(f) Lubricate all key lock cylinders, hood latch
assembly, secondary latch, pivots, spring anchor,
release pawl, door hinges, liftgate hinge, liftgate
linkage, liftgate handle pivot points, latch bolt, fuel
door hinge, locks, and folding seat hardware.
More frequent lubrication may be required when
exposed to a corrosive environment. Applying
silicone grease on weatherstrips with a clean cloth
will make them last longer, seal better, and not
stick or squeak.
(g) Inspect system. Check all fuel and vapor lines
and hoses for proper hook-up, routing, and
condition. Check that the purge valve works
properly, if equipped. Replace as needed.
(h) Change automatic transmission fluid and filter
if the vehicle is mainly driven under one or
more of these conditions:
− In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
− In hilly or mountainous terrain.
− When doing frequent trailer towing.
− Uses such as found in taxi, police,
or delivery service.
(i) Drain, flush, and refill cooling system.
This service can be complex; you should have your
dealer perform this service. See Engine Coolant on
page 445 for what to use. Inspect hoses. Clean
radiator, condenser, pressure cap, and filler neck.
Pressure test the cooling system and pressure cap.
(j) A fluid loss in any vehicle system could indicate
a problem. Have the system inspected and repaired
and the fluid level checked. Add fluid if needed.
(k) If you drive regularly under dusty conditions,
inspect the filter at each engine oil change.
(l) Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
(m) Check vent hose at transfer case for kinks
and proper installation.
