With pure MEG (mono-ethylene glycol) the hot spot will reach 200 C (392 F). Cooling by other effects such as air draft from fans (not considered in pure nucleation analysis) will assist in preventing large-bubble formation.
The mixture of ethylene glycol with water provides additional benefits to coolant and antifreeze solutions, such as preventing corrosion and acid degradation, as well as inhibiting the growth of most microbes and fungi.
