Cooling System Service* -- Drain, flush and refill the system with newor 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.

“SG”
designation may
be
shown alone or
in
combination
with
others, such as “SH/CD,” “SG/CD” or
“SH,
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.
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

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).
Camshaft
Timing Belt Inspection (3.4L Code
X
engine
only)*
--
Inspect for cracks, wear
or oiliness. Check
tensioner for proper operation. See the service manual. (To
purchase a service manual, see “Service Publications”
in
the Index.) Replace
parts as needed.
Cooling System Service*
--
Drain,
flush
and
refill the
system
with
newor 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
andreplace
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.
I
To
help ensure proper operation,
we
recommend a pressure
test of
both
the cooling system
and
the
pressure
cap.
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
perfoped at the indicated intervals and the maintenance be recorded
in
“Section E:Maintenance Record”.
