DESCRIPTION
Use the following repair procedure to minimize the need to replace the catalyst converter/exhaust pipe when removing oxygen sensors and/or air fuel ratio sensors.
REPAIR PROCEDURE
Oxygen Sensor Removal Procedure:
WARNING: To avoid personal injury, allow exhaust system to cool down before removing oxygen sensor.
NOTE: In some cases oxygen sensor and/or air fuel ratio sensor seizure will occur during this removal procedure. If seizure occurs, remove the converter or exhaust pipe from the vehicle and re-attempt removal with the assembly placed in a vise. This will maximize your positioning and ability to apply adequate torque to remove the sensor.
- If reusing oxygen sensor, mask it with masking tape (A) to prevent lubrication soaking.
- Spray CRC Freeze-Off (or equivalent) around the oxygen sensor flange (B).
CAUTION: Avoid excess spraying. Remaining flammable substance could catch fire.
- Allow lubricant to reach sensor threads for a minimum of 1 – 2 minutes.
NOTE: FOLLOW ALL PENETRANT MANUFACTURER INSTRUCTIONS LISTED ON THE PRODUCT LABEL.
- Turn 30 degrees counter-clockwise with SST (49 L018 001).
- Remove SST or Oxygen Sensor Socket and spray lubricant again in the same place.
- Allow lubricant to reach sensor threads for a minimum of 1 – 2 minutes.
- Use SST or Oxygen Sensor Socket to loosen sensor.
NOTE: If sensor begins to bind, it may be necessary to work the sensor in a tightening and loosening motion to slowly work the sensor out.
- Wipe off all excess lubricant.
- Clean O2 sensor threads in converter or pipe with SST J-43897-18.
NOTE: If the converter or exhaust pipe threads cannot be correctly cleaned on the vehicle, remove the converter or exhaust pipe from the vehicle to perform thread cleaning procedure. If the threads cannot be adequately cleaned to correctly install the sensor, then converter or exhaust pipe can be replaced. However, replaced catalytic converters are collected, the threads are cleaned and a new sensor is installed and torqued to spec. to confirm the converter replacement was necessary.
The claim is subject to debit if a new sensor can be installed and torqued to spec.
- Coat O2 sensor threads with “NEVER-SEEZ” (or equivalent) high temperature nickel based anti-seize grease.
WARNING: If reusing the oxygen sensor, completely remove the masking tape to prevent vehicle fire.
- Install O2 sensor and tighten to:
Tightening Torque: 29 – 49 Nm (22 – 36 ft. lbs.)
