All this work is done from under the car. There are two sensors on the S70. One is called the upstream( located higher up on the exhaust manifold) and the other would be the downstream. They are located on the exhaust pipe prior to the cat. converter. Unscrew the sensor (need to borrow a special tool) and follow the wire up around the engine to a small connector. Be sure to use anti-seize grease around the threads of the new O2 sensor(s). rcal13a@Yahoo.com
