Catalytic Converter: Testing and Inspection
INSPECTION
Look at the stainless steel body of the converter, inspect for bulging or other distortion that could be a result of overheating. If the converter has a heat
shield attached make sure it is not bent or loose.
WARNING: UNLEADED FUEL MUST BE USED TO PREVENT BLOCKAGE OR CONTAMINATION TO THE CATALYST CORE.
If you suspect internal damage to the catalyst, tapping the bottom of the catalyst with a rubber mallet may indicate a damaged core.
CLEANING
Clean ends of pipes and muffler to assure a good seal at mating surfaces.
