Change engine oil and filter (or every 3 months, whichever occurs
first).
An Emission Control Service.
Lubricate the front suspension, king pin bushings, steering linkage,
transmission shift linkage, transfer case shift linkage, parking brake
cable guides, rear driveline center splines, front axle propshaft splines,
brake pedal springs and clutch pedal springs. Ball joints and king pin
bushings should not be lubricated unless their temperature is
10" F
(-12" C), or higher. When weather is cold, let the ball joints and king
pin bushings warm up before lubrication or they could be damaged.
Perform each of the listed lubrication service items at this mileage
interval (or every 12 months, whichever occurs first).
For vehicles equipped with a 5-speed manual transmission with deep
low: Lubricate the clutch fork ball stud through the fitting
on the clutch
housing. Lubricant must be added
spring1-y to the fitting, as very little
is required to lubricate the ball stud surface. Do not add lubricant more
often than specified.
Too much lubricant will damage the clutch
assembly.
Drain, flush and refill the cooling system with new coolant (or every 24
months, whichever occurs first). See "Engine Coolant" in the Index for
what to use.
An Ernission Control Service.
Also inspect the hoses and replace them if they are cracked, swollen or
deteriorated. Tighten all hose clamps (except constant tension clamps).
Remove debris and clean the outside of the radiator and air
conditioning condenser. Wash the radiator neck.
To ensure proper
operation, pressure test the radiator and cap.
Replace air cleaner filter.
An Emission Coratrol Service.
For 2-Wheel Drive vehicles only: Clean and repack the front wheel
bearings (or at each brake relining, whichever occurs first).
Replace fuel filter. Replace filter sooner
if it is clogged:?
Inspect shields and underhood insulation for damage or looseness.
Adjust
or replace as required. This is a Noise Emission Control
Service. Applicable only to vehicles sold in the United States.

Part B: Owner Checks and Services
Listed below are owner checks and services which should be performed at
the intervals specified to help ensure the safety, dependability and emission
control performance of your vehicle.
Be sure any necessary repairs are completed at once. Whenever any fluids
or lubricants are added to your vehicle, make sure they are the proper ones,
as shown in Part D.
At the First 100, 1,000 and 6,000 Miles (160, I 600 and
IO 000 km)
For vehicles with dual wheels, check dual wheel nut torque. For proper
torque, see “Wheel
Nut Torque’’ in the Index.
At Each Fuel Fill
Engine Oil Level
Check the engine oil level and add the proper oil if necessary. See “Engine
Oil”
in the Index for further details.
Engine Coolant Level
Check the engine coolant level and add the proper coolant mix if necessary.
