| 1 | 4 | 6V-3917 O-Ring Seal | Lubricate the bore lightly with 5P-3975 Rubber Lubricant . |
| 2 | 10 | 9F-2773 Bolt | Use the following procedure in order to assemble the aftercooler assembly and tighten the bolts: 1. Assemble the seals to the aftercooler core. 2. Temporarily secure the bottom seal with tape. Do not use an adhesive, a silicone lubricant, or any other lubricant for retention of the seal. 3. Assemble the aftercooler with seals to the inlet manifold. 4. Inspect the bottom seal in order to ensure that the seal is seating correctly in the recess. 5. Install the aftercooler cover. 6. Inspect the upper seal in order to ensure that the seal is seating correctly in the recess. 7. Install the cover bolts. Hand tighten the cover bolts. 8. Tighten the bolts in a numerical sequence as shown in Illustration 2 to 24 N·m (18 lb ft). 9. Again, tighten the bolts in a numerical sequence that is shown in Illustration 2 to 47 N·m (35 lb ft). 10. Remove the tape. |
| 3 | 2 | 3J-5389 Plug | Before assembly, apply Loctite C5A Copper anti-seize to the threads. Torque to 20 ± 5 N·m (177 ± 44 lb in). |
| 4 | 2 | 9X-8874 Bolt | Torque to 120 ± 20 N·m (89 ± 15 lb ft). |
| 5 | 12 | 6V-5101 O-Ring Seal | Lubricate the bore lightly with 5P-3975 Rubber Lubricant . |
| 6 | 4 | 6V-5103 O-Ring Seal | Lubricate the bore lightly with 5P-3975 Rubber Lubricant . |
