To properly torque the head bolts on your 2015 Silverado 5.3, it is important to follow the recommended specifications. The table below provides the torque values in both foot-pounds (ft. lbs.) and Newton meters (Nm) for each step of the torque sequence.
| Step | Torque (ft. lbs.) | Torque (Nm) |
|---|---|---|
| Step 1 | 22 | 30 |
| Step 2 | 45 | 61 |
| Step 3 | 65 | 88 |
| Step 4 | 65 | 88 |
