PART 8: MAINTENANCE AND SERVICE
PB1319 (CAT. NO. 5296 ) —159— 22-01691 (R02/02)
• Check the evaporator core and condenser core for debris restrict-
ing air flow. Clean if necessary. Small particles may be removed
with compressed air blown through the core in the opposite direc-
tion of normal air flow.
• Verify that hoses are routed around the pivot point so that lifting
the cab does not strain them.
• Check hoses for kinks, deterioration, chafing, and leaks. Adjust
kinked or chafing hoses to eliminate restrictions and prevent fur-
ther wear.
• Check all components and connections for refrigerant leaks. If you
discover a leak, don’t try to tighten a connection. Tightening a
connection may cause a worse leak. Have a qualified technician
correct the problem.
• Have the air conditioning system inspected annually by a dealer.
Appearance
Painted Surfaces
• Wash frequently to remove grime and caustic deposits that may
stain the finish. Apply cool or lukewarm water. You may want to
use a mild soap.
• Avoid washing your vehicle in bright sunlight.
• Road tar may be removed with a special commercial tar remover
or mineral spirits.
• Waxing offers added protection against staining and oxidation. But
to allow enough time for your truck’s finish to cure, wait about ninety
days after the date of manufacture before waxing. Don’t wax in the
hot sun. Don’t friction-burn the paint with a buffing machine.
CAUTION: Small particles blown by compressed air
could injure your eyes. Wear eye protection any time
you blow compressed air.
NOTE: A leaking evaporator or condenser core cannot be
repaired; it must be replaced.
CAUTION: Do not aim the water jet directly at door locks or
hatch. Tape the key holes to prevent water from seeping into
the lock cylinders. Water in lock cylinders should be removed
with compressed air. To prevent locks from freezing in the
winter, squirt glycerin or lock deicer into the lock cylinders.
WARNING! Handle cleaning agents carefully. The agents
may be poisonous. Keep them out of the reach of children.
