Engine Coolant Heater (Engine Block
Heater)
An engine coolant heater can be a big help if you have
to park outside in very cold weather, 0°F (- 18 “C) or
colder. If your vehicle has this option, see “Engine
Coolant Heater”
in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails
with soap and
water,
or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine
oil. (See
the manufacturer’s warnings about the use and disposal
of
oil products.)
Used oil can be a real threat to the environment. If you
change your own
oil, be sure to drain all free-flowing
oil from the filter before disposal. Don’t ever dispose of
oil by putting it in the trash, pouring it on the ground,
into sewers, or into streams or bodies of water. Instead,
recycle
it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.
Air Cleaner
The air cleaner is in the right front area of the engine
compartment.
Refer to the Maintenance Schedule to determine when
to replace the air filter.
See “Scheduled Maintenance Services”
in the Index.

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.
NOTE: To determine your engine’s displacement and
code, see “Engine Identification”
in the Index.
1.
Engine Oil and Filter Change* -- Always use SH or
SG Energy Conserving I1 oils of proper viscosity. The
“SH” or “SG” designation may be shown alone or in
combination with others, such as “SH/CD,” “SH, SG,
CD,” “SG/CD” 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.
2. Chassis Lubrication -- Lubricate the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. If your vehicle is
equipped with grease fittings, lubricate the
suspension and steering linkage. 3.
4.
5.
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.
Engine Accessory Drive Belt(s) Inspection -- Inspect
the belt(s) for cracks, fraying, wear and proper tension.
Replace as needed. (Belts can have small cracks
in
individual ribs without affecting performance).
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.
Inspect hoses and replace if they are cracked, swollen
or deteriorated. Tighten screw-type hose clamps.
Clean the outside of the radiator and air conditioning
condenser. Wash the pressure cap and neck.
272
ProCarManuals.com

To help ensure proper operation, we recommend a
pressure test of both the cooling system and the
pressure cap.
6. Transaxle Service -- Change both the fluid and filter
every
15,000 miles (25 000 km) 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 car or delivery
service.
If you do not use your vehicle under any of these
conditions, change both the fluid and filter every
100,000 miles (1 60 000 km).
7.
8.
9.
Spark Plug Replacement* -- Replace spark plugs
with the proper type. See “Specifications Chart” in
the Index.
Spark Plug Wire Inspection*? -- Inspect for burns,
cracks
or other damage. Check the boot fit at the
distributor and at the spark plugs. Replace wires as
needed.
Air Cleaner Filter Replacement* -- Replace every
30,000 miles (50 000 km) or more often under dusty
conditions. Ask your dealer for the proper
replacement intervals for your driving conditions.
10. Fuel Tank, Cap and Lines Inspection*? -- Inspect
fuel tank, cap and lines (including fuel rails and
injection assembly,
if equipped) for damage or leaks.
Inspect fuel cap gasket for an even filler neck
imprint or any damage. Replace parts as needed.
Periodic replacement of the fuel filter is not required.
* An Emission Control Service.
The
U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the
emission warranty or limit recall liability prior to the completion 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”. s
