230 MAINTAINING YOUR VEHICLE 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 At the mileage indicated in the maintenance schedule, all belts should be checked for condition and proper tension. Improper belt tension can cause belt slippage and failure. Belts should be inspected for evidence of cuts, cracks, or glazing, and replaced if there is indication of damage which could result in belt failure. If adjustment is required, see your authorized dealer for service. Low generator belt tension can cause battery failure. A special tool is 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 proper engine performance and emission control. The plugs installed in your vehicle should operate satisfactorily in normal service for the mileage indicated in the Maintenance Chart. New plugs should be installed at this mileage. The entire set should be replaced if there is any malfunction due to a faulty spark plug. Check the Vehicle Emissions Control Information label for the proper type of spark plug for your vehicle. CAUTION! When replacing plugs, do not overtighten. You could damage them and cause them to leak. Ignition Cables Replace the ignition cables at the mileage interval shown in the maintenance charts. Engine Air Cleaner Filter Under normal driving conditions, replace the air filter at the intervals shown on Schedule "A". If, however, you drive the vehicle frequently under dusty or severe conditions, the filter element should be inspected periodically and replaced if necessary at the intervals shown on Schedule "B".
