Catalytic Converter: Testing and Inspection
INSPECTION
WARNING: THE NORMAL OPERATING TEMPERATURE OF THE EXHAUST SYSTEM IS VERY HIGH. THEREFORE, NEVER
ATTEMPT TO SERVICE ANY PART OF THE EXHAUST SYSTEM UNTIL IT IS COOLED. SPECIAL CARE SHOULD BE
TAKEN WHEN WORKING NEAR THE CATALYTIC CONVERTER. THE TEMPERATURE OF THE CONVERTER RISES
TO A HIGH LEVEL AFTER A SHORT PERIOD OF ENGINE OPERATION TIME.
Check catalytic converter for a flow restriction.
Visually inspect the catalytic converter element by using a borescope or equivalent. Remove oxygen sensor(s) and insert borescope. If borescope is
not available, remove converter and inspect element using a flashlight. Inspect element for cracked or melted substrate.
NOTE: Before replacing a catalytic converter, determine the root cause of failure. Most catalytic converter failures are caused by air, fuel or ignition
problems.
