OIL LEVEL INDICATOR (DIPSTICK)
The engine oil level indicator is located at the right
rear of engine on 4.0L engines (Fig. 6) and the right
front of the engine on 5.2L engines (Fig. 7).
CRANKCASE OIL LEVEL INSPECTION
CAUTION:
Do not overfill crankcase with engine
oil, oil foaming and oil pressure loss can result.
Inspect engine oil level approximately every 800
kilometers (500 miles). Unless the engine has exhib-
ited loss of oil pressure, run the engine for about five
minutes before checking oil level. Checking engine oil
level on a cold engine is not accurate.
To ensure proper lubrication of an engine, the
engine oil must be maintained at an acceptable level.
The acceptable levels are indicated between the ADD
and SAFE marks on the engine oil dipstick (Fig. 8).
(1) Position vehicle on level surface.
(2) With engine OFF, allow approximately ten min-
utes for oil to settle to bottom of crankcase, remove
engine oil dipstick.
(3) Wipe dipstick clean.
(4) Install dipstick and verify it is seated in the
tube.
(5) Remove dipstick, with handle held above the
tip, take oil level reading (Fig. 8).
(6) Add oil only if level is below the ADD mark on
dipstick.

described in Maintenance Schedules.
Run engine until achieving normal operating tem-
perature.
