34 Disconnect the throttle cable from the
operating lever and bracket.
35 Disconnect the right-hand exhaust
downpipe from the manifold then remove the
starter motor, the oil filter, and disconnect the
left-hand exhaust downpipe, in that order.
Refer to Part A, Section 8, paragraphs 1 to 8
of this Chapter.
Cylinder head bolts on the V6 engine may
be conventional (hexagon-headed) or Torx
type. The appropriate Torx key will be needed
to deal with the latter.
Before dismantling the engine into its main
components, the following ancillaries can be
removed. The actual items removed, and the
sequence of removal, will depend on the work
to be done.
Distributor and bracket
Spark plugs
Inlet manifold and associated items
Exhaust manifolds
Clutch
Alternator and bracket
Oil pressure switch (see illustration)
Temperature gauge sender
Engine bearer arms
Dipstick
If an oil cooler is fitted between the oil filter
and the block, remove it by disconnecting the
coolant hoses and unscrewing the central
sleeve. The cooler and seal can now be
removed. If the threaded bush is removed
from the block (it may come out with the
sleeve) it must be renewed.
The procedure is described for the engine in
the vehicle. With the engine removed, the
preliminary steps can be ignored.
2.8 litre engine
1 Disconnect the battery negative lead.
2 Remove the inlet manifold and associated
components.
3 Unbolt the power steering pump, remove
the drivebelts and move the pump aside.
Support it by wiring it to adjacent
components.
4 Remove the alternator and its bracket.
5 Remove the three bolts which secure each
rocker shaft. Remove the shafts and
pushrods, keeping them in order so that they
can be refitted in the same locations.
6 Unbolt the exhaust pipes from the
manifolds.
7 Remove the spark plugs.
8 Slacken the cylinder head bolts half a turn at
a time, following the reverse sequence to that
used when tightening (see illustration 38.5).
Remove the bolts.
9 Remove the cylinder heads. If they are
stuck, try to rock them free, or tap them with a
soft-faced hammer. Do not hit them directly
with a metal hammer, and do not lever in
between the joint faces.
10 Recover the head gaskets.
2.4 & 2.9 litre engines
11 Disconnect the battery and drain the
cooling system.
12 Disconnect the radiator top hose and the
heater hose from the thermostat housing.
13 Disconnect the air hoses from the throttle
valve housing (see illustration).
14 Detach the two wiring plugs from the
airflow sensors (see illustrations).
15 Pull the breather hose from the oil filler cap
(see illustration).
16 Unclip the air cleaner cover and remove it
together with the airflow sensors and air hoses.
17 Disconnect the hoses from the coolant
expansion tank.
18 Disconnect the wiring from the following
components:
a)
Alternator (right-hand cylinder head
removal only).
b) Coolant temperature sensors (see
illustration).
c) Idle speed control valve (see illustration).
d) Throttle valve potentiometer.
e) The fuel-injector wiring loom.
