Pump the brakes on the Dremel! I'm sure people will chime in, but you can do some damage in a hurry using power tools on that sealing surface, and you won't be able to easily undo it. There are more controlled ways to clean up your gasket mating surface by hand.Thanks everyone for the help. I was able to finally get the broken bolt out with some vise grips on the one thread that was still sticking out. My local Toyota dealer was not helpful in sourcing the bolts so I matched the original bolts at a hardware store. I’m not sure of the correct grade, but I bought grade 10.9. I can confirm the correct thread pitch on all three is 1.25.
Before I reinstall the water pump, I’m wondering if I should address the metal surface that the gasket attaches to in the photo below? It feels a bit rough and uneven. I also noticed a bit of rust. Maybe a light polish with a dremel?
