Chapter 11 INLET AND EXHAUST SYSTEMS
3. Inlet and Exhaust Systems - Install
Install the parts in the reverse order of the disassemble sequence.(Refer to the illustration for disassembling.)
Thoroughly clean and dry the inlet and exhaust passages.
3.1 Exhaust Manifold - Install
3.1.1 Cautions during installation of exhaust manifold
(1) Make sure that the centers of exhaust manifold and cou-
pling are aligned when installing.The misalignment of
exhaust manifold and coupling causes gas leakage.
(2) Install the exhaust gasket so that the side having letters
is on the exhaust manifold side.
(3) When installing the exhaust gaskets, always replace all
the gaskets with new ones.
Cautions during installation of exhaust manifold
3.1.2 Exhaust Manifold Coupling - Tighten
(1) Apply MOLYKOTE (molybdenum disulfide anti-seize)
or equivalent to the bolt.
(2) Tighten the nuts to the specified torque.
(3) Lightly shake the outer circumference of exhaust mani-
fold coupling to make a snug contact between exhaust
manifold mating face and exhaust manifold coupling
taper face.
(4) Tighten the nuts to the specified torque.
(5) Lightly shake again to verify the snug fitting.
