Catalytic Converter: Description and Operation

There is no regularly scheduled maintenance on any Chrysler catalytic converter. Excessive heat may cause bulging or other distortion, but excessive heat will not be the fault of the converter. A fuel system or ignition system malfunction that permits unburned fuel to enter the converter will usually cause overheating. If a converter is heat damaged, correct the cause of the damage at the same time the converter is replaced. The entire converter must be replaced. Inspect all other components of the exhaust system for heat damage.

CAUTION:
- Due to exterior physical similarities of some catalytic converters with pipe assemblies, extreme care should be taken with replacement parts. There is internal converter differences required in some parts of the country (particularly California vehicles).

- Unleaded gasoline must be used to avoid damage to the catalyst core.
