Antifreeze vs. Coolant: How They Differ. Antifreeze and coolant are similar in many respects, and they share the same purpose. However, they are not the same. Typically, antifreeze consists mainly of ethylene glycol, an ingredient that has an extremely low freezing temperature. COOLANT/ANTIFREEZE. Antifreeze is one of the components of a coolant mixture (coolant is generally a 50/50 mixture of antifreeze and water). Antifreeze is used to lower the freezing point and raise the boiling point of the liquid that circulates around the engine of a vehicle. This helps prevent the engine from freezing during cold weather. I’ve also read claims of racers using 100 percent anti-freeze because of its 387 degree F. boiling point. The problem with this approach is that the specific heat of straight anti-freeze is 0.66 as shown in the accompanying chart. According to the above referenced site, the cooling system has lost 20 percent of its capacity. Not much, actually. Antifreeze, usually ethylene glycol, does not freeze easily. It also does not boil easily. When it is added to water, it becomes coolant. You can buy it separately and add it to the water in your radiator—usually aiming for a 50 percent antifreeze to 50 percent water ratio—or you can buy it premixed, generally in that The short answer is no, radiator fluid and coolant are not the same thing. Coolant Coolant is also made up of water and antifreeze, but it has different proportions than radiator fluid. Coolant has more antifreeze than water, which makes it better at withstand high temperatures without freezing. Coolant also contains corrosion inhibitors that One says coolant and the other says antifreeze. So, is there any difference? Well, in reality, there is none. Both of these solutions are pretty much the same thing. So, you should not get alerted and confused if you notice this when purchasing coolant for your car. A jug of antifreeze will do the trick just fine. The freon will also be between a gaseous and a liquid state, and the coolant will remain as a liquid throughout time. The coolant will not also affect the temperature of your A/C. Freon also does not cool your engine, and the coolant contains antifreeze, not the same as Freon. Both of these fluids must also be replaced at different intervals Is antifreeze the same a radiator fluid? Not quite. Anti-freeze is the undiluted liquid that you mix with water (usually 50:50). The proper term for the mixture is "Coolant". Coolant. Shop All Coolant; Coolant (Anti Freeze/Anti Boil) Cooling System Water; Back Engine Oil.
