• If the HO2S has been removed, but not replaced, anti-seize compound must be applied to the threads prior to
installation. New HO2S will already have the anti-seize compound applied.
• For vehicles with the six wire HO2S sensor, under no
circumstances should the protective cover (1) be
removed, or the gortex filter (2) be covered and / or
sealed.
Figure 6C1-3 – 42

Figure 6C1-3 – 46
Reinstall
Reinstallation of the heated oxygen sensor (HO2S) is the reverse of the removal procedure, noting the following:

A special anti-seize compound is used on the
HO2S threads. A new HO2S will already have
the anti-seize compound applied to the
threads.
If a HO2S has been removed, but not replaced,
then anti-seize compound must be applied to
the threads prior to installation.
1 Coat the cleaned threads of the sensor with anti-seize compound.
2 Tighten the HO2S to the correct torque specification.
Heated oxygen sensor
torque specification .................................40.0 – 50.0 Nm
3 Road test the vehicle and check for correct operation, taking particular note that no exhaust leakage is evident.

6 Remove the bolt (1) attaching the knock sensor (2) to
the engine block and remove the knock sensor.
Figure 6C1-3 – 57
Reinstall
Reinstallation of the knock sensor is the reverse of the removal procedure, noting the following:
1 Ensure the knock sensor mounting surface is flat and free of any dirt, oxidisation, etc.

Ensure the knock sensor is fully seated and
correctly aligned before tightening the
attaching bolt.
Do not over-tighten the attaching bolt as
incorrect operation of the knock sensor may
result.
2 Reinstall the knock sensor and bolt (1). Align the knock sensor so that it is parallel to the engine oil pan
mounting surface (2), ± 3° (3).
3 Tighten the knock sensor bolt to the correct torque specification.
Knock sensor attaching bolt
torque specification .................................21.0 – 25.0 Nm
4 Road test the vehicle and check for correct operation, taking particular note that no exhaust leaks are
evident.

9 Install the seal protector, Tool No. AU583-1 (1) into
one of the two plastic seal installers, Tool No.
AU583-2 (2).
NOTE
Two plastic seal installers are required because
of the restricted space between the end of the
manual shaft and the floor pan.
10 Lubricate the lip of a new seal (3) with clean automatic transmission fluid and install it over the seal protector
sleeve, with the steel casing facing the installer tool.
11 Install the seal protector with the new seal and installer tool over the manual shaft (4) and up to the
transmission case.

If the seal protector sleeve jams on the
manual shaft, the flats on the shaft locating
the selector lever will be burred. Use a fine
file to remove any burrs and then proceed.
12 Fit the second plastic seal installer over the manual shaft until it seats against the first installer.
13 Install the manual shaft linkage attaching nut (5) and tighten it to drive the seal in position into the
transmission case.
14 Remove the seal installer and protector tools from the manual shaft.
Figure 7C4 – 18
15 Reinstall the neutral start and back-up lamp switch, refer to 3.4 Neutral Start and Back-up Lamp Switch.
