MAINTAINING YOUR VEHICLE 331 Disposing Of Used Engine Oil And Filter Care should be taken in disposing of the used engine fluids from your vehicle. Used fluids, indiscriminately discarded, can present a problem to the environment. Contact your local dealer, service station, or governmental agency for advice on recycling programs and where used fluids and filters can be safely discarded in your area. Drive Belt Inspection Check the belt for intersecting cracks. • Transverse (across the belt width) cracks are acceptable. • Longitudinal (direction of belt length) cracks that intersect with transverse cracks are NOT acceptable. Replace the belt if it has unacceptable cracks, is frayed or has pieces of material missing. The engine speed sensor, located near the damper, should be inspected for damage if a belt is frayed. Engine Air Cleaner Filter CAUTION! All air entering the engine intake must be filtered. The abrasive particles in unfiltered air will cause rapid wear to engine components. 7 The air filter housing on your Diesel Ram is equipped with a Filter Minder™. This is an air flow restriction gauge that will indicate when the filter element needs to be replaced.
