Glycerin-based formulations create coolants that balance protection needs of engine:

.-40°C freeze resistance: Prevents coolant from solidifying in frigid climates.

.108°C boiling point stability: Keeps coolant from overheating in high-temperature.

Beyond temperature control, glycerin-infused antifreezes also integratecorrosion inhibitorsto shield engine components  from rust and degradation — extending the lifespan of both the coolant and the engine itself.
