The sequence and the torque values can be had via a Chilton's manual or Haynes manual.

I have searched for these values, but the sites always make reference to the manuals.
Average price of a manual can be from $5.95 to $25.

good luck and don't forget to vote!!!

What do the intake manifold bolts for a 2002 Chevy Malibu with a 3.1L need to be torqued to?


Pretend the picture is lower intake manifold, that is the tightening sequence.
1st step 5 ft lbs
2nd step bolts 1--4 9.6 ft lbs
3rd step bolts 5--8 18 ft lbs
The upper intake manifold use about the same sequence tighten to 18 ft lbs.
If you don't like ft lbs use inch lbs.
If the upper intake manifold is plastic, be careful with that.
