    Default o2 sensors

    On a 2008 C6:

    1) how many O2 sensors are there &
    2) can someone tell me where they are?


    I need to make sure they are all nice and snug.

    There are four sensors.

    One upstream of each cat converter. And one just downstream of each cat.

    It's unlikely you need to tighten them, but you insist, you'll need an oxygen sensor socket and, if you remove them, you need a little bit of that special glass impregnated antiseize lubricant that is used on O2S threads.
