Broken water pump bolt removal

I would not use an EZ-Out to extract this bolt. Broken EZ-Out's are ten times more difficult to remove than broken bolts.

True, I had a broken trans cooler fitting that was broke off past flush on the case. Tried an EZ out and within couple turns that broke off also....... What to do?? So I fired up the tig welder and welded a Hardend Nut to the ez out. The ez out was past flush also so i had to build the weld up enogh and then weld the nut on. It came right out very easy with this technique. Then I took a very small file and filed the fitting in 4 places right to the threads, broke it up and it came out also. Cleaned it out good, chased the threads, thread sealer, new fitting, fixed. Trans was on an engine stand doing this fix.
