7. Prior to reinstalling the igniter-injector, apply a high temperature, conductive, anti-seize
compound to the threads.
The igniter-injector replacement kit (P/N 58023) includes three clocking
(indexing) washers, which are used, as needed, so that when the igniter-
injector is fastened in place, the gas injector tube is pointing outward, toward
the intake manifold perimeter.
8. Refer to Figure 6-2 and reinstall the igniter-injector on the intake manifold flange. Install one
to three clocking washers, as needed, to position the igniter-injector's gas tube so that it is
pointing outward, toward the outer-edge of the intake manifold flange. Torque to 15 ft-lbs
(20.34 Nm). Do not over tighten.
