Running hotter than before

[RAF7789]

ok so i reconnected the temp sensor and it appeared to be reading fine on the gage. but when i am driving for about 15 mins, the gage reads 210* which, i know is not bad. but before, i was alway on the left side of 210* no matter how long i was driving. i know there is not a bubble in the system, coolant has under 100 miles on it. i checked the radiator fins and there was a 2 or 3 quarter sized bends, but nothing extraordinary.

Well mine goes under 210 like to 170 when going down road. did you get on highway and see if it would go under 210
