4. MAIN BRACKET
A. To accommodate the relocation of the alternator
onto the new main bracket, the brown field wire
must be extended approximately 12”. Proceed by
cutting the wire approximately 4” from the factory
plug that attaches to the alternator. Splice the
supplied piece of brown wire into the cut wire by
soldering. Use the supplied piece of heat shrink
tubing to seal the joints. Re-wrap the wire/harness
with the supplied length of plastic flex-loom.
B. The transmission cooler lines must be bent down-
ward as far as possible (toward the frame) to
obtain alternator clearance. Rotate the lower ra-
diator hose clamp (at the water pump) 90
°
toward
the front (the clamp tabs should be facing the front
of the vehicle).
C. Attach the supplied stainless steel heat shield onto
the rear of the Vortech main bracket using the
supplied 1/4” hardware (see
Fig. 4-a ).
D. Place the mounting bracket on the front of the
passenger side cylinder head. Line up the bracket
with the holes on the front of the head and block
and start the 3/8-16 socket head bolt into the
lowest bracket hole. Install the two 3/8-16 x 1.25”
bolts and washers into the two remaining upper
holes. Torque the three bolts evenly.
E. Reattach the field wire and positive wire to the
alternator (make sure that the large positive wire
has the factory rubber boot properly secured to
prevent arcing to the heat shield). Using the sup-
plied 3/8-16 x 2.75” bolts and washers, attach the
alternator to the main bracket. Secure all alternator
wiring from heat and sharp objects.
F. Align the supercharger mounting plate with the
bracket and secure with the supplied 3/8-16 x 3/4”
bolts and AN washers.
G. Mount the supplied automatic belt tensioner onto
the main bracket. (See Fig. 4-b .) Rotate the unit so
that the small alignment pins fall into the corre-
sponding holes in the bracket. Secure the tensioner
using the supplied M10 bolt.
