My facelift 2.2 runs at just over 70 degrees most of the time, rises to 85ish at end of hot run, climate works fine.
Reading these posts, do I assume this is normal or that my stat is stuck open? I have brought a spare with me in case of issues.
I will do the top hose test as noted on here later... 
Yup, should run close to 85 all the time.
Currently half way though doing mother tunnies 3.0 stat, give me a 4 pot to work on any day 
Just got this done this morning at a Polish garage, had stat on board, now runs at 85 degrees and heating much warmer.
Glad I did not do this myself as rubber gasket was determined to break free- they used a tiny amount of gasket sealant to keep it in correct place when mating housing and block, which I had not got.
Was an adventure going to Polish garage and conversing in my broken Polish and helping them do it-so I could do it next time. Cost 20GBP including German -52 red coolant to top up exisitng red-so very cheap and easy fix.
All the guys looked at the Omega and made positive comments-so a nice morning out
