5. Remove the left side downstream oxygen sensor from the catalytic converter.
6. Raise and support the vehicle. Refer to HOISTING, STANDARD PROCEDURE .
7. Remove the belly pan and the exhaust cross-under pipe from vehicle. Refer to PIPE, EXHAUST CROSSUNDER, REMOVAL AND INSTALLATION .
   NOTE: The lower bolts for the converter flange are used to hold a guide retainer plate. The retainer does not need to be removed. The catalytic converter is held in by the plate and upper bolts.
8. Remove the catalytic converter to exhaust manifold upper bolts.

3. Install the upper flange bolts and tighten to the proper torque specifications. Refer to TORQUE SPECIFICATIONS .
4. Install the exhaust cross-under pipe and belly pan. Refer to PIPE, EXHAUST CROSSUNDER, REMOVAL AND INSTALLATION .
5. Remove the support and lower the vehicle.
6. Install the left side downstream oxygen sensor and tighten to the proper torque specifications. Refer to TORQUE SPECIFICATIONS .
   NOTE: If reinstalling the original oxygen sensors, coat the sensor threads with an anti-seize compound such as Loctite 771- 64 or equivalent. New sensors have compound on the threads and do not require an additional coating. Do Not add any additional anti-seize compound to the threads of a new oxygen sensor.
