Well boys and girls, I think I nailed down my overheating problem.
I had a couple hours today so decided to get the radiator drained and old thermostat out so that when the new one arrives Thursday all I need to do is pop it in, refill and rebleed. I decided to take the old, known working one along with the new questionable one inside and do a little... experimentation...
New German one on the left, old Chinese working one on the right:
New, cold and with closed valve:
Old with closed valve:
To test, you put the thermostats in a pot of water and bring to a boil. Around 180F (80C) the thermostat valve should open:
Sure enough, the old valve opened:
And the new one didn't:
Needless to say I'll be testing the NEW new thermostat prior to installing, you'd be foolish not to (I was). It takes all of about 10 minutes to bring a pot of water to a boil to save yourself a ton of headache and a potentially overheated engine. Actually, I'm very relieved that this is all my issue likely ended up being. If the new thermostat had been good I'd have been a bit stumped.
