Catalytic Converter: Service and Repair

CATALYTIC CONVERTER

CAUTION: Due to exterior physical similarities of some catalytic converters with pipe assemblies, extreme care should be taken with replacement parts. There are internal converter differences required in some parts of the country (particularly vehicles built for States with strict emission requirements) and between model years.

REMOVAL

WARNING: THE NORMAL OPERATING TEMPERATURE OF THE EXHAUST SYSTEM IS VERY HIGH. THEREFORE, NEVER WORK AROUND OR 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.

1. Disconnect negative battery cable at remote jumper terminal located at right strut tower.
2. Raise vehicle on hoist.
3. Remove exhaust system.
4. Remove the torca clamp.
5. Separate the catalytic converter from the muffler.
6. Clean ends of the catalytic converter and muffler to assure mating of all parts. Discard broken or worn insulators, rusted clamps, supports and attaching parts. When replacement is required on any component of the exhaust system, it is important that original equipment parts (or equivalent) be used.

INSTALLATION
1. Position torca band clamp on the catalytic converter.
2. Install the muffler into the catalytic converter until guide pin seats in slot on muffler.
3. Tighten torca clamp to 54 Nm (480 inch lbs.).
4. Install exhaust system.
