Catalytic Converter and Intermediate Pipe Heat Shields

NOTICE: Inspect the shields for cracks, tears, and missing fasteners. All shields must be firmly attached. Shields must be installed whenever removed for exhaust system or body repairs, etc. to prevent vehicle panel and fuel tank damage.


Removal

CAUTION:
^ MAKE SURE VEHICLE IS PROPERLY SUPPORTED AND SQUARELY POSITIONED PRIOR TO LIFTING. TO HELP AVOID PERSONAL INJURY WHEN A VEHICLE IS ON A HOIST, PROVIDE ADDITIONAL SUPPORT FOR THE VEHICLE ON THE OPPOSITE END FROM WHICH COMPONENTS ARE BEING REMOVED. MAKE SURE HOIST DOES NOT CONTACT FUEL OR BRAKE LINES.
^ HEAVY WORK GLOVES AND EYE PROTECTION MUST BE WORN WHEN MODIFYING THE EXHAUST HEAT SHIELD, AND WHEN REMOVING AND INSTALLING THE INTERMEDIATE EXHAUST PIPE ISOLATOR. THE EXHAUST HEAT SHIELD EDGES ARE EXTREMELY SHARP AND CONTACT WITH THE EDGES COULD CAUSE PERSONAL INJURY.

2. Remove the (3) intermediate pipe-to-catalytic converter nuts (13 mm hex) at converter and discard gasket.
3. Remove intermediate pipe isolator and lower exhaust system to the fullest extent.

NOTICE: Use extreme care when grinding off the rivet heads. Always install all the shields to insure against panel and fuel tank damage.
