Catalytic Converter: Adjustments

EXHAUST SYSTEM ALIGNMENT INSPECTION
A misaligned exhaust system is usually indicated by vibration, grounding, rattling or binding of system components. Often the associated noise is hard to distinguish from other chassis noises. Look for broken or loose clamps and brackets. Replace or tighten as necessary. It is important that exhaust clearances and alignment be maintained.

EXHAUST SYSTEM ALIGNMENT PROCEDURES
1. Loosen the retaining hardware, flanges and the pipe support brackets.
2. Align the exhaust system, beginning at the front of the vehicle to establish maximum clearance.
3. Tighten the flange nuts and the exhaust manifold nuts evenly and alternately to 34-46 Nm (26-33 lb ft).
4. Tighten all retainers.

NOTE: Muffler, Three Way Catalytic (TWC) converter, Y pipe and exhaust hanger insulators should be replaced if they are worn or become badly corroded. Do not attempt to service these parts.

5. Start the engine and check the exhaust system for leaks.
