure. Tire pressure should be checked
when your
tires
are cold.

lnflation-lire Pressure
The Tire-Loading Information label
which is
on the rear edge of the driver’s
door shows the correct inflation
pressures for your tires, when they’re
cold. “Cold” means your vehicle has
been sitting for at least three hours or
driven no more than a mile. Don’t
let anyone tell you that
underinflation
or overinflation is
all right. It’s
not. If your tires don’t
have enough
you can get:

Bad fuel economy. ition)
If your tires have too much air
(overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road
hazards.
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.

Downloaded from www.Manualslib.com manuals search engine Tire hspection and Rotation I
Use this rotation pattern.
After 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.
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.
u I I’ -
Rust or dirt on a wheel, or on
; 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 lt’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

The tire has a puncture, cut, or other
damage that can’t be repaired well

of the size or location of the

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.
