'bout the only other answer I can think of (other than the ones already answered) is a small propane torch.
Because the ends of the bolts sit in a water/high temp environment, they tend to rust in place.
With the torch, heat the exposed part of the bolt, being careful not to damage the thermostat casting. This will expand the bolt, hopefully busting loose the rust bond.
After it has cooled, heat the block around the bolt, hopefully expanding the threaded hole the bolt is in.
NOTE: This is a "If everything else fails" method.
Things to consider:
You could ruin the thermostat housing, and then need a new one.
You are working a torch VERY close to a carburetor full of gas (if not fuel injection)
You might burn some wiring, hoses if not careful.

Heat! Heat! Heat!. Using the hot wrench will work. Very carefully heat the bolt . Let it cool a little and heat it again. Tap the bolt with a hammer, the shock will help break it loose.
Now use a 6 point socket ,3/8 drive with small breaker bar, it should come loose..
Kroil is the best penetrating oil I have used. Its available on line from KANO labs.

Soak the bolt head for 10 minutes in WD 40. Then if you havent already made the boltnut round by trying to get it lose. Use an open end wrench ( the ring side)and chock it lose. That is hitting the wrench with a hammer. Steady pressure mostly fails and causes busted nuckles.

Leverage is the answer,you will need to try a breaker bar and if the bolt snaps off then you will need to drill a hole in the center of the bolt and use an easy-out to remove the broken part.It is a pita but it works.

The most famous bolts for breaking off. Use a product called "Aerokroil" it's a penetrating lubricant that can seep into area's as small as 2000th of an inch.

I wound up having to buy a set of those things at Sears....I can't think of the name....bolt out maybe. I know what it's like with those damn bolts man. They can certainly be a ***** sometimes.

You can buy a device called an ease out...You can get it at most auto parts stores. It is for stripped or broken bolts.

spray with BLASTER penetrant from auto zone. if it breaks off, use a drill to bore a hole thru the center of it and use a EASY OUT tool. if this fails. drill the hole out large enough to use a THREAD TAP.
