n. a fluid agent (gas or liquid) that produces cooling; especially one used to cool a system by transfering heat away from one part to another; "he added more coolant to the car's radiator"; "the atomic reactor used a gas coolant"; "lathe operators use an emulsion of oil and water as a coolant for the cutting tool"
Wikipedia
A coolant is a fluid which flows through or around a device to prevent the device from overheating, transferring the heat produced by the device to other devices that either use or dissipate it. An ideal coolant has high thermal capacity, low viscosity, is low-cost, non-toxic, chemically inert, and neither causes nor promotes corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator.
While the term coolant is commonly used in automotive and HVAC applications, in industrial processing heat transfer fluid is one technical term more often used in high temperature as well as low temperature manufacturing applications. The term also covers cutting fluids.
The coolant can either keep its phase and stay liquid or gaseous, or can undergo a phase transition, with the latent heat adding to the cooling efficiency. The latter, when used to achieve below- ambient temperature, is more commonly known as refrigerant.
Usage examples of "coolant".

Pumps had no rotating parts and pushed the coolant through the loops using magnetism.
The ion exchange resin of the purification system, he knew, kept the radioactive particles in the nuclear coolant down to a minimum.
