Antifreeze:
Antifreeze is used in the coolant of a car. It is a special additive that is added to the coolant, which ensures that the fluid does not freeze at a temperature of 0 degrees Celsius.
In the garage, there are also meters available to check if the antifreeze level in the coolant is still adequate. Since this decreases over the years, it is advisable to refresh the total content of the cooling system if the control test shows a negative result. When fluid without antifreeze (like tap water) is used in the cooling system, there is a risk that when the water freezes and expands at 0 degrees (which can happen quickly in winter), it can crack the engine block. New coolant is resistant to temperatures of -20 to -25 degrees Celsius. (Sometimes even lower).
Pure antifreeze is called ‘Ethylene glycol, also known as Ethyl glycol’. It is very harmful to health if ingested. For adults, an amount of approximately 100 ml can already have deadly consequences.
