How to replace the Heated Oxygen Sensor 2 on 2007 Chevrolet Cobalt?

Vehicle heightening and suitable support are necessary before starting to replace the heated Oxygen Sensor 2. Withe the wheel drive shaft heat shield off the technician will need to note the path of the heated Oxygen Sensor (HO2S) electrical cabling. To access the ho2s electrical connector in the engine compartment first bend carefully the edge of the channel on the left-hand side of the Exhaust Heat Shield outboard. This releases the ho2s electrical harness for removal. First remove the ho2s using the Oxygen Sensor wrench (J 39194-C) and then lower the ho2s electrical harness away from the vehicle underbody. Before installing the original ho2s item coat its threads in saturn p/n 24185279 or equivalent anti-seize compound. To complete ho2s installation please use the Oxygen Sensor wrench (J 39194-C) for tightening the sensor to 41 n.m (30 lb ft) on the pipe. Reinstall the ho2s electrical harness following its original placement while avoiding wire damage to the Exhaust Heat Shield's channel. The Exhaust Heat Shield channel edge must be bent on its lh side inboard to hold the ho2s electrical harness into place before connecting the ho2s electrical connector. For the last step of the procedure reinstall the wheel drive shaft heat shield before lowering the vehicle.
