An additive that lowers the freezing point of a liquid
Any of several substances (typically ethylene glycol) mixed with water and added to the car's cooling systems to prevent freezing of the coolant in winter. It also inhibits formation of rust and other deposits that would tend to clog the radiator and coolant passages, thus reducing cooling efficiency.
Antifreeze protects the cooling system against both freezing and boiling over. When used at normal strength (50% antifreeze, 50% water), it can lower the freezing point of the coolant to -34 degrees F. and raise its boiling temperature to 276 degrees F. N
A chemical that keeps water from freezing, often used in car radiators.
a PG based automotive coolant
A chemical solution that lowers the freezing point and raises the boiling point of the engine coolant.
Solution in an engine cooling system that lowers the coolant's freezing point and raises its boiling point.
A glycol (usually ethylene glycol or sometimes propylene glycol) mixed with water and an additive package used as a heat tranfer fluid in engines. By using an appropriate ratio of glycol to water, effective protection is provided against cold weather freezing as well as boil over under hot conditions.
A liquid added to the water in the cooling system of a vehicle to lower its freezing point, raise the boiling point as well as prevent corrosion.
A chemical mixed with the water in the cooling system to lower the temperature at which the coolant freezes, and in modern cars to prevent corrosion of the metal in the cooling system.
See Freeze/thaw stability controller
Something that helps prevent freezing. Some plants and animals use natural antifreezes during the winter.
A substance (ethylene or propylene glycol) added to the coolant to prevent freezing in cold weather.
a modifying agent added to water in a closed-loop system to lower the temperature at which the water freezes.
A greenish-yellow chemical used to keep your engine at a normal operating temperature. It is usually mixed with water and circulated throughout your engine by a water pump to keep the engine from boiling as well as freezing. Most antifreeze also prevent rust and lubricate moving parts in the cooling system.
Substance with a lower freezing point than water added to a liquid in a cooling system, such as an automobile, to prevent freezing.
Antifreeze is a water-based liquid coolant used in gasoline and diesel engines. Compounds are added to the water to reduce the freezing point of the mixture to below the lowest temperature that the engine is likely to be exposed to, and to inhibit corrosion in cooling systems which often contain a range of electrochemically incompatible metals (aluminum, cast iron, copper, lead solder, etc.). The term 'colligative agent' is to be preferred as, in warm climates, the benefit of these compounds is to increase the boiling point of the coolant, which should then be more properly referred to as 'anti-boil', and as anti-freeze decreases and increases both properties, respectively, 'colligative agent' more accurately describes the liquid.
