Installation
1. Align upper holes in blower housing with those in
intake manifold. Align lower holes in blower housing
with weld nuts on heat shield and flywheel backplate
flanges.
2. On cylinder 1 side, proceed as follows:
A. Start two lower hex flange screws to fasten
blower housing to heat shield and flywheel
backplate flanges.
B. Start upper inside hex flange screw to fasten
lifting eye, mechanical diaphragm fuel pump
bracket, blower housing, and heat shield flange to
intake manifold.
C. Start upper outside hex flange screw to fasten
lifting eye, mechanical diaphragm fuel pump
bracket, and blower housing to intake manifold.
3. On cylinder 2 side, proceed as follows:
A. Start two lower hex flange screws to fasten oil
cooler bracket and blower housing to heat shield
and flywheel backplate flanges.
B. Start upper inside hex flange screw to fasten fuel
pump module cover bracket, blower housing and
heat shield flange to intake manifold.
C. Start upper outside hex flange screw to fasten
fuel pump module cover bracket and blower
housing to intake manifold.
4. Alternately tighten four upper blower housing to
intake manifold screws to 135 lb-in (15 Nm) using a
crosswise pattern.
5. Alternately tighten four lower blower housing to heat
shield/flywheel backplate screws to 90 lb-in (10 Nm)
using a crosswise pattern.
6. Install two hex flange screws to fasten valve cover to
cylinder head. Alternately tighten screws to 35-48 lb-
in (4-5 Nm).
