If a flush is needed because of component malfunc-
tion, use only the specified fluid for the flushing
procedure.
Engine Oil
Checking Oil Level — 3.6L Engine
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as once a month. The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level between the MIN and MAX markings on the dipstick. Adding 1.0 quart (1.0 liter) of oil when the
reading is at the MIN mark will result in a MAX reading
on these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Checking Oil Level — 5.7L and 6.4L Engine
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level in the “SAFE” range. Adding 1.0 quart (1.0
liter) of oil when the reading is at the bottom of the
