Explanation of Scheduled
Maintenance Services
Following 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 engine requires a
special oil meeting GM Standard
GM4718M. Oils meeting this
Standard may be identified as
synthetic, and should also be
identified as API Service
SH or
SG. However, not all Synthetic
API Service
SH oils will meet

NO. SERVICE
this GM Standard. You should
look for and use only an oil that
meets GM Standard GM4718M.
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.
Your vehicle has an Engine Oil
Life Monitor. This monitor will
show you when to change the oil
- usually between 3,000 miles
(5 000 km) and 7,500 miles
( 12 500 km) since your last oil
change. Under severe conditions
the indicator may come on before
3,000 miles
(5 000 km). Never
drive your vehicle more than
7,500 miles (12
500 km) or 12
months without an oil change.
The system won’t detect dust in
the oil..
So if you drive in a dusty
area be sure
to change your oil
every 3,000 miles
(5 000 km) or
sooner if the “Change Oil” light
comes on.

Lubricate the transmission shift
linkage, and parking brake cable guides, underbody contact points
and linkage.
Engine Accessory Drive Belt(s) Inspection

proper tension. Replace as needed. (Belts can have many
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 and boil protection,
corrosion inhibitor level and
maintains proper 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.
To help ensure proper operation,
we recommend a pressure test of
both the cooling system and the
pressure cap.
5 Transmission Service - For
manual transmissions, fluid
doesn’t require changing. See
“Periodic Maintenance
Inspection.”
For automatic transmissions,
change both the fluid and filter

higher.
In hilly or mountainous
terrain.
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 66 000 km).
Replace spark plugs with the
proper type. See “Replacement
