Would you happen to have the torque sequence diagrams on the intake manifold, exhaust manifold, fuel injection cross over rail and the cylinder deactivation manifold? I would like to know the torque also for the cylinder deactivation manifold.

Thanks so much!

Hello,

Here are the intake manifold bolt torque and sequence and a guide to give you an idea of what you are in for when doing the job:

Tighten the intake manifold bolts to specifications.

Tighten the bolts a first pass in the sequence shown to 5 N.m (44 lb in).
Tighten the bolts a final pass in the sequence shown to 10 N.m (89 lb in).

Install the exhaust manifold bolts.

Tighten the bolts a first pass to 15 N.m (11 lb ft). Tighten the exhaust manifold bolts beginning with the center 2 bolts. Alternate from side-to-side, and work toward the outside bolts.

Tighten the bolts a final pass to 20 N.m (15 lb ft). Tighten the exhaust manifold bolts beginning with the center two bolts. Alternate from side-to-side, and work toward the outside bolts.

Check out the intake manifold diagrams (below).

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken
