Reconditioning the exhaust system threads
before installing a new heated oxygen sensor
(Use with anti-seize lubricant shown below.)

Checking Exhaust System

EBS004VQ

Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.

Removal and Installation

EBS001JQ

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 the engine stops.

●

Be careful not to cut your hand on the insulator edge.

EX-5, "Removal and Installation"

Disconnect each joint and mounting.

INSTALLATION

Install in the reverse order of removal.

CAUTION:

●

Always replace exhaust gaskets with new ones when reassembling.

●

Discard any heated oxygen sensor 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.

●

Before installing a new heated oxygen sensor, clean exhaust system threads using heated oxygen
sensor thread cleaner tool, J-43897-18 or J-43897-12, and apply anti-seize lubricant.

●

Do not over torque the heated oxygen sensor. Doing so may cause damage to the heated oxygen
sensor, resulting in the MIL coming on.

●

If the insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insu-
lator, remove them.

●

When installing the insulator avoid large gaps or interference between the insulator and each
exhaust pipe.

●

Remove deposits and left over gasket material from the sealing surface of each connection. Con-
nect them securely to avoid gas leakage.

●

Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for abnormal interference, and then tighten them to the specified torque.

●

When installing each clamp, align the protrusion on the insulator with the clamp hole.

●

When installing each mounting rubber, avoid twisting or abnormal extension in up/down and right/
left directions.

●

Install mounting rubbers on rear main muffler as shown.

INSPECTION AFTER INSTALLATION

●

With the engine running, check exhaust tube joints for gas leakage and unusual noises.

●

Check to ensure that mounting brackets and mounting insulators are installed properly and free from
undue stress. Improper installation could result in excessive noise and vibration.
