Fuel/exhaust systems - single-point fuel injection models / Inlet manifold - removal and refitting

1 Remove the throttle body (Section 12).

2 Drain the cooling system (see Chapter 1).

3 Slacken the retaining clip and disconnect the coolant hose(s) from the manifold.

4 Slacken the retaining clip and disconnect the vacuum servo unit hose from the left-hand side of the manifold.

5 Make a final check that all the necessary vacuum/breather hoses have been disconnected from the manifold.

6 Unscrew the retaining nuts, then manoeuvre the manifold away from the head and out of the engine compartment. Note that there is no manifold gasket.

7 Refitting is the reverse of the removal procedure, noting the following points: a) Ensure that the manifold and cylinder head mating surfaces are clean and dry, and apply a thin coating of suitable sealing compound to the manifold mating surface. Refit the manifold and tighten its retaining nuts to the specified torque.

b) Ensure that all relevant hoses are reconnected to their original positions and securely held (where necessary) by their retaining clips.

c) Refit the throttle body as described in Section 12.

d) On completion, refill the cooling system as described in Chapter 1.
