Oxygen Sensor Replacement: Removal
- On all 1979 models and 1980 models with 4-cylinder engine, remove air cleaner and hot air pipe from exhaust shroud. On 1980 models with V6 engine, raise vehicle on hoist.
- Disconnect electrical lead from sensor and spray sensor threads with heat valve lubricant. Allow to soak a few minutes, then carefully back out oxygen sensor (care is required to avoid damaging threads in exhaust pipe).
