CAUTION:
I
Always replace exhaust gaskets with new ones when
reassembling. If gasket remains on flange surface, scrape
off completely as shown at left.
I
With engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.
I
Check to ensure that mounting brackets and mounting
insulators are installed properly and free from undue
stress. Improper installation could result in excessive
noise or vibration.
I
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.
I
Before installing a new oxygen sensor, clean exhaust sys-
tem threads using oxygen sensor thread cleaner tool,
J-43897-18 or J-43897-12, and apply anti-seize lubricant.
I
Do not overtorque the oxygen sensor. Doing so may
cause damage to the oxygen sensor, resuiting in the MIL
coming on.
