Torque Specifications

Cylinder Head Torque And Sequence





NOTE: The cylinder head bolts should be examined BEFORE reuse. If the threads are necked down, the bolts should be replaced.

Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale (2), the bolt should be replaced.

Bolt Types




Sequence




If your bolt has the short head (1), use the following torque specifications:

Step 1: All to 30 Nm (25 ft. lbs.)
Step 2: All to 61 Nm (45 ft. lbs.)
Step 3: All to 61 Nm (45 ft. lbs.)
Step 4: All an additional 90°

CAUTION: Do not use a torque wrench for the Fourth step.

If your bolt has the long head (2), use the following torque specifications:

Step 1: All to 30 Nm (25 ft. lbs.)
Step 2: All to 73 Nm (54 ft. lbs.)
Step 3: All to 73 Nm (54 ft. lbs.)
Step 4: All an additional 90°

CAUTION: Do not use a torque wrench for the Fourth step.
