applied. This does not mean something is wrong with
your brakes.
Rear Drum Brakes
Your rear drum brakes don’t have wear indicators, but if
you ever hear
a rear brake rubbing noise, have the rear
brake linings inspected. Also, the rear brake drums should be removed and inspected each time the tires are
removed for rotation
or changing. When you have the
front brakes replaced, have the rear brakes inspected,
too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel. This
could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop, your
brakes adjust for wear.
If you rarely make a moderate or heavier stop, then your
brakes might not adjust correctly. If you drive in that
way, then
-- very carefully -- make a few moderate brake
stops about every
1000 miles (1600 km), so your
brakes will adjust propexly.
Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same time.
In many emergencies, steering can help you more than
even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system fails to function, you can steer but it
will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver
lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each
of us is subject to
the same laws of physics when driving
on curves. The
traction
of the tires against the road surface makes it
possible for the vehicle to change its path when you turn

Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When
you replace your thermostat, an ACS thermostat
is recommended.
Power Steering Fluid

How To Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then remove
the cap again and look at the fluid level on the dipstick.
When the engine compartment is hot, the level
When the engine compartment is cool, the level
What to Add:
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants” in the Index.
should be
at the
“HOT” mark.
should be at the
“FULL COLD” mark.
When adding power steering fli or making a
complete fluid change, always use the proper
fluid. Failure
to use the proper fluid can cause
leaks and damage hoses and seals.

Section C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall). You should let your
GM dealer’s
service department or other qualified service center do
these jobs. Make sure any necessary repairs are completed at once.

WHAT SHOULD BE DONE
Inspect the front and rear suspension
and steering system for damaged,
loose or missing parts, signs of wear,
or lack of lubrication. Inspect the
power steering lines and hoses for
proper hookup, binding,
leaks,
cracks, chafing, etc. Clean and then inspect the drive axle boot seals for
damage, tears
or leakage. Replace
seals if necessary.
Inspect the complete exhaust system. Inspect the body near the
exhaust system. Look for broken,
damaged, missing or out-of-position
parts as well as open seams, holes,
loose connections, or other
conditions which could cause a heat
build-up in the floor pan or could let
exhaust fumes into the vehicle. See
“Engine Exhaust” in the Index.
Inspect the throttle linkage for
interference or binding, and for
damaged
or missing parts. Replace
parts as needed.
