floor. Do not apply water from a
high-pressure washer nozzle
directly to the electric connectors.
Failure to observe this precaution
can lead to faulty operation of the
electrical system. If an automatic
car or truck-wash is used with
vehicles having dark or metallic
coating, the painted surfaces can be
damaged by the brushes, lose their
luster or be very noticeably
scratched.
Do not direct a large amount of
water at the air inlet openings. Do
not apply water to the engine
compartment or at electrical
components. Failure to observe this
precaution can lead to a poorly
starting and operating engine and
problems in the electrical system.
Ensure that mirrors and the antenna
are retracted before washing the
vehicle.
If an automatic car or truck-wash
must be used, avoid a
high-temperature, high pressure
type machine. Failure to observe
this precaution can lead to heat
deformation and breakage of plastic
components, or to water leaks intothe cab. When using an automatic
car or truck-wash, ensure that a
distance of at least 0.4 m
(15.75 inches) is maintained
between the nozzle and the vehicle,
and when washing door windows,
that the spray is perpendicular to
the surface of the glass.
Ensure that all detergent is fully
washed and wiped away.
Particularly in the case of strong
alkaline detergents (typically those
for industrial uses), there is a
danger that hairline cracks can
develop in lighting-cluster lenses if
the vehicle is operated without
detergent being fully wiped away.
Always read the detergent
manufacturer's instructions carefully
before use. Airborne dirt that
adheres to plastic front bumpers as
a result of rain, for example, can be
difficult to remove. In such a case,
use a commercially-available
cleaner to clean away the dirt, and
then apply a wax for use with plastic
components.Vehicle Storage
In order to maintain your vehicle's
attractive appearance as long as
possible, special consideration must
be given to its storage location.
If the vehicle is stored or kept for an
extended period of time in any of
the following locations, a chemical
change may occur in the paint work,
resulting in staining, discoloration,
rusting, and corrosion of
components.
.
Locations where a large amount
of oily matter, soot, heavy smoke
or metal powder can adhere to
the vehicle.
. Areas around pharmaceutical
plants and other facilities that
discharge chemical matter.
. Coastal areas
. Locations where a large amount
of dead bugs, bird droppings or
tree sap can adhere to the
vehicle.

Vehicle Care 337
Polishing and Waxing
Periodic polishing and waxing is
recommended to remove built-up
residue and eliminate any
"weathered" appearance.
Your authorized dealer offers
several polishes and cleaners which
have proven value in maintaining
original finish appearance and
durability.
Painted and chrome-plated surfaces
should be waxed once or twice a
month, or whenever water is being
poorly repelled on the surfaces.
Ensure that wax is not applied in
direct sunlight, and that the
temperature of the painted surface
is no more than 40 °C (104 °F).
Always follow the instructions
provided with your wax product.
Do not use wax containing abrasive
material. Failure to observe this
precaution can lead to scratching of
painted surfaces or plastic
components.
The application of wax to rubber
component surfaces can result in
permanent whitening.Wax must not be applied to the
windshield. Failure to observe this
precaution can result in irregular
reflection of light, impairing
your view.
Protecting Exterior Bright Metal
Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Washing with water is all that
is usually needed.
Use special care with aluminum
trim. To avoid damaging protective
trim, never use auto or chrome
polish, steam or caustic soap to
clean aluminum. A coating of wax,
rubbed to a high polish, is
recommended for all bright metal
parts.
Weatherstrip Lubrication
All weatherstrips should be
periodically lubricated (minimum of
every 6 months) with a silicone
grease lubricant. A thin film of
silicone grease lubricant should be
applied using a clean cloth. Silicone
grease application will lengthen
weatherstrip life, help sealing, and
assist in eliminating squeaks.
Windshield Care
Wax must not be applied to the
windshield. A layer of wax can
impair your view in rainy weather
and can also lead to rough
movements of the windshield wiper.
If engine oil or grease comes into
contact with the windshield, staining
or discoloration may result. It must
be immediately cleaned away.
If not fully cleaned by the windshield
wipers, the windshield should be
cleaned using glass cleaner. If your
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.
The windshield wipers on your truck
can be pulled out from the
windshield to provide easier access
for cleaning.
Clean the outside of the windshield
with a non-abrasive cleaner. Your
windshield is clean if beads do not

