You maybe using the wrong term for you description.
The higher you go in altitude the less oxygen is in the air; thus the term
thinner air.
I don't believe there is less volume of the mixture we call AIR. Nature
hates a vacuum so it fills in the spaces. There are differences in the
properties of AIR as the altitude changes.
With less oxygen you need to jet down a carburetor to get the fuel mixture
correct. You need to open the choke because less oxygen means it is
already choked. You need to gap your spark plugs correctly to reduce lean
misfires as you increase in altitude.
As you drive your car to higher altitudes the fuel mixture will become
richer; this should aid in cooling but altitude also decreases vapor
pressure which means the boiling point temperature drops. This could
equalize the altitude differences for the cooling system.
This is a good question. Is there a trip planned for your future to get
Rocky Mountain High?

Subject: question for all you rocket scientists
All,
This may be a stupid question and probably covered in the past but I have
not read anything related and those I have asked are not sure either so here
goes:
Two virtually identical cars (or the same car if it helps), one at sea level
and one at 6,000' elevation. 80 degree day in both locations, exact same
driving, exact same humidity, timing, tuning, etc. Will one car run cooler
than the other?
Basically I'm trying to find out what effect elevation and therefore thinner
air has on the cooling (if any) of a car. It strikes me that if there is
less air going through the radiator due to the thinner air then you would
have less cooling. Am I wrong or crazy?
Just curious,
Lynn, maybe the thinner air is getting to me
