- For the manual transmission and
transfer case, check the fluid level every
time the oil
is changed. See “Manual Transmission Fluid” and
“Transfer Case”
in the Index. Inspect for damage
and leaks and change the fluid the first time at
7,500
miles (12 500 km) and then every 15,000 miles
(25 000 km) or 15 months for Schedule I conditions
and every
30,000 miles (50 OOO km) or 30 months
for Schedule
I1 conditions.
For the automatic transmission, check the fluid level
every time the oil is changed. See “Automatic
Transmission Fluid”
in the Index. Inspect for
damage and leaks and change the
fluid every 15,000
miles (25 OOO km) or 15 months for Schedule I
conditions and

Park
on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake: With the engine running and transmission in Neutral, slowly
remove foot pressure from the regular brake pedal.
Do this until the vehicle is held by the
parking brake only.
To check the P (Park) mechanism’s holding ability: Shift to P (Park). Then release all brakes.
If your vehicle is four-wheel drive, be sure your transfer case is not in Neutral.
At least every spring, use plain water to flush any corrosive materials from the underbody. Take
care to clean thoroughly any areas where mud and other debris can collect.

Section C: Periodic Maintenance Inspections
Listed below are inspections and services which should be
performed at least twice a year (for instance, each spring or
fall). You should let your
GM dealer’s service department or
other qualified service center do these
jobs. Make sure
any necessary repairs are completed at once.

Inspection
Throttle Linkage
Inspection
Rear Axle (All) and
Front Axle
(Four-wheel Drive)
Service ~ Inspect front and rear suspension and steering system for damaged, loose or missing parts, signs
of wear or lack of lubrication. On vehicles equipped with power steering, inspect power steering,
lines and hoses for proper hookup, binding, leaks, cracks, chafing, etc. On vehicles equipped
with manual steering, check
for seal leakage. Clean and then inspect drive axle boot seals for
damage, tears or leakage. Replace seals
if necessary.
Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken,
damaged, missing,
or out-of-position parts as well as open seams, holes, loose connections, or
other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes
into the vehicle. See “Engine Exhaust’’
in the Index.
Inspect the throttle linkage for interference or binding, and for damaged or missing parts.
Replace parts as needed. Check accelerator pedal for smooth operation and even pedal effort.
Check the gear lubricant level and add if needed. See “Rear Axle’’ and ‘‘Four-wheel Drive’’
in
the Index. A fluid loss may indicate a problem. Check the system(s), and repair the system(s) if
needed. Refer to “Scheduled Maintenance Services,” earlier in this part, to determine when to
change
the lubricant.
