Orange antifreeze should not be mixed with green antifreeze because they are not compatible. If mixed together, these two types of antifreeze form a cloudy substance and precipitation that can decrease the coolant's useful life properties.Continue Reading
Although both the green and orange antifreeze are ethylene glycol-based, the difference between them is that they contain different corrosion inhibitor ingredients or additives. While orange antifreeze contains organic acids, green antifreeze has additives, such as silicates, borates and phosphates. The interaction of these different antifreeze types causes the formation of silicate precipitation, which has an impact on corrosion protection.
Another difference between these two antifreeze types is that orange antifreeze has a longer useful life that the green type. Orange antifreeze has a useful life of 5 years, whereas green antifreeze is good for up to 3 years. Orange antifreeze is referred to as an extended-life antifreeze.Learn more about Car Parts & Maintenance
Test the antifreeze in an automobile using an antifreeze tester. This device includes a squeeze bulb to pull antifreeze from the radiator, a cylinder with floating balls, and a tub to reach into the radiator. The number of balls floating in the liquid indicates the concentration of antifreeze in the coolant solution.Full Answer >
To bleed a radiator, fill the radiator and the coolant reservoir with a mixture of water and antifreeze, and run the engine with the radiator cap off until the air in the radiator escapes. Finally, refill the radiator and the coolant reservoir to the top, and replace the radiator cap.Full Answer >
The colors of antifreeze coolant are green, red, blue, yellow or pink. The color of antifreeze coolants varies depending on the manufacturer. Each color signifies a purpose in vehicle maintenance.Full Answer >
An automotive antifreeze chart has information regarding the amount of antifreeze necessary for various cooling systems at different ambient temperatures. For example, in a 12-quart cooling system, four quarts of antifreeze are required at 0 degrees Fahrenheit to avoid frozen water in the radiator, hoses or other parts of the system. Vehicles require larger percentages of antifreeze as either cooling system sizes increase or ambient temperatures decrease.Full Answer >