form when rinsing with water. Clean
the blade by wiping with a cloth
soaked in a solution of one-half
water and one-half methanol
alcohol. Then rinse the blade with
water.
The windshield wiper arms may be
swung out, away from the glass, to
provide easy access for cleaning.
Do not hang on to the roof marker
lights while cleaning the windshield
or damage may occur (resulting in
possible water leakage).
External Diesel Engine
Cleaning
The engine does not need periodic
cleaning, nor is it recommended.
If you insist on cleaning the engine,
clean it only when it is cold, never
when it is warm or hot, and never
when the engine is running.
Spraying or pouring water or other
fluids on your engine when it is
warm or hot, or when it is running,
can cause serious damage to the
engine and its components,
particularly the fuel supply pump.

Vehicle Care 339
Cooling efficiency is compromised
when there is dirt or dust plugging
air passages in the radiator core
and charge air cooler core (diesel).
This can also cause corrosion of
these cores. Wash the radiator core
with tap water every 24 months.
Make sure to turn the engine off and
remove the key from the engine
control switch before cleaning
cores.
The engine, exhaust pipe, and
radiator will be hot immediately after
the vehicle is driven. Be careful
around these parts to prevent burns.
Clean the engine when it is cold.
Do not clean the radiator, charge air
cooler (diesel) and their surrounding
areas using water that is supplied
under high pressure. Doing so may
cause damage.
When cleaning the radiator core (1)
and charge air cooler core (2) , do
not crush or damage the fins (3).
The fins are very fragile so be
careful not to bend them out of
shape. If they become deformed,
their cooling efficiency will be
impaired. Before cleaning, take
steps to ensure that no water will
splash onto the surrounding
electrical components and wires.
If stubborn dirt still remains even
after the radiator core and charge
air cooler core (diesel) have been
cleaned, have the vehicle inspected
and serviced.
Corrosion Protection
Your vehicle has been designed and
built to resist corrosion. Special
materials and protective finishes
were used on most parts of your
vehicle when it was built to help
maintain good appearance,
strength, and reliable operation.
However, some parts which
normally are not visible (such as
those under the vehicle and under
the hood) are such that surface rust
will not affect their reliability. So
corrosion protection is not needed
or used on these parts.
Sheet Metal Damage
If your vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to the parts repaired or
replaced so that corrosion protection
is restored. (Also see "Finish
Damage" which follows.)
Foreign Material Deposits
Calcium chloride and other salts,
ice-melting agents, road oil and tar,
tree sap, bird droppings, chemicals

