EXHAUST SYSTEM
[MR20DE]
G Perform the operation with the exhaust system fully cooled down because the system will be hot
just after the engine stops. A
G Be careful not to cut your hand on heat insulator edge.
1. Disconnect harness connector of heated oxygen sensor 2.
G Using Tool, remove heated oxygen sensor 2. EX
CAUTION:
Be careful not to damage heated oxygen sensor 2.

INSTALLATION
Installation is in the reverse order of removal.
CAUTION: E
G Always replace exhaust gaskets and seal bearings with new ones when installing.
G Discard any heated oxygen sensor 2 which has been dropped from a height of more than 0.5 m
(19.7 in) onto a hard surface such as a concrete floor; use a new one.
F
G Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated
oxygen sensor thread cleaner and apply anti-seize lubricant (commercial service tool).
G Do not over tighten heated oxygen sensor 2. Doing so may cause damage to the heated oxygen G
sensor 2, resulting in the "MIL" coming on.
G Remove deposits from the sealing surface of each connection. Connect them securely to avoid
exhaust leakage.
H
G Temporarily tighten nuts on the exhaust manifold side and bolts on the vehicle side. Check each
part for unusual interference, and then tighten them to the specified torque.
G When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
I
left directions.
Exhaust Manifold to Exhaust Front Tube
1. Securely insert seal bearing (2) into exhaust manifold (1) side in J
the direction shown.
G Exhaust front tube (5)
CAUTION: K
Be careful not to damage seal bearing surface when install-
ing.
