The catalytic converter reduces hydrocarbon and carbon monoxide pollutants in exhaust gases. It should be inspected for damage, cracks, and missing fasteners. When replacing, the exhaust system should be cool and new gaskets should be used. Penetrating oil should be applied to the clamp bolts and the nuts should be tightened to the specified torque. After installation, the engine should be started and checked for exhaust leaks.

Due to a Federal warranty covering emissions-related parts like the catalytic converter, it's advised to consult a dealer before replacing it yourself. The converter, an emission control device, comes in two types: the oxidation catalyst and the three-way catalyst. If you suspect malfunction, take it to a dealer or authorized facility for diagnosis. Check the converter for leaks, corrosion, or dents when servicing under body parts. If damaged, replace it. Use a vacuum gauge to diagnose plugged converters by checking for blocked exhaust. If pressure doesn't significantly increase, the exhaust system or converter may be blocked.

If component replacement is necessary, it is important to wait until the complete exhaust system is cool before attempting to remove the catalytic converter. The vehicle should be raised and securely supported on jackstands, and penetrating oil should be applied to the clamp bolts. After several minutes, the bolts and rubber hangers can be removed, and the converter can be separated from the exhaust pipe. Any old gaskets stuck to the pipes should be removed. During installation, new exhaust pipe gaskets should be used, and the clamp nuts should be tightened to the specified torque. Finally, the engine should be started and carefully checked for exhaust leaks.

A catalytic converter is an emission control device that reduces pollutants in the exhaust gas stream. There are two types of converters: the conventional oxidation catalyst and the three-way catalyst.
