Yes I did. Pretty simple really.
1. After you get all the engine covers off and drain the coolant, you want to remove the coolant reservoir tank.
2. Remove the air inlets.
3. Remove the belt
4. Disconnect the dipstick tube. You aren't removing it, you're just moving it aside.
5. Remove the water pump pulley.....YOU DON'T NEED a special tool (SST), mine removed easily with just a socket and a pry bar or screwdriver to hold the pulley in place.
6. Remove the water pump. When you replace the pump, I would make sure you torque the bolts all in proper sequence. All the bolts have different torque specs. Lots of diagrams on google that will tell you the specs and sequence.
I also replaced all my hoses and all told, I think it took me about 2 hours (including refilling the coolant and purging the air), and cost me 75 dollars for the pump and hoses.
MAKE SURE YOU USE TOYOTA COOLANT. Or, you can also use Zerex Asian Formula coolant that you can find anywhere. But FWIW, Toyota coolant was only a dollar more per jug, so why bother?

Did you clear everything out of the way to check for deposits? I couldn't see any either until I did. The deposits were around a bolt at the top middle of the pump. If not, I guess I'd let it go and monitor how much you're adding before delving deeper into where it's going. Or just go ahead and replace the pump as a precaution and rule that out.
