B. Loosen the water pump pulley bolts.
C. Remove the accessory drive belt.
D. Remove the "question mark" shaped crankcase
vent hose with attached fittings from between the
passenger side valve cover and the air inlet.
E. Remove all components that lead to the throttle
body including the rubber air inlet duct, mass air
flow (MAF) sensor, air filter assembly and intake
air temperature (IAT) sensor. Separate the MAF
and IAT sensors from the intake assembly and
set aside.
F. Mach 1 Only: Remove the shaker scoop (upper
and lower pieces), steel support bracket attached
to the top of the intake manifold and the aluminum
support bracket attached to the front cover of the
engine. (See Fig. 1-a, 1-b.)
G. Drain approximately one gallon of coolant from
the radiator. Remove the upper and lower radiator
hoses from the steel water tube junction located
around the alternator. Disconnect the water tem-
perature sensor connector located on the water
tube.

the engine by removing the 2 nuts. Pull the tube
directly upwards.

the factory water tube and set aside.
J. Remove the rear attachment screws that secure
the steel alternator support to the intake manifold.
Remove the two screws that attach the alternator

(the two front screws will remain).
