The air pump and its bracket were then relocated
onto a pair of threaded holes on the bottom of
the ProCharger head unit main bracket using the
factory air pump bracket bolts.
The sixth major group of steps is the instal-
lation of the intercooler and the tube routing.
Again, it’s a good thing the instruction book is
so detailed, because there are about a dozen
things to be done before the intercooler can
be installed, ranging from the removal of
radiator support bars, plastic air deflectors,
air inlet tube, and the radiator cover to installa-
tion of radiator support spacers and brackets.
All this has to happen before a^3 ⁄ 8 -inch hole
can be drilled in the two lower A/C condenser
tabs to allow the fitting of kit-provided clip
nuts to all four A/C condenser tabs.
We loosely mounted the intercooler brackets
to the intercooler, and then loosely bolted the
brackets to the clip nuts installed in the A/C
condenser tabs.
We assembled the surge valve, surge valve
filter, and 1^1 ⁄ 2 -inch rubber surge valve hose
before installation.The IAT sensor that had been carefully
removed from the factory air inlet was plugged
into the ProCharger tube that fits between the
driver-side molded rubber tube coming from
the intercooler and the throttle-body tube.At this time, the fan and its shroud had been
reinstalled so we could check for clearance
around it when installing the new tubing for
the intercooler system. Some minor cutting
for “clearance” had to be done for the air inlet
that was installed later.With the horns back in place (their mounting
tabs had to be bent just enough so that when
reinstalled the horns don’t touch the inter-
cooler), the two molded rubber tubes for the
intercooler were inserted through the openings
on each side of the radiator. The rubber tubes
were then secured to the intercooler with hose
clamps but left loose until final adjustment.The rubber elbow-shaped throttle-body
tube was slid over the 3 -inch end of the IAT
sensor tube and then connected to the throt-
tle body. Once all three driver-side tubes
going from intercooler to the throttle body
were adjusted and properly aligned, all hose
clamps were tightened.Finishing out the passenger-side tubing from
the intercooler to the ProCharger head unit
wrapped up the installation of the intercooler
and its tubing. Part of that passenger-side
three-part tubing system was a surge tube in
the middle with a 1^1 ⁄ 2 -inch rubber hose that
leads to the surge valve.A bubble level was used to make sure
the intercooler was mounted perfectly
level before all the intercooler’s mounting
hardware and brackets were fully tightened.
