1998 CHEVROLET EXPRESS Owners Manual

Downloaded from www.Manualslib.com manuals search engine Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are not
removed, accelerated corrosion (rust) can occur on
the underbody
parts such as fuel lines, frame, floor
pan and exhaust system even though they have
corrosion protection.
At least every spring, flush these materials from the
underbody with plain water. Clean any areas where mud
and other debris can collect. Dirt packed in closed areas
of the frame should be loosened before being flushed.
Your dealer or an underbody car washing system can do
this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create
a chemical fallout. Airborne pollutants can fall upon
and attack painted surfaces on your vehicle. This
damage can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched
into the paint surface.
Although no defect
in the paint job causes this, GM
will repair, at no charge to the owner, the surfaces of
new vehicles damaged by this fallout condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever occurs first.
This applies only to materials manufactured and sold by
General Motors. Bodies, body conversions
or equipment
not made or sold by General Motors are not covered.

Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment
can keep other components from working
as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle,
see “Servicing
Your Air Bag-Equipped Vehicle”
in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps to flicker on and off, or in some cases to remain
off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker and a fuse.
If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
Although the circuit
is protected from electrical
overload, overload due to heavy snow, etc., may cause
wiper linkage damage. Always clear ice and heavy snow
from the the windshield before using the windshield
wipers.
If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.

The fuse block access door
is
on the driver’s side of
the instrument panel above
the hood release lever.
You can remove the cover
by turning the fastener to
the left.
You can remove fuses with
a fuse extractor. The fuse
extractor
is mounted to the fuse block access door.
To remove fuses if you don’t have a fuse extractor, hold
the end of the fuse between your thumb and index finger
and pull straight out. Be
sure
to use the correct fuse. If you ever have a
problem on the road and don’t have a spare fuse,
you can borrow one of the correct value. Just pick
some feature of your vehicle that
you can get along
without
-- like the radio or cigarette lighter -- and use
its fuse, if it is of the value you need. Replace it as
soon as you can.
