For 1990-2009 cars

Caution: 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 and possible personal injury.

Notice: When jacking or lifting the vehicle from frame side rails, be certain that the lift pads do not contact the TWC; damage may result. Refer to General Information for proper vehicle jacking and lifting procedures.

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

Notice: The TWC requires the use of unleaded fuel only, or damage to the catalyst may result.

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