3.3 Oil Filter Adaptor
Remove

Disconnection of the battery affects
certain vehicle electronic systems, refer to
1.1 WARNING, CAUTION and NOTES before
disconnecting the battery.
1 Disconnect the battery negative terminal.
2 Disconnect the wiring harness connecto r from the oil pressure sender.

3 Remove the oil filter adaptor attaching bolts (2), four
places.
4 Remove the oil filter adaptor and discard the gasket (3).
5 Clean the surfaces of t he adaptor and cylinder block.

• Do not use a screwdriver or similar to
prise the oil filter adapter from the engine
as damage to the sealing surface may
occur.
• If required, use a rubber mallet to tap the
oil filter adapter to loosen the
components prior to separating.
Tapping should be done at bends,
corners or reinforced areas to prevent
distortion of parts.
Figure 6A1 – 27
Reinstall
Reinstallation of the oil filter adaptor is the reverse of the remo val procedure, noting the following:
1 A new gasket must be used.
2 Loosely install the oil filter adaptor attaching bolts, then tighten all fast eners to the correct torque specification.

3 Retract the throttle body wiring connector lock (3).
4 While pressing the connector latch in the direction of
the arrow (4), disconnect the throttle body wiring
connector.
5 Disconnect the throttle body connector wiring harness from its retaining clip (5).
6 Remove the main wiring harness retainer pin (6) from the intake manifold by pushing from the front to the
rear using a suitable piece of 5 mm steel rod (or an
Allen key).

The following precautions must be followed
when disconnecting the throttle body wiring
connector:
• Do not use any mechanical device such
as a screwdriver to disengage the
harness connector (1) from the throttle
body (2).
• When retracting the throttle wiring
connector lock (3), take care not to
disengage the lock from the connector.
• Do not pull on the connector wires.
• Take care not to break the barbed
harness retainer pin (6) while removing
the harness retainer from the intake
manifold.
• Should the pin be broken, then it is
vital that a new harness retainer is
fitted to the wiring harness shield. If
not, the harness will foul the engine
drive belt.
