folds on the two studs on cylinder heads, using new
gaskets. Install the conical washers and nuts on the
studs (Fig. 10).
(2) Install the two screws and the conical washers
at the inner ends of the outboard arms of the mani-
fold. Install the two screws without washers on the
center arm of the manifold (Fig. 10). Tighten the
screws and nuts, starting at the center arm and work-
ing outward, to 15 foot-pounds.
(3) Assemble the exhaust pipe to the manifold, and
secure with bolts, nuts and washers. Tighten the nuts
to 25-45 foot-pounds. On the left hand manifold, at-
tach the two braces to the manifold with bolt, nut and
washer. Tighten the nut to 30 foot-pounds.

Remove the Intake Manifold as outlined in Group
9 "Engine."
Servicing
(1) Clean the manifold (Figs. 11 and 12) in solvent
and blow dry with compressed air.
(2) Inspect the exhaust crossover passages (Figs.
11 and 12) and pressure test for any leakage into the
intake passages.

(3) Inspect the mating surfaces for parallelism.
(4) Use new gaskets when installing the manifold.
Reinstall the manifold as outlined in Group 9, "En-
gine."

Engines)
(1) Disconnect the spark plug cables.
(2) Remove the alternator.
(3) Disconnect the exhaust pipe at the exhaust
manifold.
(4) Remove the stud nuts attaching the exhaust
manifolds to the cylinder heads. Slide the manifolds
off the studs and away from the cylinder heads.
(5) Clean the manifolds in solvent and blow dry
with compressed air.
(6) Inspect the manifolds for cracks and distortion.
(7) On the right hand manifold, test the heat con-
trol valve for free operation. If necessary to free up,
apply Manifold Heat Control Solvent, Part Number
1879318, as outlined in Paragraph "Manifold Heat
Control Valve."
