Maintenance Footnotes
(a)Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks, chang, etc.
Inspect disc brake pads for wear and rotors for
surface condition. Inspect drum brake linings/shoes
for wear or cracks. Inspect other brake parts,
including drums, wheel cylinders, calipers, parking
brake, etc. Check parking brake adjustment.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing
parts or signs of wear. Inspect power steering lines
and hoses for proper hook-up, binding, leaks,
cracks, chang, 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, body door and
fuel door hinges, latches and locks (including glove
box and console doors), hood latch assembly,
secondary latch, pivots, spring anchor, release
pawl, and any moving seat hardware. Lubricate
hood safety lever pivot and prop rod pivot and
tailgate latch bolt, handle assembly pivot points,
and hinges. 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.
