KIA Motors review: may I know what is normal temperature for optima k5 during warm up at every morning. from 0 bar or other reading. please advise. thanks

i am first hand owner for K5 optima and registration at july 2016. During i use that car, i has relief the water temperature is show 0 bar for every morning when i has warm up . But after i use about one year plus, the water temperature will show in 1 bar when i just start my car for warm up at every morning. Even after have replacement new unit from Kia Service center in plentong Johor Bahru (malaysia).
Other things, i also have informed to Kia service center about my behind left hand size absorber and computer connect cover below at steering have sound during cross over of yellow line which provide by JKR malaysia to slow down of speed .They have take action to tight up of absorber holder . but unfortunately still happening again .
Kindly give me some advise or what is actual solution to solve of it . Thanks
