Chevrolet 2007 Monte Carlo Owner's Manual page 411

(f) Lubricate all key lock cylinders. Lubricate all
hinges and latches, including those for the
body doors, hood, secondary latch, pivots, spring
anchor, release pawl, rear compartment, glove
box door, console door, and any 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) If you drive regularly under dusty conditions,
the filter may require replacement more often.
(h) Change automatic transaxle 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 320 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and filler neck. Pressure test the cooling
system and pressure cap.
(j) Check throttle system for interference or
binding and for damaged or missing parts. Replace
parts as needed. Replace any components that
have high effort or excessive wear. Do not
lubricate accelerator or cruise control cables.
(k) 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.
(m) If you drive regularly under dusty conditions,
inspect the filter at each engine oil change.
(n) Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
