REMOVAL SERVICE POINT



<<A>> LINEAR AIR-FUEL RATIO SENSOR REMOVAL



Use special tool oxygen sensor wrench (MB991953) to remove the linear air-fuel ratio sensor.

INSTALLATION SERVICE POINTS



>>A<< EXHAUST MANIFOLD/EXHAUST MANIFOLD WASHER/EXHAUST MANIFOLD NUT INSTALLATION


1.Install the exhaust manifold and the exhaust manifold washer.
2.Temporarily tighten the exhaust manifold nut.

3.Tighten the exhaust manifold nut with the specified torque in the order of number shown in the figure.
Tightening torque: 49 ± 5 N·m

>>B<< LINEAR AIR-FUEL RATIO SENSOR INSTALLATION



In the same manner as removal, use special tool oxygen sensor wrench (MB991953) to tighten the linear air-fuel ratio sensor to the specified torque.
Tightening torque: 44 ± 5 N·m

>>C<< O-RING/CRANK ANGLE SENSOR INSTALLATION


caution
  • Do not apply a force such as torsion or twist to the O-ring during assembly of the sensor.
  • Assemble the sensor, taking care not to give a shock to it.
  • Do not use a sensor that has fallen down.

1.Apply liquid gasket to the illustrated area of the crank angle sensor.
Specified sealant:
    ThreeBond 1207D or equivalent
2.Tighten the crank angle sensor installation bolt to the specified torque.
Tightening torque: 11 ± 1 N·m

>>D<< CRANK ANGLE SENSOR COVER/EXHAUST MANIFOLD BRACKET INSTALLATION


caution The exhaust manifold gasket, washers and nuts must not be reused.
1.After temporarily tightening the exhaust manifold bracket with the installation bolts, check the exhaust manifold fastens securely to the cylinder block.

2.Tighten the cylinder block side bolt to the specified tightening torque.
Tightening torque: 41 ± 10 N·m
3.Tighten the exhaust manifold side bolt to the specified tightening torque.
Tightening torque: 56 ± 8 N·m
4.Tighten the crank angle sensor cover bolt to the specified tightening torque.
Tightening torque: 11 ± 1 N·m
