Maintenance
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially important in dusty or sandy
areas and when the vehicle is used
on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level
ground.
2. Start the engine and allow it to reach normal operating tempera-
ture.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and reinsert it fully. 5. Pull the dipstick out again and
check the level. The level should
be between F and L.
If it is near or at L, add enough oil to
bring the level to F.Do not overfill.
Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil. (Refer to “Recommended lubricantsand capacities” in chapter 8.)
CAUTION - Replacing
engine oil
Do not overfill the engine oil. Itmay damage the engine.
WARNING- Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.
