INTAKE AND EXHAUST MANIFOLDS
The Intake and exhaust manifolds are attached to the
cylinder head on the left side of the engine. A gasket is
used between the intake manifold and the cylinder head.
No gasket is used between the exhaust manifold and
cylinder head. An asbestos gasket is used at the mating
surfaces between the intake manifold and exhaust mani-
fold (fig. 1B-26). '
An exhaust gas recirculation (EGR) valve is mounted
on the side of the intake manifold. The intake manifold
has a metal plate incorporated into the area above the
exhaust manifold heat valve to create a hot spot that
improves fuel vaporization during warmup and shortens
choke operation time.
Intake ani Exlaust Manifoli Assembly Removal
(1) Remove air cleaner. Disconnect fuel line and
carburetor air horn vent hose and solenoid wire, if
equipped.
(2) Disconnect accelerator cable from accelerator
bellcrank.
(3) Disconnect PCV vacuum hose from intake
manifold.

(4) Remove spark CTO vacuum tubes and dis-
connect TCS solenoid vacuum valve wiring, if equipped.
(5) Disconnect vacuum hose from EGR valve.
(6) Disconnect Air Guard hoses at air pump and air
injection manifold check valve. Disconnect diverter vac-
uum hose and remove diverter valve with hoses.
(7) Remove air pump/power steering mounting
bracket, if equipped.
(8) Remove air pump.
(9) Detach power steering pump and set aside, if
equipped. Do not remove hoses.
(10) Remove air conditioning drive belt idler assem-
bly from cylinder head, if equipped.
(11) Disconnect exhaust pipe from manifold flange.
(12) Remove manifold attaching screws, nuts and
clamps. Remove intake and exhaust manifold as an as-
sembly. Discard gasket.
(13) Clean mating surfaces of manifolds and cylinder
head.
Intake and Eilaist Manifold Assembly Installation
(1) Position replacement intake manifold gasket on
cylinder head and install manifold assembly. Tighten
manifold attaching screws and nuts in sequence to 23
foot-pounds (31 N*m) torque (fig. 1B-27).
(2) Install flange gasket and connect exhaust pipe to
manifold flange.
(3) Connect fuel line and air horn vent hose to car-
buretor. Connect solenoid wire, if equipped.
