2009 CHEVROLET COLORADO Owners Manual

Maintenance Footnotes
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, 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, chafing,
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, fittings, and clamps; replace with genuine 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)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades,
if contaminated. Replace wiper blades that are worn or
damaged. See Windshield Wiper Blade Replacement
on page 5-54 and Windshield and Wiper Blades on
page 5-106 for more information.
(e)Make sure the safety belt reminder light and safety
belt assemblies 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 see Checking the Restraint Systems
on page 1-77.
(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.
6-7

(g)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.
(h)Change automatic transmission fluid and filter if the
vehicle is mainly driven under one or more of these
conditions:

for what to use. Inspect hoses. Clean radiator,
condenser, pressure cap, and filler neck. Pressure
test the cooling system and pressure cap.
(j)If driving regularly under dusty conditions, inspect the
filter at each engine oil change.
(k)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.Owner Checks and Services

downhill. Keeping your foot on the regular brake,
set the parking brake.
To check the parking brake’s holding ability: With
the engine running and transmission in N (Neutral),
slowly remove foot pressure from the regular
brake pedal. Do this until the vehicle is held by
the parking brake only.
To check the P (Park) mechanism’s holding ability:
With the engine running, shift to P (Park). Then
release the parking brake followed by the regular
brake.
Contact your dealer/retailer if service is required.
