6. Torque the screws to 4.0-6.2 N·m (35-55 in. lb.) .
7. Repeat steps 4 through 6 for the other ignition
module.
8. Rotate the flywheel back and forth checking for
clearance between the magnet and ignition
modules. Make sure the magnet does not strike
the modules. Check the gap with a feeler gauge
and readjust if necessary. Final air gap:
0.280/0.330 mm (0.011/0.013 in.) .
Install Intake Manifold
1. Install the intake manifold and new gaskets or
O-Rings (plastic manifold), with wiring harness
attached, to the cylinder heads. Slide any wiring
harness clips onto the appropriate bolts before
installing. Make sure the gaskets are in the
proper orientation. Torque the four screws in
two stages, first to
7.4 N·m (66 in. lb.),
then to
9.9 N·m (88 in. lb.),
using the sequence shown in
Figure 11-51.

Sealant
Figure 11-51. Intake Manifold Torque Sequence.
Figure 11-52. Sealant Applied to Terminals.
NOTE: If the wires were disconnected from the
ignition modules on engines with SMART-
SPARK
™
, reattach the leads and seal the base
of the terminal connectors with GE/
Novaguard G661 (see Section 2
) or Fel-Pro
Lubri-Sel dielectric compound. The beads
should overlap between the terminals* to
form a solid bridge of compound. See Figure
11-52. Do not put any compound inside the
terminals.
*The 24 584 15-S ignition modules have a
separator barrier between the terminals. On these
modules, seal the base of the terminals, but it is
not necessary to have overlapping beads of
sealant between the connections.
2. Two-Barrel Manifold (Carburetor) Models:
Route the wiring harness through the mounting
clip on the underside of debris shield if separated
earlier. Carefully position the debris shield to the
rear as far as possible. See Figure 11-53.

Models).
