If you’re finding clogged cooling lines I’d assume the sending unit did it’s job and is working fine. I wouldn’t worry about checking the resistance (you would have to cut the wires or get into the box behind the engine which is not the easiest area to work)

Sounds like you are trying to get the muffler expansion chamber off? There are alignment dowels so you need to pry it apart at the little tabs about a 1/4” before you can remove. The gaskets stick together so it might take a bit of force...but it won’t twist out because of the dowel pins...you need to pry the two parts away from each other.

Most of the major engine/exhaust parts have alignment dowels and tabs to pry them apart.
