4. Install front exhaust pipe to three way catalytic converter gasket and fasteners.

NOTE: Always use a nickel-based anti-seize compound (Saturn P/N 21485279 or equivalent) on the threads of the oxygen sensor. Never use silicone products; silicone products will damage the oxygen sensor.
- Torque: 25 NM (19 ft. lbs)

Rear Oxygen Sensor:

5. Install rear heated oxygen sensor using Saturn tool SA9603E.
- Torque: 45 NM (33 ft. lbs)




NOTE: Make sure to center marker tape with the edge of the trough. The marker tape must be centered with the edge of the trough to ensure enough slack in the harness.
