Years ago, car radiators only had water in them, but these days, a radiator has a 50/50 mix of a glycol-based antifreeze/coolant and water. You don’t have to mix it yourself; the kind you buy in 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 Antifreeze is a liquid that's added to a car's engine cooling system. It stops the water from freezing under normal cold weather conditions. As well as lowering the freezing point, it also raises the boiling point of engine coolant. Along with a pressurised system, this helps to reduce the risk of overheating. 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 and antifreeze are referring to the same thing. It's called coolant because the primary purpose of that liquid is to cool the engine. It gets pumped through the engine and radiator, absorbing heat from the engine, cooling itself by exchanging heat with the air flowing over the radiator, then going back into the engine to absorb more If you say that antifreeze is a coolant, you might be right and wrong at the same time. Well, antifreeze and coolant are similar, but there's a difference. The former is a glycol-based fluid that must be mixed with water in the ratio of 1:1 for use. It is that antifreeze/water mixture that is called coolant. The major component in antifreeze is 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. Red and Pink are two different technologies, but are fully compatible. Red is good for 2-3 years/24k-30k miles, and Pink is good for 5y/50k with only the factory fill supposedly good for 10y/100k (when not poisoned with other coolants, or topped off with tap/well waters). When Red&Pink are mixed, use the 'lesser' interval. Freon removes heat from a car’s cabin, whereas coolant removes heat from the engine. Freon switches between being in a gaseous and liquid state, whereas coolant remains a liquid throughout its process. Coolant will not affect your A/C temperature. Freon will not cool your engine. Coolant contains antifreeze, unlike Freon. Radiator fluid is vital for preventing your car engine from overheating.Antifreeze is a type of fluid that helps lower water's freezing point. At the same time, car coolant also raises the boiling point.Both are important in hot and cold weather.Check your owner's manual to see what type of radiator you need. FOKBqgQ.
