What is the correct method of setting the tension on a cylinder head bolt?

The correct method of setting the tension on a cylinder head bolt typically involves using a torque wrench to apply the manufacturer's specified torque value. The process often includes tightening the bolts in a specific sequence to ensure even pressure across the cylinder head. It may also require an initial torque followed by a further angle of rotation, depending on the engine design. Always refer to the vehicle's service manual for the precise specifications and procedures.
