Yes, use the lower end if you're nervous over the torque. I pulled my instructions for the Edelbrock 8805 aluminum water pump and they make no mention of the torque at all. They do remind you to put the little overflow hose on first though.

You know, if it hasn't been drained in 12 years I might just drain it and replace it with fresh coolant again at the end of the summer.
