EGR EQUIPPED MODELS ONLY:
go to step 16.
NON EGR MODELS ONLY: remove the three studs
from the outlet of the left hand exhaust manifold.
These may be loosened by jamming two of the original
nuts against each other, and turning the inner nut, or
with a stud removal tool. save the three original nuts
for re-use.
NON EGR MODELS ONLY: Install three 10mm x 3 1 ⁄
2
”
long studs in the outlet of the left hand exhaust mani-
fold. These are contained in the Banks 6.2L Heavy duty
Parts kit.
NON EGR MODELS ONLY: Install the remaining
exhaust manifold outlet doughnut gasket in the cast
iron spacer (contained in the Heavy duty Parts Kit).
Tap the gasket in place with a hammer to seat it in the
spacer.
Install the crossover pipe between the right and
left exhaust manifolds. use two 3 ⁄
8
– 16 crimp
lock nuts to secure the 2-bolt flange to the right hand
manifold. On the left hand side, install the original ePR
valve (heat riser valve) if equipped, or the spacer from
the Heavy duty Parts Kit. Make sure a doughnut gasket
is in place in the ePR valve. Reuse the original metric
nuts. Leave nuts loose enough to adjust the position of
the pipe, then tighten.
If there are transmission coolant lines in close proxim-
ity to the right manifold and/or piping, carefully bend
lines away from high heat areas.
EGR EQUIPPED MODELS ONLY: re-connect vacu-
um line to the ePR valve on the left exhaust manifold.
A. Lower the vehicle, remove right hand battery.
connect the free end of the braided Teflon hose assem-
bly to the oil inlet fitting on the turbocharger. Tie the
hose to the cross-over casting at the front of the
engine with plastic cable ties. see figure 17. nOTe: if
the hose is not long enough to reach the turbo when
routed over the intake manifold, run the hose under
the manifold and to the turbo.
B. Remove plastic connector from inner fender panel
(push in on plastic to disengage from fender). save con-
nector for reinstallation. see figure 21.
Remove one screw at front corner of battery on right
hand inner fender panel to loosen air duct inside fend-
er. see figure 21.
Remove plastic button from inside air duct (use pliers
to pull out pin in center of button). Remove air duct
from inside of fender by pulling on duct and wiggling
back toward the firewall.
C. Use a hacksaw to cut off the portion of the duct
shown (see illustration). Removal of the forward por-
tion of the duct allows for greater air flow into the air
cleaner and increased performance.
D. Reinstall shortened air inlet duct and plastic con-
nector in fender, retain with plastic button. Make sure
all inner fender panel bolts are in place in the wheel
well, to prevent water from being thrown up by the tire
through holes where the air inlet duct could pick it up.
see figure 21.
nOTe: In extreme dust conditions, such as frequent
travel on dirt roads or in an agricultural usage, it is
advisable to block off the lower air inlet opening that
faces the ground using a piece of sheet metal or similar
method. This prevents premature contamination of the
air filter element by excessive dust kicked up by the
front tire. see figure 21 for location.
A. Locate the two bolt holes in the top of the
right hand inner fender panel, that previously
supported the air intake silencer. Measure, mark and
drill a third 3 ⁄
8
” dia. hole, 1 1 ⁄
8
” outboard (away from
engine) and in line with the existing two holes. see
figure 2.
