Torque specs for upper intake manifold for an '07 Chrysler Pacifica 4.0

I found a forum post on Jeep Enthusiast Forums that provides the tightening sequence for the 3.8L upper intake plenum of a 2007 Chrysler TWC. Here are the steps:

Remove covering on lower intake manifold and clean surfaces.
Inspect manifold gasket condition. Gaskets can be re-used, if not damaged. Position new gasket in seal channel and press lightly in-place. Repeat procedure for each gasket position.
Position upper manifold on lower manifold.

Apply Mopar® Lock & Seal Adhesive (Medium Strength Threadlocker) to each upper intake manifold bolt.
Install and tighten bolts to 12 N·m (105 in. lbs.) using torque sequence.

Here is the torque sequence for the 3.8L upper intake plenum:

6 2 4
5 1 3

INSTALLATION - UPPER INTAKE MANIFOLD
1)Clean and inspect gasket sealing surfaces.
2)Position new gasket.
3)Install the throttle body on the upper intake (if required).
4)Install upper intake manifold and hand start all attaching bolts.
5)Tighten bolts gradually starting in the center working outward until a torque of 12 Nm (105 inch lbs.) is obtained.
6)Install the front and rear intake manifold support brackets.
7)Install the oil level indicator and oil fill tube to intake manifold bolts (Fig. 155).
8)Install the EGR tube.
9)Connect vacuum lines to the following (Fig. 156):
Positive Crankcase Ventilation (PCV) Valve
EVAP Purge Solenoid
Power Brake Booster
10)Install alternator support bracket (Fig. 156).
11)Connect electrical connectors to the following (Fig. 157):
Manifold Tuning Valve (MTV)
Exhaust Gas Recirculation (EGR)
Throttle Position Sensor (TPS)
Idle Air Control (IAC)
Manifold Absolute Pressure (MAP)
12)Install the throttle and speed control cable bracket and retaining bolts.
13)Install throttle and speed control cables to bracket and throttle arm.
14)Install air cleaner housing and inlet hose.
15)Install the engine cover.
16)Connect negative battery cable.

Tighten bolts gradually starting in the center working outward until a torque of 12 Nm (105 inch lbs.) is obtained.

Sorry first attempt got sent by accident

Upper intake manifold bolts/nuts 168 in-lbs

Lower intake manifold nuts are done in 4 steps

Step1. Front nuts 61 in-lbs
Step2. Rear nuts 185 in-lbs
Step3. Front nuts 185 in-lbs
Step4. Repeat Steps 2 and 3

for the head

Step 1: Bolts 1 - 8 to 61 N·m (45 ft. lbs.)

† Step 2: Bolts 1 - 8 to 88 N·m (65 ft. lbs.)

† Step 3: Bolts 1 - 8 (again) to 88 N·m (65 ft. lbs.)

† Step 4: Bolts 1 - 8 turn an additional 1/4 Turn.

(Do not use a torque wrench for this step.)

NOTE: Bolt torque after 1/4 turn should be over 122
N·m (90 ft. lbs.). If not, replace the bolt.

Fig. Intake manifold bolt torque sequence 2.7L engine

Upper intake manifold with a new gasket on the lower intake manifold and torque the bolts, in sequence, to: 105 inch lbs. (12 Nm)

Hope helps (remember to rate this answer). Good job.

(step 1 ) the torque specs for the heads are---1998 through 2001 are 37 foot lbs. ( step 2) rotate an additional 90-degrees (1/4 turn). intake manifold bolts ( lower ) step 1-- 62 in-lbs, step 2--115 in-lbs. intake manifold bolts/studs ( upper ) 18 ft-lbs. this is for the 3.1 v-6, have a good day!

If you are looking at the engine from the front and the large hose is at the bottom right the tightening sequence is from upper left to right 6237 bottom left to right 5148 just like I typed it torque is 250 inch pounds on lower intake and 105 inch pounds on the upper intake. So when you look at those numbers you tighten 12345678 in that order to 250 inch pounds in 3 increments then install the top intake.
