include anti-corrosion and anti-cavitation agents (that protect the hydraulic circuit from progressive wear).

Principles and history

Water was the original coolant for internal combustion engines. It is cheap, nontoxic, and has a high heat capacity. It however has only a 100 Kelvin liquid range, and it expands upon freezing. To address these problems, alternative coolants with improved properties were developed.Freezing and boiling points are colligative properties
