300 MAINTAINING YOUR VEHICLE Engine Oil Filter The engine oil filter should be replaced at every engine oil change. Engine Oil Filter Selection This manufacturer's engines have a full-flow type oil filter. Use a filter of this type for replacement. The quality of replacement filters varies considerably. Only high quality filters should be used to assure most efficient service. Mopar Engine Oil Filters are a high quality oil filter and are recommended. Drive Belts - Check Condition and Tension Belt tension is controlled by means of an automatic tensioner. Therefore, no belt tension adjustments are required. However, belt and belt tensioner condition should be inspected at the specified intervals and replaced if required. Improper belt tension can cause belt slippage and failure. Low generator belt tension can cause battery failure. At the mileage indicated in the maintenance schedule, inspect belt and belt tensioner condition. Inspect belts for evidence of cuts, cracks, glazing, or frayed cords and replaced if there is indication of damage, which could result in belt failure. Also, check belt routing to make sure there is no interference between the belts and other engine components. See your authorized dealer for service. Spark Plugs Spark plugs must fire properly to assure engine performance and emission control. New plugs should be installed at the specified mileage. The entire set should be replaced if there is any malfunction due to a faulty spark plug. Malfunctioning spark plugs can damage the catalytic converter. For proper type of replacement spark plugs, refer to the "Vehicle Emission Control Information" label in the engine compartment.
