Radiator coolant is a necessary component in any engine cooling system. Coolant helps to regulate the temperature of an engine by transferring heat away from critical areas. It also protects the system against freezing and corrosion. There are many different types of radiator coolants on the market, but not all of them are created equal. The engine coolant is the liquid that circulates through the engine, into the radiator, and back into the engine. The antifreeze is a chemical compound used in engine coolant to reduce heat and the potential of engine coolant freezing. There are different types of antifreeze or engine coolant. Inorganic Acid Technology: Commonly known as In most cars and trucks, the cooling system works by circulating radiator fluid (a 50/50 mixture of coolant and water) through the engine, which will absorb the heat and cool the engine. Coolant also contains antifreeze. By having a coolant that runs through the engine block’s channels, the system stays regulated in both warmer and colder months. People are always asking what the difference is between radiator fluid vs coolant as well. It is essentially the same thing, the term coolant and radiator fluid is interchangeable while antifreeze is a different fluid that is added to the coolant mixture. Your radiator fluid or coolant can be with antifreeze or without. Antifreeze is a concentrated product, normally based on glycol and contains inhibitors, according to the AA. Some types have to be diluted with water to make them a suitable concentration before use, which is where the name coolant comes from. Coolant is a 50-50 mix of antifreeze (ethylene glycol) and water. Air conditioning refrigerant transfers heat from the cabin to the condenser. Engine coolant (or antifreeze, which is part of the coolant mix) does what its name suggests: it transfers heat from the engine to somewhere else (the radiator). Engine coolant uses water to transfer the heat produced from the engine combustion (burning fuel) to air Coolant, also known as antifreeze, is used to lower the freezing point of water and protect the engine from overheating. Windshield wiper fluid is designed to help clear away dirt, bugs, and other debris from the windshield for better visibility. Mixing the two can have dangerous consequences and cause major engine issues. So, to answer the common question: Is coolant and antifreeze the same thing? Not quite, but they are closely related. Antifreeze is aptly named for its ability to prevent freezing in cold temperatures. Yc2XHD.
