Wouldn't a stuck open thermostat cause it to run cool, not hot?
The radiator cap seems to be providing pressure (if I release it slowly while hot, steam comes out as I release the spring).
I was also thinking that about testing the thermostat. Why go through the trouble for such a cheap part? Is there any difference between the $7 and $13 one? I'm not looking to save money on such a cheap part, but I'm just curious.
