Important:A special anti-seize compound is used on
the oxygen sensor threads. This compound consists of
a liquid graphite and glass beads. The graphitewill burn
away, but the glass beadswill remain, making the sen-
sor easier to remove. New or serviced sensors will al-
ready have the compound applied to the threads. If a
sensor is removed from any engine and is to be rein-
stalled, the threads must have an anti-seize compound
applied before reinstallation.
4. Coat the threads of the oxygen sensor with an anti-
seize compound, if needed.
5. Installation should follow the removal procedure in
