1993 BUICK LESABRE brake fluid

Explanation of Scheduled Maintenance
Services
Below are explanations of the services listed in Schedule
I and Schedule 11.
The proper fluids and lubricants to use are listed in
Section
D. Make sure whoever services your vehicle
uses these. All parts should be replaced and all
necessary repairs done before
you or anyone else drives
the vehicle.
1. Engine Oil and Filter Change* -- Always use SG
Energy Conserving I1 oils of proper viscosity. The
“SG” designation may be shown alone or in
combination with others, such as “SG/CC”,
“SG/CD” or “SF, SG, CC,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g.,
SAE
5W-30 or SAE 10W-30), see “Engine Oil” in
the Index. If your vehicle has an Engine Oil Life
Monitor, the monitor will show
you when to change
the oil. See “Engine Oil Life Monitor” in the Index.
2. Chassis Lubrication -- Lubricate suspension and
steering linkage. Lubricate the transaxle shift linkage, and parking brake
cable guides, underbody
contact points and linkage.
3. Throttle Body Mounting Bolt Torque* -- Check
the torque of the mounting bolts and/or nuts.
4. Tire and Wheel Rotation and Inspection -- For
proper wear and maximum tire life, rotate your tires
following
the instructions in this manual. See “Tires,
Inspection
& Rotation” in the Index. Check the tires
for uneven wear or damage. If you see irregular or
premature wear, check the wheel alignment. Check
for damaged wheels also.
5. Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
6. Cooling System Service” -- Drain, flush and refill
the system with new or approved recycled coolant
conforming to GM Specification 1825M. Keep
coolant at the proper mixture as specified. See
“Coolant” in
the Index. This provides proper freeze
protection, corrosion inhibitor level
and engine
operating temperature.
* An Emission Control Service.
3‘ The U.S. Environmental Protection Agency has determined that the failure to perfonn this maintenance item will not nullify the emission warranty or limit recall liability prior to thecompletion of vehicle
useful life. General Motors, however, urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded in “Section E:Maintenance Record”.

INSPECTION OR SERVICE
Brake System
Inspection
WHAT SHOULD BE DONE
Inspect the complete system. Inspect
brake lines and hoses for proper hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads
for wear and rotors for surface
condition. Inspect other brake parts, including calipers, parking brake,
etc. Check parking brake
adjustment.
You may need to have
your brakes inspected more often
if
your driving habits or conditions
result in frequent braking.
NOTE:
A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced. Also,
if the
brake system warning light stays on
or comes on, something may be
wrong with the brake system. See
“Brake System Warning Light” in
the Index. If your anti-lock brake
system warning light stays
on or
comes on, something may be wrong
with the anti-lock brake system. See
“Anti-Lock Brake System Warning
Light” in the Index.
Section D: Recommended Fluids and
Lubricants
NOTE: Fluids and lubricants identified below by name,
part number
or specification may be obtained from your
GM dealer.

“SF,SG,CC,” etc.
To determine the
preferred viscosity for your vehicle’s
engine, see “Engine Oil’’ in the
Index.
