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

352 Service and Maintenance
7. SPARK PLUGS :Change every
160 000 km (100,000 miles).
8. SPARK PLUG WIRES : Clean
wires and inspect for burns, cracks
or other damage. Check the wire
boot fit at the coilpack and at the
spark plugs. And replace every
160 000 km (100,000 miles).
9. FUEL TANK, CAP AND LINES :
Inspect the fuel tank, cap and lines
for damage or leaks. Remove fuel
cap, inspect gasket for an even filler
neck imprint, and any damage.
Replace parts as needed.
10. ENGINE ACCESSORY DRIVE
BELT(S) : Inspect belts. Look for
cracks, fraying, wear, and proper
tension. Adjust or replace as
needed, and change every
160 000 km (100,000 miles).
11. EVAPORATIVE CONTROL
SYSTEM (ECS) : Visually check all
fuel and vapor lines and hoses for
proper hookup, routing, and
condition. Check that bowl vent and
purge valves work properly,
if equipped. Replace as needed. 12. SHIELDS AND UNDER HOOD
INSULATION :
Inspect shields and
under hood insulation for damage or
looseness. Adjust or replace as
required.
13. AIR INTAKE SYSTEM : Check
the air intake system installation to
see that gaskets are seated
properly and all hose connections,
fasteners, and other components
are tight. Also check to be sure that
the air cleaner housing is properly
seated, that the cover fits tightly,
and the wingnut(s) is/are tight.
Tighten connections and fasteners
or replace damaged parts as
required.
14. THERMOSTATICALLY
CONTROLLED ENGINE COOLING
FAN : With the engine off and below
normal operating temperature,
check to see that the fan can be
rotated by hand on fluid coupling or
viscous drives. Replace as
necessary. 15. AUTOMATIC TRANSMISSION
FLUID :
Check the automatic transmission
fluid level at each engine oil change
and replace fluid every 84 000 km
(52,500 miles). To check the fluid
level, first set the parking brake,
then start the engine in "P" position.
With the regular brakes applied,
move the selector lever through all
the gear positions, ending with "P".
You must check the fluid level with
the engine running at slow idle and
the truck must be on a level surface.
