    O2 sensor.

    B2S1 = left (front) exhaust manifold collector
    B1S1 = right (rear) exhaust manifold, top center
    B1S2 = pre-cat
    B1S3 = after-cat (if no pre-cat sensor is fitted, then the after-cat becomes B1S2)

    B1S1 is absolute murder to change. Over the top of the engine using extensions and either a crow's foot or special O2 sensor socket. Good luck.

    Please go back to your original post in the Lounge and follow the advice for updating your login. Consider either subscribinbg your car to www.alldatadiy.com or obtaining a real GM service manual set from eBay or www.helminc.com . Read all the sticky posts at the top of the threads in each forum of interest. Study the entire Cadillac Technical Archive way up ^^^ in the top black bar. You have a LOT to learn about this car and its special needs.

    Submariner 408 ,Thank you for your advice ... So If I have special O2 sensor socket, and technical knowledge will be OK. B1S1 is on top of manifold in rear of the engine? I see that I have a lot of space to work...
