You dont say where you are living...whats the outside temps...are you in South Texas or in North Dakota? theoutside temops will have some bearing on it too...In summer I run 200-210 on freeway here in Texas...at 80+_...in winter , 185-190....but when I run 200+ and come to a stop, it will climb for a bit until I get going again , = normal...220 would be ok...but i`d be worried if 230 and abv...

when I bought my car many items you describe were missing and it ran 220 -230 my first trip from Dallas to Houston , climbing in every up hill...but I improved several as[pects plus took off an extra 'helper' fan that was in front or radiator and only slowed air going thru....

this has been discussed many times before too, but i`d keep a T-stat in there, a 190....
