(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts, signs of wear, or lack of lubrication. Inspect
power steering lines and hoses for proper
hook-up, binding, leaks, cracks, cha ng, etc.
Visually check constant velocity joints, rubber
boots, and axle seals for leaks.
(c)Visually inspect hoses and have them replaced
if they are cracked, swollen, or deteriorated.
Inspect all pipes, ttings, and clamps; replace with
genuine GM parts as needed. To help ensure
proper operation, a pressure test of the cooling
system and pressure cap and cleaning the outside
of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Visually inspect wiper blades for wear or
cracking. Replace wiper blades that appear worn
or damaged or that streak or miss areas of
the windshield.(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced. Also
look for any opened or broken airbag coverings,
and have them repaired or replaced. The
airbag system does not need regular maintenance.
(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.

lines and hoses for proper hook-up, routing, and
condition. Check that the purge valve works
properly, if equipped. Replace as needed.

hoses. Clean radiator, condenser, pressure
cap, and ller neck. Pressure test the cooling
system and pressure cap.(j)A uid loss in any vehicle system could indicate
a problem. Have the system inspected and
repaired and the uid level checked. Add uid if
needed.
(k)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(l)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
