for lubrication at regular intervals. In addition to
the regular maintenance services at recommended
intervals, throttle linkage, parking brake linkage,
and body parts such as door latches and hinges,
weather
·
stripping,
etc.,
should receive attention
at every oil change. As part of the periodic lu-
brication service, all lubricant and fluid levels
should be checked and replenished as necessary.
• Wheel Alignment and Wheel Balance-are af-
fected by operating conditions such as hitting
chuck holes and curbs, rapid starts and stops,
tire skidding, etc. Wheel alignment and balanc-
ing service contribute to longer tire life and bet-
ter vehicle handling.
• Tire Rotation-Rapid acceleration, quick stops,
vehicle speed and loading affect tire life and can
cause uneven wear. Tires should be rotated
regularly for uniform wear and maximum life.
• Brake Services-Brake linings are subject to
wear from usage depending upon driving con-
ditions and driving habits of each individual
driver.
Periodic check of brake lining condition
by a qualified technician is recommended for safe
operation. When the brake system requires serv-
ice, replace with genuine GM parts.
• Engine Oil Change and Filters-Changing en-
gine oil, and air, fuel and oil filters at recom-
• 37 •
mended intervals is the owner's best investment
in prolonged engine life, efficiency and perform-
ance. When replacement is necessary, always in-
sist on AC ACron filters.
• Transmission Oil Change-Extended use and
contamination affect transmission fluid. To assure
efficient operation, transmission oil pan should be
drained and fresh fluid added, and, strainer re-
placed, at the recommended intervals. DEX-
RON® fluid is recommended for automatic trans-
missions.
• Emission Control-A check of the items affect-
ing vehicle emission control at the first oil change
(4 months or 6,000 miles, whichever occurs first)
is important to control hydrocarbon and carbon
monoxide emissions within levels established by
government standards and thus reduce air pollu-
tion. Subsequent checks should be made every 12
months or 12,000 miles, whichever occurs first.
This check involves the adjustment of engine
idle speed, idle fuel mixture, ignition timing and
an operational check of the Positive Crankcase
Ventilation Valve (PCV) and related parts. Cli-
matic conditions, type of operation, wear and
contamination can affect these engine adjust-
ments and proper functioning of the PCV valve.
Checking for proper operation will not only con-
tribute to the control of exhaust and engine
