Thermostat Removal 1989 420sel W126

THERMOSTAT REMOVAL 1989 420SEL W126

OK
So I flush the system yesterday, and remove the upper and lower hoses, to be replaced with new.
On to the thermostat.
1) Removed what I thought was the thermostat. WRONG.
2) OK found the thermostat to be located where the lower hose comes in below the pump.

3) HOW DO YOU GET TO IT AND REMOVE IT?

Please ASAP
It is nice this afternoon, and I skipped out on work to finish this up.
Thanks In Advance,
Bruce

either remove the alternator to gain acess, or use 1/4" sockets with 10mm sockets
