I think the key here is; "Liquids cannot be compressed."

If a given liquid (at normal ambient temperatures) is heated, it will
expand but remain in a liquid state hence, it has to go somewhere to
accommodate the resultant expansion.

In modern cars, this is the coolant reservoir while in the older tin of
the past, it was simply the space at the top of the radiator.

Liquid expansion indeed would be accommodated by hoses until the psi
equals and surpasses that of the radiator cap setting at which point,
coolant will flow into the reservoir.

As I stated earlier, a liquid cannot be compressed (volume-wise) but it
certainly can react to pressure, (boiling point etc.), so accommodation
must be provided for such expansion from temperature increases.

BTW, at around 39°F, water is at it's most compact physical volume.
Temperature increases/decreases will cause it to expand.

no, they're fiber reinforced so this /doesn't/ happen. or at least, not
to a significant extent at 13psi. otoh, you can argue that the metal
tubes in the radiator expand if you really want to get fixated on this
stuff.

but what we're discussing here simple thermal expansion, not boiling.
"expansion" when boiling is due to phase change - a whole different ball
of wax.

water is one of the few substances out there with weird anomalies in its
thermal expansion coefficient.

It turned out to be a leaking water pump. I believe the Grand Prize
goes to Tegger (or maybe Ray) for guessing that. I'm relieved. The pump
also had one frozen bolt, so I'm wondering if the pump really *was*
replaced 5.5 years ago and 50k miles ago, like th printout from the West
coast dealer said. It shouldn't have been in such bad shape - the
replacement interval is 6 years and soemthing like 80k miles...

Er, the entire structure expands as temperature rises... Engine,
radiator etc.

Um, I said "boiling point" as a yardstick that is subject to change
depending on how much pressure the liquid is subject to at the time.

But it does. ALL materials expand with heat.

The reservoir level naturally rises and falls as the coolant heats and
cools. This is the purpose of the various seals in the rad cap, and for the
very presence of the (unpressurized) reservoir in the first place.

You don't have to take my word for it. Check your own reservoir's level at
dead-cold. Drive the car to full-hot, then have another look at the level.
It will be at least a half-inch higher.

Coolant is constantly traveling in and out of the reservoir with every
heat-cool cycle. It's a normal and necessary feature of a modern sealed
cooling system's operation.

?? the average honda owner, meaning me, can see a rise of maybe an
inch or so in the reservoir after the engine is hot.

of course, the coolant at operating temp is quite a bit above the
"boiling point" of 212 degrees, that's why it's pressurized.
in other words, you've gone from about 500 fahrenheit degrees above
absolute zero, to about 700 degrees. as a first approximation, that's
gonna see a 40% expansion. i hope your hoses don't expand that much.

try driving up grapevine [california i5], in summer, at 95. i guarantee
you'll see more than that. unless there's something wrong, it won't
overheat, but fluid level will be right at the top of the bottle.

=======================

Yep. That's exactly what I said in the first place:

> I've owned six Hondas and the level in the reservoir never changes more than about 1", hot or cold, summer or winter.

Actually, the thermostat on most cars is below 212 F. And the boiling
point is above 212 with the antifreeze.

It's actually going to be about 4% from O to 80 c (about 180 F).

http://www.simetric.co.uk/si_water.htm

Coolant will expand by a different amount, because it has antifreeze and
other additives in it.

Solids don't increase by 40% in volume from -40 F to 212 F. Why would
you think water would?

wow. i stand corrected. my "estimate" obviously didn't include the
zero temp term,
i.e. if volume = A +B(absolutetemp) I was estimating that A = 0, which
obviously it doesn't.
