This video is about catalytic converters and what causes these sophisticated components to fail.

Any number of problems can damage a converter. And these issues must be corrected before installing a new one.

There are four primary types of converter failures: poisoning, coated or oil-fouled substrate, overheated or melted, and structural damage.

Learn more about these four types of failures and the common causes for these failures by watching this video.

Bottom line, these components don't fail on their own -- an outside issue, often related to the ignition, fuel system, engine or engine controls, has caused the failure. And you've got to fix the root cause if you want your replacement converter to last.
