Coolent and Oil temp.

Not realistic behavior of oil and coolant temps,

Once you drop throttle temps will go down even when spit has thermostatic vales for oil and coolant.

That one for coolant will cut off radiators at 80C. So it should hold that temp even when you cut throttle completly. not for forever but in DCS temp drops like rock.

In coold weather you cant even get minimum coolant temp in spit.

I dont belive that heat will radiate throught engine block that quick.
