Torque sequence of lower intake on a 2003 windstar 3.8

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

Please note that this information is provided as-is and I recommend consulting a professional mechanic for any further assistance.

This is elusive online. I have found an image file relevant to the sequence.

It does not include the torque's however. Although I find references to the applicable torques being between 71 and 106 in lbs.I hesitate to suggest such as inappropriate torque can crack the manifold. If you become a free member of Autozone, you can download their variation of a service manual for the 2003 Taurus. The user manuals do not include torques. An alternative is to sign into https://cardiagn.com/ford/taurus/. You can find a generalized torque chart at https://www.taurusclub.com/forum/82-maintenance-repair/349683-trying-find-official-torque-specs.html but determining the steel quality of your bolts strikes me as an esoteric bit of knowledge. Here is a YouTube regarding removal of the manifold: https://www.youtube.com/watch?v=s8o6UWs17bU

Hopefully, one of these service manuals will have the information you seek.

Remove the 12 bolts that hold the intake to the lower section and disconnect all the hoses and linkages. Replace the lower gaskets and torque the manifold in a radiating sequence in this order.
stages to tighten
stage 1 - 59 inch pounds
stage 2 - 66 inch pounds
stage 3 - 90 degrees

Lower intake torque is done in three steps:
Step 1 27 in. lbs
Step 2 106 in. lbs
Step 3 133 in. lbs
Sequence is:

<- Front of Engine
7 1 3 5


8 4 2 6

Could find no specific sequence for upper intake, but they torque in 2 steps.
Step 1 44 in. lbs
Step 2 89 in. lbs

Hope this helps :)

Apply sealer to the lower intake manifold bolts prior to installation. On the 5.0L and 5.7L engines, install the bolts and torque in sequence as follows:
Step 1: 71 inch lbs. (8 Nm).
Step 2: 106 inch lbs. (12 Nm).
Step 3: 11 ft. lbs. (15 Nm).

Upper intake manifold mounting bolts/studs, torque in a crisscross pattern as follows:

1. Step 1: Torque the bolts/studs to 44 inch lbs. (5 Nm).
   
2. Step 2: Torque the bolts/studs to 83 inch lbs. (10 Nm).

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day and Merry X-mas.

start in the center working in an expanding square pattern crossing over the manifold on the first 2 bolts. tighten in 3 steps. these are low torque fasteners, don't over tighten & use locktite.
If reusing the fasteners, apply threadlock GM P/N 12345382 or equivalent to the threads of the lower intake manifold bolts.
Install the lower intake manifold bolts.

Notice: Proper lower intake manifold fastener tightening sequence and torque is critical. Always follow the tightening sequence, and torque the intake manifold bolts using the 3 step method. Failing to do so may distort the crankshaft bearing bore alignment and cause damage to the crankshaft bearings.

Tighten the lower intake manifold bolts.

from front of engine tighten 2 bolt back left side, then 3rd bolt back right side, then 3 bolt back left side, then 2nd bolt back right side, then back bolt left side, back bolt right side, then front bolt left side, then front bolt right side

Tighten the bolts on the first pass in sequence (1-8) to 3 N·m (27 lb in).
Tighten the bolts on the second pass in sequence (1-8) to 12 N·m (106 lb in).
Tighten the bolts on the final pass in sequence (1-8) to 15 N·m (11 lb ft).
