Coolants are used to reduce or maintain the temperature of the engine.Your car’s engine produces a lot of heat when it is running and must be cooled continuously to avoid engine damage, cause engine is a self destructive system.Most of the people are unaware of the importance and makeup of coolant that they use water instead of coolant.So lets discuss about this topic.Using water instead of coolant is not a good idea because water has a less boiling point (100°C)and high freezing point (0°C)when compared to a coolant . Apart from that water also has minerals in it (nowadays it has more contaminants also).Thus water is corrosive to mental parts that have come in direct contact with it.Using water in cooling system gradually cause sludge buidup thus blocking the system ,this in turn leads to engine overheating and thereby more serious issues.Being a heat carrying agent, the properties of the coolant will eventually brake down in the long run that is why it is need to be replaced.Coolants are categorised into three groups, namely Inorganic acid technology (IAT) organic additive technology (OAT) and Hybrid organic additive technology (HOAT). Coolants are available in a variety of colours but it has nothing to do with the characteristic of the liquid. Efficiency of a coolant is dependent on its concentration of MEG-mono ethylene glycol.Mono ethylene glycol is being used as an active ingredient in coolant.We can do a lot of experiments to check the MEG content in a coolant.The most effective test to know the meg concentration is done by using a refractometer.
