What are the torque specs for the upper and lower intake in a Chevy Venture?

Answer

If this is the V-6, then you must have a common problem...lower intake leaks coolant.

The torque spec for the lower manifold is:

First pass: 60 inch pounds

Second pass: 110 inch pounds

Last (outer bolts only): 18 foot pounds

Upper intake is a total 88 inch pounds in at least two steps.
