 Install exhaust manifold and tighten mounting nuts in numerical
order as shown in the figure.
NOTE:
Tighten mounting nuts No. 1 to 4 in two steps. The numerical order
No. 9 to 12 shown second steps.
Air Fuel Ratio Sensor and Heated Oxygen Sensor
 Install air fuel ratio sensors and heated oxygen sensors in the original position.
 Install referring the following if the installation positions cannot be identified.
CAUTION:
 Before installing a new air fuel ratio sensor and heated oxy-
gen sensor, clean exhaust system threads using oxygen sen-
sor thread cleaner (commercial service tool: J-43897-18 or J-
43897-12), and apply anti-seize lubricant (commercial service
tool).
 Do not over torque air fuel ra tio sensor and heated oxygen sensor. Doing so may cause damage to
the heated oxygen sensor, r esulting in “MIL” coming on.
