How to maintain a catalytic converter?

The catalytic converter is an emission control device that reduces hydrocarbon and carbon monoxide pollutants in the exhaust system. It contains beads coated with platinum and palladium, and it is important to use unleaded gasoline to prevent lead contamination and corrosion. While periodic maintenance is not required, it is advisable to inspect the converter during other service. If the converter is ineffective, it can be replaced or the coated beads can be drained and replaced. Caution should be exercised when working on the converter due to its high temperatures. The removal process involves disconnecting the converter from the exhaust pipes and gently separating the flanges. Installation is the reverse of removal, using new nuts and bolts. There are two types of catalytic converters, and the monolith converter must be replaced entirely if it fails. The catalyst in bead-type converters can be changed by draining and filling the beads. This process is best done by a dealer with specialized equipment. To fill the converter with new beads, it should be raised at an angle and tapped lightly while pouring in the beads. A special service fill plug is required for installation. Once installed, the engine should be started and checked for leaks.
