Pictured: a sheared bolt. Story below.
Because I accidentally drained out some engine coolant when I took the old knock sensor off my truck, I decided to go ahead and flush it all out anyways since I don’t know when the previous owner last did it.
To that end, I pulled the thermostat covering off to remove the thermostat so the flush will go through the whole block. However when I put the driver side bolt back in, I discovered that I had cross threaded it
After trying in vain a few times to get it to go back in the right way, I have the brilliant idea to just try to torque it down anyways. Yeah.
I get it pretty close to all the way down in there, then start the engine up. Sure enough, there’s a small coolant leak from the thermostat. Nuts.
“Well,” I think “now I get to learn how to tap new threads.” I decide to back the bolt out to use as a reference for the tap to get... and it shears in two halfway through removal.
So, now I get to not only learn about tapping new threads, but also drilling out sheared bolts! Only problem is that my only drill sucks so I don’t know if it’ll be up to the task. Is this something you can do with a hand tool like you do when tapping threads? Or does it really require a good, very torquey drill?

If you pull the thermostat cover, is there a bit of the bolt sticking out you might be able to grab/weld a nut onto?
I’ve been in the same place, but front axle hub nut. the nut/axle wasn’t the same thread pitch or something was majorly wrong there, hadn’t checked the fitment before putting it on the car. Short discussion with the guy i was fixing the car for/with, out came the 3/4" breaker bar with extra iron pipe on and on with was cranked. I politely decline to ever have that car back in for any front suspension repairs now, lest i have to deal with getting that thing OFF again.

I had almost the same thing happen to me when I replaced my t-stat but it happened when I was removin g it for the first time. Luckil y there was enough of a stub sticking out of the block to get a set of vise grips on.

Broke one doing the thermostat on my Jaguar. Fortunately on that engine it’s on a water rail I could take off, though that was a lot of work and required flexing the rather crispy fuel injector harness more than I wanted.
The stub turned out to be lodged in the housing casting so I was able to just spin it off once there was room.
But despite much scary crunching sounds putting the injector harness back in it’s run fine ever since.

Ooh, yes! Unfortunately it is torqued in there pretty good and I don’t have a welder, but maybe I can get it out with vise grips

Nice! I do have a stud poking out but it is torqued in there pretty good so I don’t know if I’ll be able to get it out with a vice grip. I did pick up a big old 10 inch one from the hardware store since the only one I have is teeny. We’ll see if it can do the job.
