Catalytic Converter: Description and Operation

WARNING: Prolonged operation with a misfiring or flooded engine may cause the TWC to overheat. This could cause damage either to the catalyst itself or the operating vehicle anal possible personal injury.

CAUTION: When jacking or lifting the vehicle from frame side rails, be certain that the lift pads do not contact the TWC; damage to the converter may result.

DESCRIPTION
The TWC is an emission control device added to the exhaust system on gasoline engines to reduce pollutants from the exhaust gas stream.

CAUTION: The TWC requires the use of unleaded fuel only. Using leaded fuels may cause damage to the catalyst.

SERVICEABILITY
The catalyst is not serviceable; the TWC is serviced as part of the front pipe/TWC assembly.
