![]() ![]() In its purest form, the ethylene glycol color is a non-existent and viscous liquid that can be boiled at the temperature of 197° Celsius and can freeze at temperatures of 13☌ (8.6° Fahrenheit). In most cases, the proportion of ethylene glycol within the coolant can range from 50 to 60 %, which is enough to achieve the most efficient performance. Moreover, additives are also added for better visibility in the tank. The temperature at which the liquid boils is approximately +118° C (about 245° F).ĭue to the additives in G12 coolant, localizing corrosion takes place only in the required areas, forming resistant microfilms, which affect the corrosion foci. The freezing temperature is 50 ☌ below zero, or the temperature is -58° F. Its lifespan is about 4-5 years, and its density is 1.065 and 1.085 mg/cm3 (at 20 degrees C or 68 degrees F). ![]() G12 coolant has a red or pink hue and is based on carboxylate and ethylene glycol. Several coolants can be used for this purpose: G11, G12, G12 +, and G13.Īlso check: Does Coolant Affect the Air Conditioning? What is G12 coolant? This is where oil and antifreeze intersect in the same case. Some cars have a heat exchanger to control temperature. It also flows through the passenger compartment, where warm air blows when turned on. The coolant is contained in the engine’s closed jacket and line. Coolant’s primary purpose is to maintain the engine’s operating temperature in a particular mode. Its application has been limited to road transport. In addition to their excellent lubricating properties, propylene glycol-based coolant also has anti-corrosion and lubricating properties. These coolants can be found in modern cars that meet strict toxicity standards. Propylene glycol is an exciting new name in the coolant world. The poison can be neutralized by ethyl alcohol. The lethal dose for humans of ethylene glycol is 300 g. Its boiling point is around 200°,Īnd its freezing point at -12.5°. Regardless of its classification, the coolant contains either propylene glycol or ethylene glycol and its additive package.Įthylene glycol can be toxic. Coolant is the most common name for vehicle cooling fluid. ![]()
