Typical example
(1) Locating pad
The pipe plug at location (2) is installed in the cylinder head for engines with dry exhaust manifolds. If the pipe plug is not installed into the water passage, the coolant will leak and engine damage will result. For engines with dry exhaust manifolds, make sure that the pipe plug is installed.
Illustration 2 g01611158 (3) Before assembly, lubricate the thread of the pipe plug with Loctite C5A Copper Anti-Seize. Use the following procedure to tighten the bolts of the cylinder head that is shown in Illustration 2:Note: Before assembly, coat the threads of the bolt with clean engine oil.
Tighten the bolt 1 through bolt 8 in the numerical sequence to 30 5 N m (22 4 lb ft).
Tighten the bolt 1 through bolt 8 in the numerical sequence to 270 35 N m (200 26 lb ft).
Again tighten the bolt 1 through bolt 8 in the numerical sequence to 450 20 N m (330 15 lb ft). Note: Tighten the bolts (4) only after the cylinder head bolts have been given final torque. (4) Torque for two bolts ... 55 10 N m (41 7 lb ft)
