Front Heated Oxygen Sensor (HO2S1) Removal and Installation: Installation

CAUTION: A special anti-seize compound is used on the heated oxygen sensor threads. This compound consists of a liquid graphite and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or serviced sensors will already have the compound applied to the threads. If a sensor is removed from any engine and is to be reinstalled, the threads must have an anti-seize compound applied before reinstallation.

Coat the threads of the HO2S1 with an anti-seize compound, if needed.
Install the HO2S1 into the exhaust manifold.
Tighten:

Tighten the heated oxygen sensor to 42 N.m (31 lb-ft).
Connect the HO2S1 connector.
