16.36a Release breather hose
(arrowed) . . .
release it from the manifold (see
illustrations).
37 Disconnect the ECU vacuum pipe from
the manifold.
38 Loosen the retaining clip and disconnect
the fuel return hose from the fuel rail, covering
the open connections to prevent any ingress
of dirt (see illustration).
39 Disconnect the coolant system expansion
tank hose from the inlet manifold.
40 Release the fuel return hose from its
retaining clips.
41 Disconnect the injector harness and air
temperature sensor multiplugs.
42 Remove the two bolts which secure the
fuel feed pipe to the fuel rail and release the
pipe from the rail. Discard the O-ring and
cover the open connections to prevent any
ingress of dirt.
43 Working from the centre of the manifold
outwards, progressively loosen the manifold
securing nuts and bolts. Remove the
manifold, discarding the gasket.
Refitting
44 Refitting is the reverse of the removal
procedure, noting the following:
a) Thoroughly clean all component parts,
paying particular attention to the mating
surfaces.
b) Ensure that a metal insert is located in
each manifold stud or bolt hole.
c) Always fit a new manifold gasket (see
illustration).
d) Working in the sequence shown (see
illustration), tighten the manifold

e) Tighten all disturbed fasteners to their
specified torque wrench settings (where
given).
f) Fit new O-rings, lubricating them with
silicone grease.
g) Remove all masking materials.
h) Ensure all hose connections are securely
remade.
i) Refill the cooling system and check the
coolant level, then wash off any spilt
coolant.

Removal
1 Disconnect the battery negative lead.
2 Remove the air cleaner assembly.
3 Remove the alternator.
4 Referring to Part D of this Chapter, release
the lambda sensor multiplug from the gearbox
bracket and disconnect the plug from the
sensor.
5 Firmly apply the handbrake then jack up the
front of the vehicle and support it on axle
stands.
6 Unscrew the nuts securing the exhaust
front pipe to the manifold, then disconnect the
pipe and collect the gasket.

16.38 Disconnect fuel return hose (A) and
expansion tank hose (B)
7 Undo the five nuts securing the exhaust
manifold to the cylinder head, then carefully
manoeuvre the manifold out of the engine
compartment. Remove the manifold gasket
and discard it.
8 Examine all the exhaust manifold studs for
signs of damage and corrosion. Remove all
traces of corrosion and repair or renew any
damaged studs.
Refitting
9 Refitting is the reverse of the removal
procedure, noting the following:
a) Ensure that the manifold and cylinder
head sealing faces are clean and flat, then
fit a new manifold gasket.
b) Working in the sequence shown (see
illustration), tighten the manifold
retaining nuts evenly to the specified
torque wrench setting.
c) Tighten all other disturbed nuts and bolts
to their specified torque wrench settings
(where given).
18 Exhaust system -
inspection,removal and
refitting
1 Refer to Section 18 in Part A of this
Chapter. Note that on models fitted with a
closed-loop catalytic converter, the lambda
sensor must be removed or its wiring
disconnected whenever the exhaust system
front pipe is disconnected from the manifold.
