1. Remove the eighteen bolt s which secure the oil pan
to the oil pan body.
2. Remove the oil pan.
3. Remove the gasket from the oil pan body assembly.
11. Remove the oil pan body a ssembly. Refer to Operation

5.
Install the front cros smember. Refer to Operat

detailed in Operation 12.65.01.
9. Install the twin fan and motor assembly. Refer to Operation
26.25.12.
10. NOTE: When the engine is star ted from cold and run for a
short period only, before being swit ched off, a quantity of oil will
be 'hung up' within the engine because it is not up to operating
temperature.
Should the oil level subsequently be topped-up, the level could
become too high, causing oil burning.
Typically, 0.875 L is hung up.
Refill the engine with the correct specification engine oil.
11. Connect the battery and in stall the battery cover.
Refe
r to the Battery Reconnection Procedure 86.15.15.
12. Check the oil level and start th e engine. Check for leaks and
that the engine runs correctly.
13. Install the engine compartmen t cover. Refer to operation
76.16.01.
14. Remove the paintwork protection sheets and close the engine
compartment cover.

4. Remove the Timing Co ver. Refer to Operation 12.65.01 in this
Section.
5. Remove the VVT bush carrier from the A-Bank.
1. Remove the three bolts which secure the carrier to the cylinder block.

2. Fi
t the retaining / pivot bolt and tighten it to 12 - 16
Nm.

5. Refi
t the primary chain tensione
r assembly. Refer to Operation
12.65.55 in this Section.
U s
e a wedge 303 - 533 (or two if required) between the
primary chain tensioner and te nsioner blade, to take up
the slack in the chain.

6. Tigh te
n the exhaust camshaft
sprocket securing bolt.
1. Fit the chain tensioner tool 303 - 532 to the sprocket holes.
1. Apply force to the to
ol in
an anti-clockwise direction
to tension the chain on its drive side.
2 .
Whilst applying the opposing force to the sprocket
and chain, tighten the sprock et securing bolt to 115 -
