FACTORY HOSE TO BE REPLACED
(Cars equipped w/power steering cooler)

6. RADIATOR HOSE MODIFICATION
A. The object of this section is to route the radiator
hose as close to the radiator as possible to provide
room for the supercharger belt and spring
tensioner.
B. Drain the coolant system until the upper radiator
hose can be removed.
C. Leaving the straight legs as long as possible, trim
the supplied hose per Fig. 6-a.
D. (Vehicles with power steering cooler) Remove the
radiator hose connecting the engine to the power
steering cooler. Install the trimmed hose in place
of the original so the free end is routed behind
the A/C line. Make sure the hose is routed
between the radiator shroud and the air
conditioning line.
E. (Vehicles without power steering cooler) Remove
the engine side of the upper radiator hose. Install
the trimmed hose onto the engine and route the
free end behind the A/C line. Cut the original
radiator hose so it will connect to the installed
hose with the supplied 1-3/8" hose mender. Make
sure the hose is routed between the radiator
shroud and the air conditioning line.
7. POWER STEERING INSTALLATION
A. Remove the reservoir from the power steering
pump and set aside.
B. Loosely install the power steering pump supply
fitting retaining bracket on the mounting bracket
with 1/4-20-1/2” long socket head cap screws.
C. If separate from pressure line, install the 18mm
fitting in the power steering rack and the 16mm
fitting in the power steering pump.
D. Loosely install the -6 90
°
fitting on the power
steering rack. Point the fitting upwards.
E. Attach the supplied pressure line to the power
steering pump angled so as not to contact the
power steering pump pulley when installed.
F. With the factory O-ring positioned on its smallest
bore, insert the supplied power steering pump
supply fitting into the pump and push until a
positive stop is felt.
G. Assemble the power steering pump and front
supercharger support bracket using two 3” x
5/16-18 through bolts and the factory 8mm bolt
in its original location. (See
Fig. 7-a.)
