1. Install intake manifold and new gaskets, with wiring
harness attached, to cylinder heads. Slide any wiring
harness clips onto appropriate bolts before installing.
Make sure gaskets are in proper orientation. Torque
screws in 2 stages, fi rst to 7.8 N·m (69 in. lb.), then
to 10.5 N·m (93 in. lb.), using sequence shown.
2. Install ground terminal to crankcase post with a
silver screw. Torque to 4.0 N·m (35 in. lb.) into used
holes or 6.2 N·m (55 in. lb.) into new holes.
3. Install wire harness clip to other crankcase post and
torque screw to 4.0 N·m (35 in. lb.) into used holes
or 6.2 N·m (55 in. lb.) into new holes.
4. Place wire harness conduit in clip and snap clip
together.
Install Fuel Injectors
NOTE: Ensure all parts are clean, undamaged and free
of debris and make sure electrical connectors
have seal in place.
1. Lightly lubricate fuel injector O-rings with clean
engine oil.
2. Push retaining clip onto fuel injector, aligning clip.
3. Press fuel injector into fuel injector cap until retaining
clip snaps into place.
4. Press fuel injector into bore in intake manifold and
rotate to original position.
5. Install fuel injector cap screw into intake manifold
and torque to 7.3 N·m (65 in. lb.).
6. Push electrical connector on fuel injector making
sure a good connection is made.
7. Repeat steps 1 through 6 for other fuel injector.
