What is the water pump bolt tightening sequence?
Nothing specific that I know of, just hand tighten and torque each one evenly at a time going across the pump to another nut till their all tight.
I could not find any tightening sequence either, so I would just pick a spot and do an alternating cross tightening sequence myself. Here is a great link for you with pics that you can print out if you want to, from the fordforums.com site. The 3rd and 7th postings should be of help to you. http://www.fordforums.com/f138/help-advice-water-pump-leak-173106/
