Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil and oil filters, indiscriminately
discarded, can present a problem to the environment.
Contact your authorized dealer, service station, or gov-
ernmental agency for advice 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 the 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 appropriate “Maintenance
Schedule,” check all drive belts for condition and proper
tension. Improper belt tension can cause belt slippage
and failure.
Inspect the drive belt 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 specifications
and procedures shown in the 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.
