4. Remove the distributor cap and scribe the rotor position relative to the
distributor body, and engine.
5. Remove the distributor.
6. If applicable, remove the alternator upper bracket. As required, remove
the air cleaner bracket, and accelerator bellcrank.
7. Remove the manifold-to-head attachi ng bolts, then remove the manifold
and carburetor as an assembly.
8. Mark and disconnect all emission re lated items (e.g.: wiring, vacuum
hoses, etc.) which are connected to manifold mounted items.

ft. lbs. (34-61 Nm).
22. Connect the heater hose to the intake manifold.

Sealing of the intake mani fold to the "V" of the engine is obtained by employing
an intermediate torque specification to a ll the attaching bolts, alternately, in the
proper sequence. This step is used to rock the manifold into place before
applying the final torque figur e. Failure to follow this two-step procedure can
result in possible leaks.
