CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.
Frequency Of Oil Change
Road conditions and your style of driving affect the
interval at which your oil should be changed. Check the
following to determine if any apply to you:
²Day or night temperatures are below 32ÉF (0ÉC).
²Stop and go driving.
²Extensive engine idling.
²Driving in dusty conditions
²Short trips of less than 10 miles (16.2 km)
²More than 50% of your driving is at sustained high
speeds during hot weather, above 32ÉC (90ÉF)
²Trailer towing
²Taxi, Police or delivery service (commercial service)
²Off-road or desert operation
²If equipped for and operating with E-85 (ethanol)
fuel.
NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule ªBº of the
9Maintenance Schedules9section of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on schedule9A9of the9Mainte-
nance Schedules9section of this manual.
4x4 Models, If Used Primarily For Off-Road
Operation

The radiator normally remains completely full, so there is
no need to remove the pressure cap except when check-
ing coolant freeze point or when replacing coolant. Your
service attendant should be advised of this. When addi-
tional coolant is needed to maintain the proper level, it
should be added to the overflow bottle. Do not overfill.
Points To Remember
A. Do not overfill the reserve tank (overflow bottle).
B. Check coolant freeze point in the radiator and in the
reserve tank. If antifreeze needs to be added, contents of
reserve tank also must be protected against freezing.
C. If frequent coolant additions are required, or if the
level in the reserve tank does not drop when the engine
cools, the cooling system should be pressure tested for
leaks.D. Maintain a minimum coolant concentration of 50%
ethylene glycol.
E. Make sure that the radiator and reserve tank overflow
hoses are not kinked or obstructed.
F. Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean also.
G. The thermostat should not be changed for summer or
winter operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance.
Emission Related Components
Fuel System Hoses And Vapor/Vacuum Harnesses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, checking, tears, cuts, abrasions, and excessive
swelling suggest deterioration of the rubber. Particular
attention should be given to examining hose surfaces
nearest to high heat sources, such as the exhaust mani-
fold.

Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:Fluids such as oil, power steering fluid, and
brake fluid are used during assembly plant operations to
ease the assembly of hoses to couplings. Therefore, oil
wetness at the hose-coupling area is not necessarily an
indication of leakage. Actual dripping of hot fluid when
systems are under pressure (during vehicle operation),
should be noted before hose is replaced based on leakage.
You are urged to use only manufacturer specified hoses
and clamps, or their equivalent in material and specifi-
cation, in any fuel system servicing. It is mandatory to
replace all clamps that have been loosened or removed
during service. Care should be taken in installing new
clamps to insure they are properly torqued.
Positive Crankcase Ventilation (PCV) Valve
Proper operation of the crankcase ventilation system
requires that the PCV valve be free of sticking or plug-
ging because of deposits. Deposits can accumulate in thePCV valve and passage with increasing mileage. Have
the PCV valve, hoses, and passages checked for proper
operation at the intervals specified. If the valve is
plugged or sticking, replace with a new valve.Do not
attempt to clean the oil PCV valve!Check ventilating
hose for indication of damage or plugging with deposits.
Replace if necessary.
242 MAINTAINING YOUR VEHICLE
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
²
Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
²Check the windshield washer solvent and add if
required.
Once a Month
²
Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder, and transmission and add as needed.
²Check all lights and all other electrical items for correct
operation.
At Each Oil Change
²
Change the engine oil filter.
²Inspect the exhaust system.
²Inspect the brake hoses.
²Inspect the CV joints (if equipped) and front suspen-
sion components.
²Check the automatic transmission fluid level (if
equipped).
²Check the manual transmission fluid level (if
equipped).
²Check the coolant level, hoses, and clamps.
Tire Rotation
²
Rotate the tires every 6,000 miles (10 000 km).
