Ethylene glycol - Wikipedia
Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol [7]) with the formula (CH2OH)2. It is mainly used for two purposes: as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an …
Tech 101 – the colors of antifreeze - Hemmings
2014年8月1日 · Ethylene glycol is its base chemical and there are silicate and phosphate additives that make it compatible with copper, brass, cast iron and aluminum cooling system components. Manufacturers recommended that you change the green IAT antifreeze every 36,000 miles or three years.
1Color is fluorescent yellow, color may appear to be greenish/yellow when looking down into a bottle or drum 2Nitrites are required for some diesel engines 3Check your owner’s manual for specified service interval and antifreeze usage 4SCA should be tested and used at preventative maintenance schedules to keep nitrites at acceptable levels
What Does Antifreeze Color Mean? - AutoZone
Using the wrong antifreeze color can damage your engine by causing overheating, freezing, and corrosion within the cooling system.
Types & Colors Of Antifreeze - O'Reilly Auto Parts
Coolant is a mixture of antifreeze and water, whereas antifreeze is a pure mixture of either propylene glycol or ethylene glycol. Antifreeze should always be diluted with water, which is why pre-diluted or 50/50 antifreeze exists to help you achieve an …

2024年7月20日 · Ethylene Glycol: The most common base for engine coolants, providing excellent freeze and boil-over protection. IAT (Inorganic Additive Technology): Traditional technology using silicates and phosphates for corrosion protection.
Orange vs green: coolant basics you need to know - Autoblog
2009年12月27日 · The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no...
Propylene Glycol Vs. Ethylene Glycol - Go Glycol Pros
While dye color may differ by supplier, DOWTHERM SR-1 Inhibited Ethylene Glycol is fluorescent pink in color with an operating temperature range of -60°F to 250°F (-51°C to 121°C) and provides freeze protection to below -60°F (-51°C) and burst protection to below -100°F (-73°C) depending on concentration. Due to its moderate acute oral ...
Understanding the Different Types (and Colors) of Coolant - Car …
2023年9月29日 · Ethylene glycol became the new antifreeze of choice for combustion engines. Ethylene glycol has about one half the specific heat value of water. Thus when added to water the amount of heat a given volume of this coolant mix can retain is reduced. Cooling systems must circulate higher flow rates of this coolant to transfer the same amount of ...
Antifreeze Buying Guide: Choosing the Right Coolant - AutoZone
Generally, there are three coolant chemistries that each will fit into. They include: IAT coolant. Your conventional, green coolant that many DIYers are familiar with is known as an Inorganic Additive Technology, or IAT coolant. The base fluid is ethylene glycol, containing corrosion inhibitors that are considered not organic, such as silicates.
