What happens to antifreeze when it freezes?
If the coolant in your system freezes, it will seize up your system. It can also cause cracks in the system lines due to the coolant expanding as it freezes. If the coolant gets too hot, it can damage your engine, cylinder head and block.
Does antifreeze gel up?
It will gum up everywhere. When you shut it down due to it over heating, the substances are usually mixed, and it gels up into a hard jello like substance everywhere there is coolant. Everywhere from your Radiator to heater core, and of course, the engine block.Dec 6, 2015
What's the difference between coolant and antifreeze?
Though coolant and antifreeze are often used interchangeably, they aren't the same. Antifreeze is made of ethylene glycol or propylene glycol and is the basic ingredient, but it has to be mixed with water to create coolant, which is the cocktail you will find in the cooling systems of all “water-cooled” vehicles.May 30, 2021
How cold is antifreeze good for?
If it is mixed correctly (a 50/50 mix of antifreeze and water is ideal), the ethylene glycol can keep your radiator fluid from freezing even in temperatures reaching as low as 30 degrees below zero and also keep those fluids from boiling in temperatures reaching as high as 275 degrees Fahrenheit.
How do you know if antifreeze is frozen?
Car engines require a constant flow of coolant/antifreeze to keep them at their optimum working temperature, even on the coldest winter mornings. If the engine overheats, this could indicate that the radiator has frozen and coolant/antifreeze isn't circulating as it should.

Understanding Burst Points
The burst point is less understood. This was originally devised by plumbers in the 1930s to confirm at what stage a copper pipe would burst.
How Does Antifreeze Work?
When water freezes, H2O molecules surrender heat and become less active. Molecules stop moving around freely and settle into a solid formation. Scientists refer to this formation as a crystal lattice.
The Antifreeze Theory
During the nineteenth century, French scientist Francois Raoult concluded that the freezing point of water lowers in correlation with the number of molecules dissolved in the water.
The Antifreeze Journey
Engine Coolant is pumped through the engine, where it absorbs heat. As it passes through the radiator, it dissipates heat to the outside air. Antifreeze travels around the engine continuously. When it is old or contaminated, it needs to be replaced — usually around once every two years.
