CATALYTIC CONVERTER
Inspection

1. Check the catalytic converter for deterioration or clogging.
2. Check the insulation covers welded onto the catalytic converter for damage.

Note: If the insulation cover is touching the catalytic converter housing, excessive heat at the floor will occur.

3. Start the engine and check for exhaust gas leakage from each exhaust system components.
4. If leakage is found, repair or replace as necessary.
