Exhaust Manifold
●
If stud bolts were removed, install them and tighten to the specified torque.
●
Install exhaust manifold and tighten nuts in numerical order as
shown.
NOTE:
Tighten nuts No. 1 and 2 in two steps. The numerical order No. 7
and 8 shown second step.
Heated Oxygen Sensor
CAUTION:
●
Before installing a new air fuel ratio sensor 1 and heated oxygen sensor 2, clean exhaust system
threads using oxygen sensor thread cleaner and apply anti-seize lubricant.
●
Do not over torque air fuel ratio sensor 1 and heated oxygen sensor 2. Doing so may cause dam-
age to air fuel ratio sensor 1 and heated oxygen sensor 2, resulting in the “MIL” coming on.
