Wow
If the hose has expanded that much it needs to be replaced for sure!
Regardless of the bleeding, that is a lot of pressure. To much pressure!
Why originally were you changing the thermostat?
I assume you put in a 180deg thermostat?
Having that much pressure could be a bad cooling system cap. Or possibly an indication of an internal issue such as a head gasket leak (I am dealing with similar on my 2002 D2)
As for bleeding, you need to bleed it from cold.
Pop the resivor out of its mounting clip and raise it as high as you can hold it without pulling on the hoses, fill with the bleeder cap loosened until you get a steady stream of coolant and no more air. Once you are comfortable you have all the air out close the bleeder and then re mount the Resivor.
Start and run the engine at idle with the resivor cap off, heater on full hot heat you should see a solid stream from the small hole inside the top of the resivior.
Monitor actual temperature DO NOT rely on the dash gauge. They register the same 150 to dam near 240 which is way too hot.
Temp should be under 190deg with a 180 deg stat and under 205deg with a stock stat.
Let us know what you see tomorrow.
