How to replace the Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 on Cadillac Escalade EXT?

Organize this installation by first properly supporting the vehicle using a suitable height. Prior to moving forward begin by removing the front propeller shaft from the front Differential if needed. The connector position assurance (CPA) retainer should be detached then you can remove the ho2s electrical connector from its fuel line clip. Vehicles with either a 4.8l or 5.3l engine require disconnecting the ho2s electrical connector. Both 6.0l engine owners and 4.8l and 5.3l engine owners should repeat these same steps. Follow the ho2s removal process carefully while avoiding strong insertion of force. Use anti-seize compound gm p/n 12377953 or an equivalent to coat ho2s threads when using previously employed sensors because a special anti-seize compound containing liquid graphite combined with glass beads helps achieve improved ho2s thread removal. Secure the ho2s with a torque of 42 n.m (31 lb ft). The installation of the ho2s electrical connector requires connection of the device for both 6.0l engines and 4.8l or 5.3l motors. Before lowering the vehicle, reconnect ho2s electrical connector to fuel line clip and discontinue cpa retainer while installing front propeller shaft to front Differential if required.

Follow the ho2s removal process carefully while avoiding strong insertion of force. Use anti-seize compound gm p/n 12377953 or an equivalent to coat ho2s threads when using previously employed sensors because a special anti-seize compound containing liquid graphite combined with glass beads helps achieve improved ho2s thread removal. Secure the ho2s with a torque of 42 n.m (31 lb ft). The installation of the ho2s electrical connector requires connection of the device for both 6.0l engines and 4.8l or 5.3l motors. Before lowering the vehicle, reconnect ho2s electrical connector to fuel line clip and discontinue cpa retainer while installing front propeller shaft to front Differential if required.
