Exhaust Manifold

Tighten the four nuts to 25 Nm (18 ft. lbs.).
After the nuts are tightened to 25 Nm (18 ft. lbs.) once, repeat the step to be sure that all nuts are at the proper torque.






NOTE: Replace any stud that loosens during removal. If a stud is to be replaced, tighten the new stud to 11 Nm (97 in. lbs.). Age of the vehicle and environment impact how many of the studs come out. Any that stay in the head also need to be checked for the 11 N-m (97 in. lbs.).

NOTE: The turbocharger has been removed for clarity.

Install the nine exhaust manifold washers and new nuts (1).
1) Tighten to 15 Nm (133 in. lbs.) in order from 1 to 9.
2) Retighten to 15 Nm (133 in. lbs.) in order from 1 to 4 only.
3) Add additional 30 degrees of rotation to all in order from 1 to 9.