Chevrolet Low Cab Forward Owner Manual (GMNA-Localizing-U.S.-

340 Vehicle Care
from industrial chimneys and other
foreign matter may damage vehicle
finishes if left on painted surfaces.
Prompt washing may not completely
remove all of these deposits. Other
cleaners may be needed. When
using chemical cleaners, be sure
they are safe for use on painted
surfaces.
Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be
repaired promptly. Bare metal will
corrode quickly and may develop
into major repair expense. Minor
chips and scratches can be repaired
with touch up materials available
from your authorized dealer or other
service outlets. Larger areas of
finish damage can be corrected in
your dealer's body and paint shop.
Underbody Maintenance
Corrosive materials used for ice and
snow removal, and dust control can
collect on the underbody. If these
materials are not removed,
accelerated corrosion (rust) can
occur on underbody parts such asfuel lines, frames, floor pan and
exhaust system even though they
have been provided with corrosion
protection.
At least every spring, flush these
materials from the underbody with
plain water. Take care to clean well
any areas where mud and other
debris can collect. Sediment packed
in closed areas of the frame should
be loosened before being flushed.
If desired, your authorized dealer
can do this for you.
Interior Care
General
Remove dust and dirt from the
interior of the cab using an
automotive cleaner or vacuum
cleaner, and gently wipe surfaces
clean using a cloth wet with warm or
cold water.
{Warning
Water should never be sprayed
directly into the interior of the cab
when cleaning. Failure to observe
this precaution can lead to vehicle
malfunction and possibly to fire if
water should enter the audio
system or other electrical
components located underneath
the floor carpet.
Petroleum ether, gasoline and
other organic solvents should not
be used to clean safety belts. In
addition, safety belt webbing
should be neither bleached nor
redyed. Failure to observe these
precautions can lead to the
performance or strength of the
safety belts being impaired. In the
case of a collision, therefore, the
safety belts could be insufficiently
effective, and serious
life-threatening injuries could
result. When cleaning, use warm
water in which a small amount of

Warning (Continued)
neutral detergent has been
dissolved to gently wipe the
safety belts.
Follow the manufacturer's advice
whenever cleaning agents or
other chemicals are used, inside
or outside the vehicle. Some
cleaners may be poisonous or
flammable, and improper use may
cause personal injury or damage.
When cleaning the inside or
outside of the vehicle, do not use
volatile cleaning solvents, such as
acetone, lacquer thinners, enamel
reducers, nail polish removers; or
such cleaning materials as
laundry soaps, bleaches or
reducing agents, except as noted
in the following fabric cleaning
advice on stain removal. Never
use carbon tetrachloride,
gasoline, benzene or naphtha for
any cleaning purpose.(Continued)
Warning (Continued)
Open all vehicle doors for
ventilation when ANY cleaning
agents or other chemicals are
used in the interior. Overexposure
to some vapors may result in a
health problem that is more likely
to occur in small, unventilated
spaces.
You and others could be seriously
injured.
The interior of the vehicle must
never be cleaned using acidic or
alkaline solvents, or petroleum
ether, gasoline, and other organic
solvents. Failure to observe this
precaution can result in
discoloration and staining. It should
be noted that certain types of
cleaning products contain these
compounds. Be sure to read
cleaning product labels carefully.
Air fresheners (liquid, solid, gel or
plate types) must not come into
direct contact with, or spill onto,
interior components such as the air conditioning or audio system.
Compounds contained in these
products can cause discoloration,
staining or peeling of paint.
Glass cleaners that contain these
compounds must not be used to
clean the inside of the windshield or
window glass. To clean the glass,
wipe it using a cloth wet with warm
or cold water.
To avoid possible permanent
discoloration of light colored seats,
Do not let materials with non-fast
colors come into contact with seat
trim materials until these materials
are totally dry. This includes certain
types of casual clothing, such as
colored denims, corduroys, leathers
and suedes; also decorative paper,
With the use of modern trim
materials, it is very important that
you use proper cleaning techniques
and cleaners. Failing to do this on
the first cleaning may result in water
spots, spot rings or setting of stains
or soilage - all of which are more
difficult to remove in a second
cleaning.

