Exhaust manifold
Tightening sequence for the exhaust manifold
Note: Use a centering tool in at least one oversize hole per exhaust manifold section in order to align the exhaust manifolds. Do not remove the centering tool until removal is required to tighten the locknuts.Use the following procedure to tighten the exhaust manifold on the cylinder head:
Tighten locknuts 6 through 17 in a numerical sequence to 20 3 N m (15 2 lb ft).
Again tighten locknuts 6 through 17 in a numerical sequence to 38 5 N m (28 4 lb ft). (2) Coat the female ends of the two exhaust manifolds with clean engine oil. Note: Apply 4C-5599 Anti-Seize Compound on the taperlock studs (3) before assembly. (3) Torque for two taperlock studs ... 35 5 N m (26 4 lb ft) (4) Apply a thin coat of 2P-2333 High Temperature Sealer to the outside diameter of the male ends of the four exhaust manifolds prior to assembly. Remove excess sealer from the assembled joint. (5) Torque for 12 taperlock studs ... 35 5 N m (26 4 lb ft)
