Using a bit of coolant

mine sits on 80-84c , I never see it hit 85 even when its 30+ outside

 

Will sit around 80 if everything is healthy

 

Well I don't see a problem with my car or the cooling system and it sits at 90.

I am open to looking into trouble shooting it if there is a possibility of a problem being there, but it runs fine at 90 and it's definitely not a dangerous level. It runs at 85 on a cool day. What would you be checking if you were me? Both engines ran at 90.

Fwiw, as far as I know, 90 is considered to be a fine operating temp amongst most cars and I am almost certain that on the pexcom site it says that 90 is fine.
