INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
• Always replace seal bearings with new ones when reassembling.
• Discard any heated oxygen sensor 2 which has been dropped onto a hard surface such as a con-
crete floor; use a new one.
• Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxy-
gen sensor thread cleaner and apply anti-seize lubricant (commercial service tool).
• Never over torque heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sen-
sor 2, resulting in the “MI” coming on.
• Remove deposits from the sealing surface of each connection. Connect them securely to avoid gas
leakage.
• When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
• Temporarily tighten mounting nuts and bolts. Check each part for unusual interference, and then
tighten them to the specified torque.

• Ensure that mounting brackets and mounting rubbers are installed properly and free from undue stress.
Improper installation could result in excessive noise and vibration.

CAUTION:
• Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.
• Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.
• Be careful not to cut your hand on the heat insulator edge.
