If the scale is in the elbow it will also be in the block. If I not mistake I do believe it is possible to flush the system. I don't know the exact details, but hopefully others will chime in. If not I'll do a search around the forums for a related topic.

would it be okay to heat the block around the plug to try and loosen it?? should I not bother trying to free it as I have read some horror stories about folks cracking the casting

I personally would do the minimum required to get the old thermostat out and the new one in unless you're having overheating problems, in which case the thermostat probably won't fix it because the scale and sediment are what's causing the problem.

To flush the system out, you basically open it up, stick a hose in the top and let 'er fly.

Be aware that it will never be completely clean. All you can do is flush out the loose stuff, and then only some of that because it settles into corners and gets caught in narrow passages.

Maybe you can get more out by filling the cooling system with a vinegar solution and getting the engine good and hot, then flushing.

in the owners manual it states -" that the practice of flushing the system by forcing water from a hose in the radiator filler neck, without the use of cleaning solutions, may only be a waste of time."" then it goes on to say to use the ih cooling system cleaner ,,,I know there is some debate on whether or not to use a flush product,,,seems like most say no.i was gonna use some I got from napa last year until advised against..wondering why manual states to?

Its because people believe that it will just break scale away and block passages. Which to be fair running straight water through under pressure will do the same thing. Its the same argument that pro non-detergent oil guys use saying deposits will come loose and block things.
