What is the torque settings for a cylinder head on a vauxhall vectra 19cdti?

For a Vauxhall Vectra 1.9 CDTI, the cylinder head torque settings typically involve a sequence of steps. Initially, the bolts should be torqued to around 20 Nm (15 lb-ft), followed by an angle tightening of 90 degrees, and then an additional 90 degrees. It's important to follow the specific torque sequence to ensure even pressure across the cylinder head. Always consult the vehicle's service manual for the most accurate specifications.
