REMOVAL & INSTALLATION
The oxygen sensor is mounted in the exhaust manifold.
- Disconnect the engine harness connector from the sensor.
Do not pull on the sensor wire.
- Remove the sensor using Tool C-4589 on the carbureted engine and Tool C-4907 or their equivalents, for the fuel injected and turbo engines.
- After the sensor is removed clean the exhaust manifold threads with an 0.7 in. x 0.06 in. x 6E (18mm x 1.5mm x 6E) tap. If the old sensor is to be reinstalled, the sensor threads must be coated with an anti seize compound such as Loctite® 771-64 or equivalent on the threads. New sensors are packaged with compound on the threads and no additional compound is required.
- Tighten the sensor to 20 ft. lbs. (27 Nm).
