Edit: This is not the thermostat.
I was adding a bit of coolant to my 2013 Focus to top off the system, when I discovered the thermostat.

Are you sure that's not for pressure? Looking at that I can't see how that could be a functional thermostat.

No idea! Maybe it is just for pressure.
My bad!
Not the thermostat.
Pontiac Fiero has to be the easiest thermostat change. It's under a pressure cap and the thermostat has a handle on it. Remove cap, pull thermostat, insert new thermostat, replace cap, Bob's your uncle.
I changed the thermostat on my Jeep Cherokee over the weekend. The housing cracked, the gasket was the wrong type, it took two trips to Napa and a whole bottle of coolant was lost to the garage floor. Should have been under 5 minutes, took two days. Lesson learned, buy the Mopar kit!
DOH!!!!
BMW 3 series and Fiat 124s. While you will lose a lot of coolant, the t-stat is in the hoses. No bolts to break, no gaskets needed, just loosen the hoses, pull thermostat, insert new one, retighten hoses, and refill system
Anything with an aircooled engine?
Well if it doesn't exist, isn't it difficult to service it?
2.2/2.5 chrysler is right up front. Takes about 10 minutes and you can do it without disconnecting the hose.
Nissan Maxima 3.0 isn't bad either. I think it took me about 10 minutes, you have to disconnect the hose, but that is because the thermostat and the housing are one piece. Billet Aluminium at that! Beautiful. but also $130
EDIT: and now I can find them on Rockauto cast for $17....FML
Any small block GM product.
BMC A-series (spridget) 3 bolts, dont even need to remove the hose I think.

But the heat still doesn't work afterwards.

The thermostat on a VW is actually pretty much a pain in the rear to replace. There's the bi-metallic part below the cylinders that isn't too bad, but the linkages and flaps and such are a real hassle.
That's why most people remove the whole system instead of fixing it, and why by now most people have never even seen the parts installed.

Wrong on both accounts. Air cooled engines DO have thermostats, for the same purpose. The Corvair for example has two thermostats (little bellows that expand when heated), one controlling each of the coolant air exit doors in the bottom shrouds of the engine.
The thermostats are what helps the heat to work when it's cold. Of course not generally nearly as fast as water cooled engines.
Bellows, normal and blown:
Installation in lower shroud with door:
Bugs are supposed to have bellows controlling the fan inlet, but I think many where removed. I think the only thermostat the 911 has is for the oil, but then again, many have called it an oil cooled engine.
The Corvair thermostats are reasonably easy to replace, and not messy, just a lot of small bolts. Adjustment can take a bit of time if you are not lucky.
The Miata thermostat is pretty dang easy...
GM Tech4 (Iron Duke) engines in some 80s FWDs and Fieros.
You unscrew the filler neck on the engine and lift it out. Drop in the new one and put the cap back on.
Next easiest is probably whiteblock Volvos. Right on top, no need to remove anything, no coolant usually leaks out either.
Chevrolet Trailblazer I6 - not.
GM 6.2 Diesel, two bolts and its mounted high enough that you lose almost no coolant.
N/A Mazda rotaries are very easy. Top of the engine and only 2 bolts.
Ford Fusion with the 4 popper is about the worst I have ever done.
Anything 4G63, Powerstroke, Chevy V8s, have been easy.
Any old GM Straight six. Two bolts front and center.
2.4 Chryslers. Top of the engine same housing as the pressure cap.
EA82 Subaru, it's front and center. Remove two bolts, leave upper hose attached. Did it in less than 5 minutes.
