Just kidding[8D].

Tell us whether your 850 is turbo or NA. Turbo should have 2 sensors; one in front of the cat converter and the other in the aft. You would know when you see it (them); they are attached onto the exhaust pipe and have electrical wires attached. It is usually best to use O2 sensor socket, which is a 6-point deep well socket used for proper removal of the O2 sensors. If open-end or 12-point socket is used, the hex portion of the sensor may strip.

Spray plenty of PB Blaster a few hours before attempting to remove. Disconnect the electrical connector then loosen the sensor and remove. Make sure you do all these with the engine cold and the ignition switch off of course.

Haynes manual may have the procedure, or other members would be able to give you more precise instruction. I would go with direct-fit OEM Bosch sensor and would stay away from universal type, even if it's Bosch.

Good luck,
