Removal Procedure
Caution: Refer to Exhaust Service Caution in Service Precautions.
Caution: Refer to Protective Goggles and Gloves Caution in Service Precautions.
1. Disconnect the Heated Oxygen Sensor (H02S) at the sensor pigtail.
Notice: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column or
intermediate shaft from the steering gear. Failure to do so will cause the coil assembly in the steering column to become uncentered which will cause
damage to the coil assembly.
2. Lock the steering column by installing the J 42640 into the underside of the steering column.
3. Raise and support the vehicle.
4. Remove the rear exhaust manifold pipe.
5. Remove the 2 nuts (2) attaching the secondary AIR tube (1) to the exhaust manifold (3).
6. Remove the secondary AIR tube (1) and the gasket from the exhaust manifold (3). Do not reuse the gasket.
