CAUTION:
-
Always replace exhaust gaskets with new ones when reassembling.
-
With engine running, check all tube connections for exhaust gas leaks, and entire system for 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 or vibration.
-
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 new oxygen sensor, clean exhaust system threads using oxygen sensor thread cleaner Tool J-43897-18 or J-43897-12 and
approved anti-seize lubricant.
-
Do not overtorque the oxygen sensor. Doing so may cause damage to the oxygen sensor, resulting in the MIL coming on.
