Thermostat housing bolts to what..

[TapShot]

Hey guys, so i want to know what the thermostat housing bolts to.
The thing is that i was trying to fix the thread where the three bolts go, but apperently the drill bit broke and its flushed into the hole, so if i take out the intake manifold, and say i take out the heads... Can i take that part off or is it the whole block.

The thermostsat housing bolts to the front of the lower intake manifold.

How were you trying to "fix the thread"? Did you cross-thread one of the bolts and you broke the bolt trying to re-thread the hole with one of the bolts?

You can get either counter-clockwise drill bits or bolt-out extractors to try and grab and spin it out, or sometimes using a small cobalt drill bit, you can drill into the center of the broken bolt, and then go up one more size (still smaller than the bolt itself), so you drill out the center of the bolt, then either use a counter-clockwise drill bit/bolt-out extractor and hopefully it comes out even easier, or sometimes if enough of the center part is gone, you can pull the remaining bolt threads away from the threaded manifold surface.

Pulling the lower manifold is an option, but you should be able to remove the serpentine belt, tensioner pulley, and maybe the alternator and bracket, and perhaps the radiator, and have better access to the area, without having to pull the upper and lower manifolds just to get a bolt piece out.

Thanks guys, il see if that helps...
My dad had the idea to take that piece out to take it into a machine shop or something. Bt il try that myself, thanks again.

The worst case scenario if you can't fix it, is to go to a junkyard and pick up another lower intake.

From someone who has to do things like that (not on engines, however) fairly often, be sure your drill bits are very sharp and take your time. It will work.
