on how and where used oil can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
All of this manufacturer’s engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. Mopar Engine Oil Filters are high
quality oil filters and are recommended.
Drive Belts – Check Condition and Tension
At the mileage shown in the maintenance schedules,
check all drive belts for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Inspect the drive belts for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, adjust the belts according to the specificationsand procedures shown in the Service Manual. See the
Consumer Assistance section for information on ordering
a Service Manual.
Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
between the belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the mileage specified in the appropriate main-
tenance chart. The entire set should be replaced if there is
any malfunction due to a faulty spark plug. Check the
specifications section for the proper type of spark plug
for use in your vehicle.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
