Installation

1. Install the plenum pan, if removed, as follows:

a. Turn the intake manifold upside down. Support the manifold.

b. Place a new plenum pan gasket onto the seal rail of the intake manifold. Position the pan over the gasket. Align all the gasket and pan holes with the intake manifold.

c. Hand start all bolts.

Plenum Pan Bolt Tightening Sequence:

d. Tighten the bolts, in sequence, as follows:

Step 1 - Tighten bolts to 2.7 Nm (24 in. lbs.) torque.

Step 2 - Tighten bolts to 5.4 Nm (48 in. lbs.) torque.

Step 3 - Tighten bolts to 9.5 Nm (84 in. lbs.) torque.

Step 4 - Check that all bolts are tighten to 9.5 Nm (84 in. lbs.) torque.

2. Using a new gasket, install the throttle body onto the intake manifold. Tighten the bolts to 23 Nm (200 in. lbs.) torque.

Cross-Over Gaskets And Locator Dowels:

3. Place the 4 plastic locator dowels into the holes in the block.

4. Apply Mopar Silicone Rubber Adhesive Sealant, or equivalent, to the four corner joints. An excessive amount of sealant is not required to ensure a leak proof seal. However, an excessive amount of sealant may reduce the effectiveness of the flange gasket. The sealant should be slightly higher than the cross-over gaskets, approx. 5 mm (0.2 in).

5. Install the front and rear cross-over gaskets onto the dowels.

Intake Manifold Flange Gasket Alignment:

6. Install the flange gaskets. Ensure that the vertical port alignment tab is resting on the deck face of the block. Also the horizontal alignment tabs must be in position with the mating cylinder head gasket tabs. The words MANIFOLD SIDE should be visible on the center of each flange gasket.

7. Carefully lower intake manifold into position on the cylinder block and cylinder heads. Use the alignment dowels in the cross-over gaskets to position the intake manifold. After intake manifold is in place, inspect to make sure seals are in place.

8. Install the intake manifold bolts and tighten as follows:

Intake Manifold Bolt Tightening Sequence (V-8):

Step 1 - Tighten bolts 1 through 4, in sequence, to 8 Nm (72 in. lbs.) torque. Tighten in alternating steps 1.4 Nm (12 in. lbs.) torque at a time.

Step 2 - Tighten bolts 5 through 12, in sequence, to 8 Nm (72 in. lbs.) torque.

Step 3 - Check that all bolts are tighten to 8 Nm (72 in. lbs.) torque.

Step 4 - Tighten all bolts, in sequence, to 16 Nm (12 ft. lbs.) torque.

Step 5 - Check that all bolts are tighten to 16 Nm (12 ft. lbs.) torque.

9. Install closed crankcase ventilation and evaporation control systems.

10. Connect the coil wires.

11. Connect the heat indicator sending unit wire.

12. Connect the heater hoses and bypass hose.

13. Install distributor cap and wires.

14. Hook up-the return spring.

15. Connect the accelerator linkage and if so equipped, the speed control and transmission kick-down cables.

16. Install the fuel lines.

17. Install the generator and drive belt. Tighten generator mounting bolt to 41 Nm (30 ft. lbs.) torque. Tighten the adjusting strap bolt to 23 Nm (200 in. lbs.) torque.

18. Install the air cleaner.

19. Install the engine cover.

20. Fill cooling system.

21. Connect the negative cable to the battery.
