Tightening Torques 4E-FE

When I work on a vehicle I always tighten bolts up in 2 stages if there are more then 3 bolts to tighten.

What ever the finishing Nm of torque is half it and do that first so for example if you have a rocker cover that the bolts tighten to 8Nm, tighten them to 4Nm first. After you do them to 4Nm up the torque to 8Nm and repeat the process.
