MAINTENANCE & LUBRICATION
06-5
A-2-FLUID LEVELS
-
Check level of fluid in brake
master cylinder.,
power steering p u m p , battery, engine*,
axle, transmission* and windshield washera. Engine coolant
should be checked for proper level and freeze protection to
at least -20°F. (-29°C.) or to the lowest temperature expected
during the period of vehicle operation.* Proper engine
coolant also provides corrosion protection.
Any significant fluid loss in any of these systems or units
could mean that a malfunction is developing and corrective
action should be taken immediately. A low fluid level in the
brake master cylinder front reservoir could also be an
indicator that the disc brake pads need replacing.
A-3-ENGINE OIL*
-
Change each 12 months or 7,500
miles, whichever occurs first under normal driving
conditions, or each 3 months or 3,000 miles when the vehicle
is operated under the following conditions: (a) driving in
dusty conditions, (b) trailer pulling, (c) extensive idling or (d)
short-trip operation at freezing temperatures (with engine not
thoroughly warmed-up). See your Owner's Manual for
additional details on engine oil.
A-4-ENGINE OIL FILTER* Replace at the first oil
change and every other oil change thereafter, if mileage (7,-
500 miles) is the determining factor. If time (12 months) is
the determining factor, then change oil filter with every oil
change.
A-5-TI R ES
-
To equalize wear, rotate tires as described
in Section on Wheels and Tires and adjust tire pressures as
shown on tire placard on glove box door or edge of door. Steel
belted radial tires should be rotated at first 7,500 miles and
then at every 15,000 miles thereafter. Bias-belted tires should
be rotated every 7,500 miles.
A-6-REAR AXLE
-
Change lubricant every 15,000
miles on all type rear axles or final drives when using vehicle
to pull a trailer.
A-7-AIR CONDITIONING
-
Check condition of air
conditioning system hoses and refrigerant charge at sight
glass (if so equipped). Replace hoses and/or refrigerant if
need is indicated.
A-8-COOLING SYSTEM*
-
At 12-month or 15,000-
mile intervals, wash radiator cap and filler neck with clean
water, pressure test system and radiator cap for proper
pressure holding capacity (tighten hose clamps and inspect
conditions of all cooling and heater hoses). Replace hoses if
checked, swollen or otherwise deteriorated.
Also each 12 months or 15,000 miles, clean exterior of
radiator core and air conditioning condenser. Every 24
months or 30,000 miles, drain, flush, and refill the cooling
system with a new coolant solution as described in your
Owner's Manual.
A-9-WHEEL BEARINGS
-
Clean and repack front
wheel bearings with a lubricant meeting requirements of GM
603 1-M.
A-1 0-MANUAL STEERING GEAR -Check for seal
leakage around the pitman shaft and housing. If leakage is
evident (solid grease oozing out
-
not just oily film), it should
be corrected immediately.
A-1 1 -CLUTCH CROSS SHAFT
-
Lubricate clutch
cross shaft lever.
A-1 2-AUTOMATIC TRANSMISSION FLUID*
-
Under normal driving conditions, change the transmission
fluid and service the sump filter every 60,000 miles. On 250
series transmissions, adjust the intermediate band at fluid
change intervals.
Under unusual conditions, such as constant driving in
heavy city traffic, trailer pulling, and commercial
applications, services should be performed at 15,000-mile
intervals.

SECTION B
-
SAFETY
MAINTENANCE
NOTE: Items B- 1 (a) thru (w) can be checked by the
owner, while items B-2 thru B-10 should only be checked
by a qualified mechanic. It is particularly important that
any safety system which may have been adversely
affected in an accident be checked and repaired as
necessary before the vehicle is returned to use.
6-1-SAFETY CHECKS TO BE PERFORMED BY
OWNER
-
The following checks should be made regularly
during operation at no greater interval than 12 months or
7,500 miles, whichever occurs first, and more often when the
need is indicated. Any deficiencies should be brought to the
attention of your dealer or another service outlet, as soon as
possible, so the advice of a qualified mechanic is available
regarding the need for repairs or replacements.
a. STEERING COLUMN LOCK
-
Check for proper
operation by attempting to turn key to LOCK position in the
various transmission gear ranges when the car is stationary.
Key should turn to LOCK position only when transmission
control is in PARK on automatic transmission models or in
reverse on manual transmission models. Key should be
removable only in LOCK position.
STEERING COLUMN LOCK (ASTRE, SUNBIRD
AND 5-SPEED VENTURA)
-
Check for proper operation
by attempting to turn key to LOCK position without
depressing key release lever with car stationary. Key should
turn to LOCK position only with key release lever depressed.
Key should be removable only in LOCK position.
b. PARKING BRAKE AND TRANSMISSION
"PARK" MECHANISM
-
Check parking brake holding
ability by parking on a fairly steep hill and restraining the
vehicle with the parking brake only. On cars with automatic
transmissions, check the holding ability of the "PARK"
mechanism by releasing all brakes after the transmission
selector lever has been placed in the " P position.
CAUTION: Before making checks (c) or (d)
below, be sure to have a clear distance ahead and
behind the car, set the parking brake and firmly
