Would liquid nitrogen freeze antifreeze?

Yes, absolutely. The major component of antifreeze is usually either ethylene glycol, which has a freezing temperature of -12.9 ºC, or propylene glycol, which has a freezing temperature of -59 ºC. Nitrogen has a boiling temperature of -196 ºC. read more

The major component of antifreeze is usually either ethylene glycol, which has a freezing temperature of -12.9 ºC, or propylene glycol, which has a freezing temperature of -59 ºC. Nitrogen has a boiling temperature of -196 ºC. This means that even pure antifreeze, undiluted with water, would freeze in contact with liquid nitrogen. read more
