Yeah if I got this right, you're saying the specific heat (energy required to raise the temp +1º) increases with increasing pressure? If so that's completely right.
Thing is with a fluid like antifreeze (50/50 mix), the heat capacity would be so high and the differences in pressure (open vs closed radiator cap) would be so low that they may not be note worthy.
95% mad, 5% scientist.

That's pretty much how I imagined it. I remember on my last car the coolant expansion tank had a lid you could open with a hose on the top. One end transferred coolant and the other was open to the atmosphere. I literally know nothing about automotive cooling and I'd rather not take "educated" guesses at where exactly this system becomes closed if ever.
