Does antifreeze float or sink in water?
A: Maybe, but keep in mind that antifreeze is heavier than water, and it will seek the lowest level in the pipe. If your main drain pipe has a steady pitch, as many do, you may notice the antifreeze coming out of the main drain, into the pool shortly after adding it.
Does antifreeze separate from water?
Ethylene glycol is completely miscible with water in all proportions (as the commenters point out). Therefore, once mixed, the glycol will not separate from the water, ever. The only exception is if it gets so cold the mixture starts to freeze.
What happens when you add water to antifreeze?
Water freezes at 32 degrees and boils at 212 degrees. When water is mixed with antifreeze (which is made of a chemical called ethylene glycol), the freezing point is bumped down to -35 degrees, and the boiling point raised to 223 degrees Fahrenheit. This makes ethylene glycol the perfect additive to our cooling system!
How much does a gallon of antifreeze weigh?
Antifreeze (ethylene glycol) in a 50/50 mix with water is freeze resistant to -34°F and weighs 9.4 pounds per gallon.
Why do sticks float?
Wood that is less dense and floats has big openings. Wood that sinks has very tiny openings. The ratio between weight and volume is called density. An object that is less dense than water can be held up by water, and so it floats.
How do you remove water from antifreeze?
To flush with water and remove any leftover residue from the old coolant/antifreeze, top up the radiator with clean water using a hose, and replace the radiator cap. Then, start the engine and leave it running for 15 minutes.
How do you separate water from coolant?
RE: Removing antifreeze from water You’ve got a choice, you can either separate it by distillation based on boiling points. or you can run it through an ultrafiltration system and separate it based on molecular size.
What happens when ethylene glycol is mixed with water?
Pure ethylene glycol freezes at about −12 °C (10.4 °F) but, when mixed with water, the mixture freezes at a lower temperature. For example, a mixture of 60% ethylene glycol and 40% water freezes at −45 °C (−49 °F). Diethylene glycol behaves similarly.
How does antifreeze work when water freezes?
Well, when water freezes, it expands and crystallizes. If we add chemicals to water, however, the molecules will have to work harder to join together and crystallize. Their struggle results in a lower freezing point. So in the end, inexpensive water and functional coolant form the perfect pair.
Can a coolant reservoir be filled with antifreeze?
During the night, can the antifreeze settle to the bottom of the cooling system, thus leaving a weak mixture of water and antifreeze within the coolant reservoir up top, where I take a sample with the refractometer? No. The only way for any separation to occur would be if some of the coolant froze.
How does concentrated antifreeze work in a car?
Concentrated antifreeze as the name suggests does not have water already mixed with it from the factory. Concentrated antifreeze consists mostly of a chemical ethylene glycol which is then mixed with water before being added to the cooling system of the vehicle.
When does antifreeze go bad in a container?
This is why concentrated antifreeze doesn’t have an expiration date. So if you keep antifreeze in its original container with a lid on top it will be as good as new after years ready to be put inside your car’s cooling system. But if you have a container of premixed antifreeze that comes mixed with water then it is going to go bad after 3 years.

Which is the best antifreeze for freeze up?
In fact, pure antifreeze will freeze at a temperature not much below where water does. In the coldest climates, the most effective mixture against freeze-up will consist of 60-70% antifreeze (with the rest being water) – not 100%.
Do you run only water with straight antifreeze?
The amount you should run depends entirely upon the likelihood of encountering cold weather. If it’s always 100F where you are (day and night), you should run only water (with water wetter). I have been using straight antifreeze for the last 10 years.
