Possible BLOWN HEAD GASKET!!! BAD NEWS
And you should probably add water to it, that's what I would do, eating them without water can cause constipation.
Check to see if the drains from the sunroof are clogged. If they are rain water will pool and run into the car.
Consult a Local Transmission Shop
Yes, water would still be able to move freely within the container regardless of the air pressure, as long as the container can withstand it. The movement of water would not be restricted by the air pressure in this scenario.
Take a container with a rather precise scale and measure it. Place the ring inside and measure it again. The amount the water goes up is the volume of the ring. Or you could fill a container to the brim with water, with a collecting dish underneath. Put the ring in the container, which would cause some of the water to overflow. The volume of water that left the container is the volume of the ring. Or you could take a clay mold and make a mold of the ring, fill that with water and measure how much water it takes to fill the 3D mold.
The plastic water pump rotor may have stripped off the shaft.
a lot of things mostly a leak of some kind
You would need to use a container of water like a 5 gallon bucket and pour it into the toilet. As you pour it in, the excess water will cause the toilet to drain.
You add water to the container then you stir, the water and salt would form a solution and sand would settle on the bottom of the container. You get another container and place on a filter paper then you pour the water into it, which would lead to the sand staying in the filter paper and the solution, which is made of salt and water, would be left. Finally, you place the container on a source of heat which will cause the water to evaporate and salt staying in the container. Now weigh the residue and find the percentage.

This may be adequate for some applications. You can use different sized sieves and or filter papers to get to the next stage of purity. Reverse osmosis is a third technique used. Boiling and condensing the water (distilled water) would be another way.
Was it coolant? Possibly a leaking heater core.
