Engine Oil Filter SelectionAll of this manufacturers 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
TENSIONAt 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, see your authorized dealer for service.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 PLUGSSpark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Refer to “Fluids, Lubricants, and Genuine Parts” in
this section for the proper type of spark plug for use in
your vehicle.IGNITION WIRING SYSTEMThe ignition cables should be kept clean and properly
connected. Terminals should be fully seated. Cracked,
damaged, or faulty cables should be replaced.
