Bolt Tightening Procedure in the 416-8282 Block Spacer Gp
Item	Qty	Part	Specification Description
5	6	448-3955 Cylinder Head Fastener Gp	Use the following procedure to tighten the bolts for the cylinder head as shown in Illustration 2. 1. Before assembly, apply clean engine oil to the bolt threads. 2. Tighten bolt 1 through 8 in the numerical sequence to 30 ± 5 N·m (22 ± 4 lb ft). 3. Again, retighten bolts 1 through 8 in the numerical sequence to 100 ± 15 N·m (74 ± 11 lb ft). 4. Again, retighten bolts 1 through 8 in the numerical sequence to 450 ± 15 N·m (330 ± 11 lb ft). 5. Loosen bolts 1 through 8 in the numerical sequence to an angle of 180 ± 5 degrees. 6. Tighten bolts 1 through 8 in the numerical sequence to 180 ± 15 N·m (133 ± 11 lb ft). 7. Again, retighten bolts 1 through 8 in the numerical sequence to 180 ± 15 N·m (133 ± 11 lb ft) and turn an extra angle of 180 ± 5 degrees. Note: Tighten bolts (7) only after bolts 1 through 8 have been given the final torque. 8. Tighten bolts (7) to 55 ± 10 N·m (40 ± 7 lb ft).
