Checking Exhaust SystemNJFE0010Check exhaust pipes, muffler and mounting for improper
attachment, leaks, cracks, damage, chafing or deterioration.
Removal and InstallationNJFE0005CAUTION:
+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 a new oxygen sensor, clean exhaust sys-
tem threads using oxygen sensor thread cleaner tool and
apply anti-seize lubricant.
+Do not overtorque the oxygen sensor. Doing so may
cause damage to the oxygen sensor, resuiting in the MIL
coming on.
+Be sure to use genuine exhaust system parts which are
designed especially for heat resistance, corrosion
resistance, and shape.
+Perform the operation with the exhaust system fully
cooled down because the system will be heated just after
the engine stops.
+Be careful not to cut your hand on the insulator edge.
