Exhaust manifold - removal and refitting

Note: A new gasket will be required on refitting.

Removal
1 Disconnect the battery negative lead.

2 On carburettor and CFI engine models remove the air cleaner as described in the appropriate Part of this Chapter.

3 Remove the turbocharger on RS Turbo models as described in Part B of this Chapter.

4 On EFI engines, unbolt the air inlet pipe and move it to one side.

5 Where applicable, unbolt the hot air shroud for access to the manifold securing nuts.

6 Support the exhaust system on a jack or blocks, then disconnect the downpipe at the manifold. On models with CFI engines, take care not to strain the HEGO sensor wiring (see Part C of this Chapter).

7 Undo the nuts securing the manifold to the cylinder head and remove it from the engine.

Recover the manifold gasket.

Refitting
8 Refitting is the reverse sequence to removal, but refit the turbocharger on RS Turbo models as described in Part B of this Chapter.
