- 1). Determine the torque specifications for your cylinder head. This information can be found in your vehicle's maintenance manual. You could also call a local mechanic, who likely has access to this information. The torque procedure will likely have multiple steps, all of which must be applied separately.
- 2). Apply the first torque to the center-most bolt.
- 3). Apply the torque to the two bolts to the right of the center-most bolt. Torque the top first, then the bottom.
- 4). Apply the torque to the two bolts to the left of the center-most bolt. Torque the bottom first, then the top.
- 5). Apply the torque step to the next set of bolts out to the right of the center-most bolt. Apply it first to the top bolt, then to the bottom.
- 6). Apply the torque step to the next set of bolts out to the left of the center-most bolt. Apply it first to the bottom bolt, then to the top.
- 7). Continue working outward in this fashion until you've tightened all bolts. The bolts to the right should all be tightened from the top to the bottom; the bolts to the left should all be tightened from the bottom to the top. This sequence -- called helical sequences -- ensures that the torque is applied evenly throughout the component.
- 8). Wait about 15 minutes after all bolts on the component have been torqued to the first measure. The bolts are actually a little elastic, and need time to stretch and settle before the next application of torque.
- 9). Apply the second step of the torque sequence to all of the bolts in the exact same order as you worked for the first step.

Repeat steps one through eight for the rest of the steps of torque application.