342 Vehicle Care
Dust and loose dirt that collect on
interior fabric should be removed
often with a vacuum cleaner or soft
bristle brush. Wipe vinyl or leather
trim regularly with a clean, damp
cloth. Normal trim soils, spots or
stains can be cleaned with these
cleaners.
Remember these basic steps before
cleaning:
.Remove stains as quickly as
possible before they
become "set".
. Use a clean cloth or sponge,
and change to a clean area
often. A soft brush maybe used
if stains persist.
. Use solvent-type cleaners only
in a well ventilated area: also, do
not saturate the stained area.
. If a ring forms after spot
cleaning, clean the entire area
immediately.
. Follow specific instructions on
cleaner labels.General Cleaning of Soiled or
Water Spotted Fabric Type
Trim with Foam Type Cleaner
Vacuum the area thoroughly to
remove any loose dirt.
Always clean a whole trim panel or
section. Mask surrounding trim
along stitch or welt lines.
Use suds on a clean sponge. Do
not brush wet suede. Do not
saturate the material or rub it
harshly. Immediately after cleaning,
remove suds with a sponge and
rinse with a clean wet sponge. Wipe
off remaining residue with a slightly
damp absorbent towel or cloth.
Important —Immediately after
wiping, force-dry the fabric with an
air hose. A heat dryer or heat lamp
may be used. Use caution with a
heat dryer or lamp to help prevent
damage.
When trim materials with a sheen or
luster finish are dry, wipe the fabric
lightly with a soft, dry, clean cloth to
restore its sheen or luster. For suede, raise nap with dry scrub
brush and vacuum to remove any
final traces of residue.Spot Cleaning Fabric Type
Trim with Solvent Type Cleaner
Before trying to remove a spot or
stain from fabric, try to find out the
type and age of the spot or stain.
Some spots or stains can be
removed with water or a mild soap
solution. Spots or stains should
always be removed as soon as
possible.
Some types of stains or soilage,
such as lipstick, inks and grease,
are very difficult (sometimes
impossible) to remove completely.
When cleaning this type of stain or
soilage, be sure not to enlarge the
soiled area.
.
Gently scrape excess stain from
the trim material with a clean,
dull knife or scraper. Use very
little cleaner, light pressure, and
clean cloths (preferably
cheesecloth). Cleaning should
start at the outside of the stain

Vehicle Care 343
"feathering" towards the center.
Keep changing to a clean
section of cloth.
. When you clean a stain from
fabric, immediately dry the area
with an air hose, heat dryer,
or heat lamp to help prevent a
cleaning ring. (Use caution with
heat dryer or lamp to help
prevent fabric damage.)
. If a ring forms, immediately
repeat the cleaning operation
over a slightly larger area with
emphasis on "feathering"
towards its center. If a ring still
remains, mask off surrounding
trim sections and clean the
entire soiled area with foam type
cleaner.
See “Removal of Specific
Stains.”
Removal of Specific Stains
Greasy or Oily Stains –Includes
grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing
gum, cosmetic creams, vegetable
oils, wax crayon, tar and asphalts. .
Carefully scrape off excess
stain; then use solvent type
cleaner.
. Shoe polish, wax crayons, tar
and asphalts will stain if left on
trim; they should be removed as
soon as possible. Use care as
cleaner will dissolve them and
may cause them to "bleed".
Non-Greasy Stains –Includes
catsup, coffee (black), egg, fruit,
fruit juice, milk, soft drinks, wine,
vomit and blood.
. Carefully scrape off excess
stain; then sponge the stain with
cool water.
. If a stain remains, use
Multi-Purpose Powdered
Cleaner (Foam type) as
previously described.
. If an odor lingers after cleaning
vomit or urine, treat the area
with a water-baking soda
solution: 5 milliliters (1 teaspoon)
of baking soda to 250 milliliters
(1 cup) of lukewarm water. .
Finally, if needed, clean lightly
with Fabric Cleaner
(Solvent type).
Combination Stains –Includes
candy, ice cream, mayonnaise, chili
sauce and unknown stains.
. Carefully scrape off excess
stain; then clean with cool water
and allow to dry.
. If stain remains, clean it with
Fabric Cleaner (Solvent type).
Cleaning Vinyl Trim
Ordinary soilage can be removed
from vinyl or leather with warm
water and mild soap, such as
saddle soap or oil soap, or an
equivalent.
.Apply a small amount of soap
solution and let it soak for a few
minutes to loosen dirt; then, rub
briskly with a clean, damp cloth
to remove dirt and traces of
soap. This may be done several
times, if needed.
. Soilage such as tars, asphalts,
shoe polish, etc., will stain if left
on trim. They should be wiped
