been my experience that you need to establish what is normal for your truck.

Best to start as suggested, fill to the cold line after a cold soak and see what it does

Same with the oil dipstick. They are all over the place on where the full line is.

 

I looked at it today and cold it’s below the minimum line . When hot it’s barely over the minimum line . I looked in the book and it call for MotorCraft Yellow predeluted antifreeze/coolant. What I have in my truck looks like a greenish color. Anyone know if it’s a green tinted color or more yellow ? Part number says MotorCraft VC-13DL-G

 

Yellow mixes with the older orange. I thought the 20's came with the yellow already. Maybe not.

 

Our 2019’s OM indicates the MIN and MAX lines define the nominal range for cold coolant.

Yep I need to add a little and watch it .
