Righty loosey on a 10mm bolt...

If you remove the other bolts it looks like that plate should come off. Then you might be able to flatten the broken bolt enough to drill it. Are you saying it has left hand threads? You can use this kind of extractor: https://www.summitracing.com/parts/...MIoKf50eiS_QIViBTUAR0FLwo0EAQYBSABEgKcq_D_BwE
No I just mean it snapped while tightening it, it's just a regular bolt, although it's way below that plate, sorry picture doesn't show the angle.
Aren't the 2 other bolts enough?
As noted take the plate off. Then try and grab the reminder if the bolt with a Vise Grip.
Is that a water pump? It might be easiest to just replace it, and let the rebuilder worry about extracting that broken piece from your core. Drilling out a jagged, broken, recessed bolt is near impossible in my experience.
If the head just snapped off when tightening, it might be loose enough to back out with a pick tool.
Looks like a power steering pump.
Remove plate, mig weld nut to broken bolt.
Probably, but I don't like that.
There won't be enough as this is way below the plate.
Power steering pump
Remove plate, use the appropriate size EZ Out bolt extractor
My experience with those things is they break in the hole and now it's 10X as hard to get out.

This, I have seen it work with my own two eyes. My kid did it for me.
Yes it is. But below the level of the pump housing?
Exactly. Center punch as best as possible, then drill with a left-hand bit.

Remove plate and see what you have to work with.
Pretty much any of the above already mentioned are workable options.
IrwinHanson, along with their competitors, extractor would take that out. Might have to use a dremel to smooth it up some before a center punch. I just don't see any problem here.

A lot of you are giving the false perception that it is easy to drill this out without damaging the threads. It isn't. This looks like one of the easier ones, but it is still tricky.

Good disposal option for drilling such holes.
Use a LH drill bit. Take something of the appropriate OD to someone with a lathe and have them thru-drill, say 1/8" or 3/16"
Now you have a centering jig to set in the plate and guide your pilot hole. Once you've got a start you can keep stepping up with LH bits, just don't exceed the minor dia of the threads.
Don't use an EZ Out. Ever. They're brittle and they snap and too hard to drill so then you enter wire EDM territory
The welded nut approach is also a good one.
Honestly if you just took the whole thing to a machine shop they'd probably have it out in 15 min, with most of that time spent devising a way to hold it on a mill table/in a mill vise
