Loosing coolant from somewhere

Um, in my Toyota the expansion tank is open to the air and has an overflow port and the top portion of the tank is empty well past the Full mark for more than enough expansion and a buffer zone before spilling onto the ground. The radiator cap is pressurized and it's a 2018.

My Father in-laws Dodge Caravan has the same setup and it's a 2017.

Not all cars used the pressurized reservoirs even today.

Sorry you did, my bad, I read it wrong. My apologies. I'm listening to music at the same time and slightly distracted.

Had a mystery leak on my 5.3L. Turned out to be the water pump. Only leaked when it felt like it, then sprayed it where you couldn't see it
