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 4 through 15 in a numerical sequence to 20 3 N m (15 2 lb ft).
Again tighten locknuts 4 through 15 in a numerical sequence to 38 5 N m (28 4 lb ft). Note: Apply 4C-5599 Anti-Seize Compound on the two taperlock studs before assembly. (3) Torque for two taperlock studs ... 35 5 N m (26 4 lb ft) (16) Torque for eight clamps ... 8.5 1.0 N m (75 9 lb in)
