3. Set the intake manifold, with by-pass hose and
wiring harness attached, down into position
onto the gaskets and cylinder heads. Install and
finger tighten the six hex flange screws in their
appropriate locations. Make sure the clamps for
the wiring harness are positioned on the long
screw on each side. Torque the six intake
manifold mounting screws in two steps: first to
7.4 N·m (66 in. lb.), finally to 9.9 N·m (88 in. lb.)
in the sequence shown. See Figure 11-58.
