Caution: Prolonged operation of a misfiring or flooded engine may cause the catalytic converter to overheat. Damage to the catalyst, the operating vehicle, or personal injury may result.
Notice: When jacking or lifting the vehicle from the frame side rails, be certain that the lift pads do not contact the catalytic converter. This may damage the converter.
Notice: The catalytic converters require the use of unleaded fuel only. Using leaded fuel will damage the catalytic converters and other emission system components.
The catalytic converter is an emission control devise. The catalytic converter is added to the exhaust system on unleaded fuel vehicles to reduce pollutants from the exhaust gas stream. The catalyst in the monolith converter in not serviceable.
The three-way catalytic converter burns three types of exhaust gases:
• | Carbon monoxide (CO) |
• | Hydrocarbons (HC) |
• | Oxides of nitrogen (NOx) |
The oxidation catalytic converter burns the same gases, but uses an air pump/smog pump to force added oxygen into the catalytic converter. The additional oxygen forces the converter to run hotter and to burn exhaust gases more effectively.
A single bed ceramic monolith style brick catalytic converter is used in combination with two types of catalyst
• | Oxidation catalyst |
• | Three-way (reduction/oxidation) catalyst |
The catalysts have coatings that contain platinum and palladium. These coatings burn the unwanted exhaust emissions.
