Question about 2000 Cadillac Escalade
To remove the O2 sensor you will need an O2 sensor socket that you can buy at most auto part stores, or you can dis-connect the wire connector for that O2 sensor, and then slip the wire connector from the O2 sensor through a 7/8 inch box end wrench and then slide the wrench up to the O2 sensor and then remove the O2 sensor. Use plenty of W-D40 to soak the base of the O2 sensor before removing it, and if the wire connector does not fit through the box end of the wrench then cut the wire connector off from the O2 sensor, and you will only need the open end of the wrench to install the O2 sensor, and only tighten the O2 sensor up until you feel the the sealing rings crush down, and do not over-tighten the O2 sensor because they are not supposed to be torqued down.
