Chrysler Neon 1995-1999 Repair Guide

Timing Belt



All engines covered by this guide utilize timing belts to drive the camshaft from the crankshaft's turning motion and to maintain proper valve timing. Some manufacturer's schedule periodic timing belt replacement to assure optimum engine performance, to make sure the motorist is never stranded should the belt break (as the engine will stop instantly) and for some (manufacturer's with interference motors) to prevent the possibility of severe internal engine damage should the belt break.

Because the engines are listed as interference motors (listed by the manufacturer as a motor whose valves might contact the pistons if the camshaft was rotated separately from the crankshaft), Chrysler corporation recommends changing the timing belt at 105,000 miles (168,000km) for vehicles operated under normal service conditions or 102,000 miles (163,000km) for vehicles operated under severe conditions.

You would be wise to check the belt periodically to make sure it has not become damaged or worn. Generally speaking, a severely worn belt may cause engine performance to drop dramatically, but a damaged belt (which could give out suddenly) may not give as much warning. In general, any time the engine timing cover(s) is(are) removed you should inspect the belt for premature parting, severe cracks or missing teeth.
