Service Procedure

1. Open the hood.

2. Disconnect the PCV make-up air tube at the in-line connector (3.7L and 4.7L) or at the engine oil filler assembly (5.7L).

3. Disconnect the air intake tube from the engine intake resonator.

4. Disconnect the three (3) air cleaner cover clips and then remove the air cleaner cover, resonator and inlet tube as an assembly.





5. Inspect the positive battery cable where it passes the right upper control arm bracket (Figure 1). If the wiring insulation is damaged from contact with the bracket, wrap it with high quality electrical tape. If the battery cable copper wiring strands are visible, the battery cable must be replaced (P/N 56049174AI (4.7L), 56049175AI (5.7L) or 56049456AI (3.7L)).

NOTE:
The positive battery cable must be secured with a tie strap even if the cable has been replaced.





6. Reposition the positive battery cable away from the upper control arm bracket and secure it to the main battery harness bundle with the provided tie strap (Figure 2). Locate the tie strap approximately 8" (200 mm) below the battery tray clip.

IMPORTANT:
Do NOT locate the tie strap on the blue fusible link portion of the cable.

7. Rotate the lower end of the battery cable bundle counter-clockwise to position it perpendicular to the battery. Ensure that the battery harness bundle is at least 1" (25 mm) away from the control arm bracket.

8. Inspect the battery cable routing to ensure all clips remain secure. If the battery cable to right front valve cover stud clip (4.7L/5.7L) is broken, replace it with a tie strap/clip P/N 55366863AA.

9. Install the air cleaner cover assembly. Secure the cover with the three (3) clips.

10. Connect the air intake tube to the engine intake resonator. Tighten the intake tube clamp to 33 in-lbs (3.7 N.m).

11. Connect the PCV make-up air tube at the in-line connector or at the oil filler assembly.
