What is the function of automotive antifreeze?
1 Answers
Automotive antifreeze serves the following purposes: 1. Provides freeze protection for the engine against low-temperature environments; 2. Prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block and cylinder head when parked in cold winter conditions; 3. Offers efficient heat dissipation. Also known as engine coolant, automotive antifreeze contains substances that lower the freezing point of water, allowing vehicles to operate in winter temperatures while keeping the cooling system from freezing. The composition of automotive antifreeze includes: inorganic compounds like calcium chloride, and organic compounds such as methanol, ethanol, ethylene glycol, glycerin, lubricating oil, and purified water.
