Hello,
Chevrolet unfortunately does not provide a specific torque sequence for the water pump (unlike the head gasket).
As a general rule of thumb, you want to firsthand tighten all the bolts. Then whichever bolt you torque first, you want to follow it up with the bolt that is across from that bolt and so on. That way you will put even pressure.
Also, these bolts need to be torqued in two steps. First at 11 lb. ft. then at 22 lb. ft.
I have attached the replacement procedure for your reference.
Let me know of any questions.
Thank you.
