Upper Manifold (Fluid Induction System)
***This procedure has been updated by TSB Bulletin No.: 47-61-29,Date: September, 1994***
Outlined below are appropriate service procedures for servicing the fluid induction system (intake manifold). During the 1993 model year, grommet style
top cover fasteners were incorporated into the fluid induction system. When replacing a top cover or lower housing, the fluid induction system must be
updated with the new grommet style top cover, grommet fasteners, fuel injector wiring harness cover and gasket. Use the following guidelines to
determine which style top cover is on the fluid induction system (see Figure 1).
Top Cover During the 1993 model year, a "grommet" style fastening system was incorporated into the top cover. These fastening design changes include
12 Torx head screws (2 - silver in color), 12 oval shaped rubber spacers with steel washers and a raised step on the top cover to accommodate the new
screws and spacers (see Figure 1). These new top cover enhancements include a new design wiring harness cover, gasket and ignition wire harness
channel. Along with these new top cover enhancements, a new design wiring harness cover and gasket are also used.
WHEN TOP COVER REPLACEMENT IS NECESSARY:
1.
Inspect the top cover for rubber grommets beneath the cover screws and raised step on the cover. If these features are present, install a new top
cover, part number 17090937. Refer to installation procedures described in this bulletin below.
2.
If the top cover is a non-grommet design, replace the top cover with the "grommet style" cover kit, part number 17113193, which contains:
Grommet bolt style cover
Grommet style bolts (12 Torx head screws with spacers)
Wiring harness cover
Gasket
Spark plug wire channel
