Fuel/exhaust systems - carburettor models / Inlet manifold - removal and refitting


Note: Refer to the warning note in Section 1 before proceeding.

Removal
1 Remove the carburettor as described in Section 12.

2 On TU engines, drain the cooling system as described in Chapter 1, and disconnect the coolant hose from the base of the manifold.

3 Disconnect the brake vacuum servo hose at the manifold.

4 Disconnect the oil filler cap breather hose from the manifold.

5 Unbolt the oil filler tube bracket.

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

A gasket is however fitted on XU engines. On XU engines note the centre clamp secured by one nut (see illustration).

Refitting
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.

Fit a new gasket on XU engines, and apply a thin coating of suitable sealing compound to the manifold mating surface on TU engines. Install the manifold and tighten its retaining nuts to the specified torque setting.

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

c) Refit the carburettor as described in Section 12.

d) Where applicable, refill the cooling system as described in Chapter 1.
