Before installing the sensor threads require an application of anti-seize compound GM P/N 5613695 consisting of liquid graphite and glass beads based on necessity. Use the Oxygen Sensor Wrench (J 39194-B) to install the HO2S and torque it to 42 N.m (31 lb ft). Lower down the vehicle before connecting the HO2S harness connector.
Q: How to replace the Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1 on Cadillac CTS?
A: In order to replace the Heated Oxygen Sensor (HO2S) Bank 2 Sensor 1, first remove the left side air inlet panel. Make sure the HO2S and the O2S are treated gently while maintaining the in-line electric connector and the louvered end clean of grease, dirt, contaminations, and never use in cleaning solvents.
