The new spacer plate requires a new torque procedure for cylinder head bolts. There are two different torque procedures that vary based on the depth of threaded head bolt holes in the block.Tightening Procedure 1 ( 7N-1961 Head Bolt)
Engines that utilize a B series cylinder block require a 7N-1961 Head Bolt ( 216 mm (8.5 inch)).Note: The bolt length is measured from under the bolt head to the end of the bolt shaft.
Illustration 2 g06265576
Use the number in the illustration above to torque the bolts in the order that is required for this procedure.
Note: Apply clean engine oil to the bolt threads and underneath the bolt head before installation.
Torque bolts number 1 through 8 to 30 5 N m (22 4 lb ft).
Torque bolts number 1 through 8 to 145 15 N m (107 11 lb ft).
Retorque bolts number 1 through 8 to 145 15 N m (107 11 lb ft).
Turn bolts 1 through 8 180 5 degrees.
Torque bolts 9 and 10 to 55 10 N m (41 7 lb ft).Tightening Procedure 2 ( 236-0486 Head Bolt)
Engines that utilize an E series cylinder block require a 236-0486 Head Bolt ( 254 mm (10 inch)).Note: The bolt length is measured from under the bolt head to the end of the bolt shaft.
Illustration 3 g06265576
Use the number in the illustration above to torque the bolts in the order that is required for this procedure.
Note: Apply clean engine oil to the bolt threads and underneath the bolt head before installation.
Torque bolts number 1 through 8 to 30 5 N m (22 4 lb ft).
Torque bolts number 1 through 8 to 200 15 N m (148 11 lb ft).
Retorque bolts number 1 through 8 to 200 15 N m (148 11 lb ft).
Turn bolts 1 through 8 180 5 degrees.
Torque bolts 9 and 10 to 55 10 N m (41 7 lb ft).
