My car tells me low coolant as well, but when stopped it doesn't go over 205 and thats sitting for an extended period of time. I have never seen my coolant over 207 I believe and when driving it sits pretty at 187-189. I have an 08 Turbo Cobalt with a front mount and running 1/2 e 85/ 1/2 93.

 

i drive around the city with temps between 192 and 203 im assuming this is normal when driving hard temps go down but the dash says low coolant but its full should i take my car in?

 

having this prob too on lnf after radiator cracked. jb weld ftw
