My old thermostat was literally broken when I took it out, so I removed the guts and put the round brass plate back in (to support the o-ring so it sealed well) for flushing.

I'm not familiar with the details of your thermostat, but many MBs use a bypass to circulate water in the block when the engine is cold. The thermostat has a disc that blocks the bypass as the thermostat opens. If you run the engine without the thermostat the coolant or what ever you have in there can circulate around in the block and not make it to the radiator.
The instructions are generic, so you got to pay attention.
