Unlike the above commenters , congrats on a DIY job. The 7M engines do not need to disturb the timing belt or even the timing belt cover to get the water pump off, so I have no idea what that comment was about.

As far as the studs for the fan, the best way to get those out is to put two nuts on the exposed threads, tighten them together with two 10mm wrenches, then use the inside nut to unscrew the stud off of the water pump. I use the same method to install them on the new pump, using the outside nut to tighten the stud. I've used the same method on Ford's and Chevy's, as well as Nissan and other Toyota's.

Also, I usually do a flush before taking out the pump, and replace the radiator cap and thermostat while the system is drained. Cheap insurance.

Again, great job!
