Typical example of exhaust manifoldNote: Put 5P-3931 Anti-Seize Compound on the threads, the studs, the plugs, the nuts and the bolts for the exhaust manifolds and couplings. Put a thin coat of 2P-2333 High Temperature Sealer on the OD of the male end of the exhaust manifold. Put oil on the female ends of the exhaust manifold.The tightening sequence for the nuts that hold the exhaust manifold to the cylinder head follows:
In a numerical sequence, tighten nuts 1 through 12.Torque for nuts ... 20 3 N m (15 2 lb ft)
In a numerical sequence, tighten nuts 1 through 12 again.Torque for nuts ... 38 5 N m (28 4 lb ft)
