Figure 1 - Prepping The Block
Disconnect battery; remove all existing accessory drive brackets and
components from motor.
Remove water pump, scrape away any existing gasket material with a
gasket scraper and dress surface with a Scotch Brite® pad.
Clean and prep threads on engine block at water pump and driver side
bosses by crank (for power steering kits), use a 3/8-16 thread chaser if
necessary. Thread chasers are available at your local auto parts store or tool
dealer and are different from a thread cutting tool.
Apply RTV sealer to one end of the three 3/8-16 x 3” threaded studs and
thread two studs into the driver side water pump mount holes and one stud
into the upper passenger side mount hole and tighten.
Apply RTV sealer to one end of the remaining 3/8-16 x 4” stud and thread
into the bottom passenger side mount hole and tighten. The studs can eas-
ily be tightened by threading two 3/8-16 zinc coated nuts onto the stud and
tighten them against each other to act as a drive nut.*
Figure 2 - Install Alternator & A/C Brackets
Install the large O-rings into both sides of the passenger side compressor
bracket by seating them into the recessed groves, install the small by-pass
O-rings in the same manner. Place bracket over studs and seat up against
engine block.
Install the large O-rings into both sides of the driver side alternator bracket by
seating them into the recessed groves. Place bracket over studs and seat up
against engine block.
For kits with power steering – apply anti-seize to the threads of the two
3/8-16 x 2” socket head cap screws and thread through the power steering
bracket, alternator bracket and into engine block and finger tighten.
For kits without power steering – apply anti-seize to the threads of the two
3/8-16 x 1-1/4” socket head cap screws and thread through the alternator
bracket and into engine block and finger tighten.

Alternator: Apply anti-seize to the threads of the 10mm-1.5 x 80mm ARP 12pt.
cap screw and the 8mm-1.25 x 25mm ARP 12pt. cap screw. Place alternator
between lower bridge bracket and alternator bracket and thread the long
ARP 12pt. cap screw through the bridge bracket, alternator and into the
alternator bracket and finger tighten. 10mm shim washers are provided to
shim the lower alternator boss to the bridge bracket. The alternator boss may
vary in width due to the polishing process. Place the 8mm slide spacer* on
the short ARP 12pt. cap screw, align top alternator boss with bridge bracket
and thread the cap screw with slide spacer through bridge bracket and into
alternator boss and finger tighten.

compressor mount boss and align with compressor bracket on motor and
finger tighten. Thread one 8mm ARP 12pt. cap screw through bridge bracket
and into lower compressor boss and finger tighten. Place the 8mm slide
spacer* on the short ARP 12pt. cap screw, align top compressor boss with

Figure 7 - Install A/C Compressor Manifold
Compressor Manifold – Read the precautions below, BEFORE installing the
compressor manifold. To install the manifold remove the bolts & protective
cap, being sure to leave the o-rings in place on compressor. Apply anti-seize
to the threads of the two 8mm-1.25 x 25mm socket head cap screws. Place
manifold on compressor and attach with the two 8mm cap screws and
tighten firmly. Attach compressor lines at this point or seal off threaded ends
of manifold.
IMPORTANT
• Only remove sealed cap on compressor and install manifold if you plan on
charging your system immediately, leaving the compressor open to outside
air can introduce moisture into the system causing the cooling system not to
operate properly.
• Never connect the compressor clutch wire and run the compressor unless
the system is charged. Serious damage may occur to compressor. Do not
install the manifold unless you are going to finish installing the a/c hoses and
never connect the compressor clutch wire until system is ready to charge
with Freon.
• Although the compressor is supplied with oil, the level may not be correct
for the entire system. Consult the instruction manual of the air conditioning
unit for proper levels and system charging procedures.
• Billet Specialties recommends having your air conditioning charged and
serviced by an automotive air conditioning service center with the proper
equipment to ensure many years of proper operation.
