ENGINE OIL ADDITIVES
In some instances, such as infrequent operation,
short trip driving, and during break-in after a major
overhaul, addition of special materials containing an­
ti-rust and anti-scuff additives are beneficial. A suit­
able product for this purpose is MOPAR Engine Oil
Supplement.
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 ki­
lometers (500 miles). Unless the engine has exhibited
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.
(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. 3).

dipstick.

ENGINE OIL FILTER
OIL FILTER SPECIFICATION
Chrysler Corporation recommends a Mopar or
equivalent oil filter be used when replacement is re­
quired. A replacement filter must be designed to
withstand 1756 kPa (256 psi) of internal pressure.
OIL FILTER REMOVAL
(1) Position a drain pan under the oil filter.
(2) Using a suitable oil filter wrench (Fig. 4) loosen
filter by turning counterclockwise.
(3) When filter separates from adapter nipple, tip
gasket end upward to minimize oil spill. Remove fil­
ter from vehicle.
(4) With a wiping cloth, clean the gasket sealing
surface (Fig. 5) of oil and grime.
OIL FILTER INSTALLATION
(1) Lightly lubricate oil filter gasket with engine
oil or chassis grease.
(2) Thread filter in a clockwise motion onto
adapter nipple. When gasket makes contact with
sealing surface, hand tighten filter one full turn, do
not over tighten.
(3) Add oil, verify crankcase oil level and start en­
gine. Inspect for oil leaks.
