The coolants help to maintain a better temperature of the engine. It prevents overheating in summer and freezing in the winter seasons. The Green and Orange coolants are famous for the colors and flavors which effectively work on engines. They are available in online stores.

Key Takeaways

  1. Green antifreeze is made of inorganic acid technology, while orange antifreeze is made of organic acid technology.
  2. Green antifreeze is cheaper than orange antifreeze.
  3. Orange antifreeze has a longer life and better protection against corrosion than green antifreeze.

Green Antifreeze vs Orange Antifreeze

Green antifreeze, also known as traditional or conventional antifreeze, is made with ethylene glycol as the primary ingredient, along with various additives and corrosion inhibitors. Orange antifreeze, also known as extended life is made with a different type of primary ingredient, propylene glycol, along with different additives and corrosion inhibitors.

The green antifreeze is working on the concept of IAT( Inorganic Additive Technology). Phospate or silicones with propylene glycol or ethylene glycol the green antifreeze is composed.

This composition helps the metals inside to prevent rust and corrosion. The old aged cars like the cars in the 80s made with heavy metals and steel. The engine in old cars is needed pursy work which, leads to overheating. For that, green antifreeze is composed.

The orange antifreeze is for new cars. It works on the concept of OAT(Organic Additive Technology). The carboxylates are the vital component that prevents rust and corrosion.

The carboxylates do not affect non-metallic surfaces. The only aim of orange antifreeze is to protect the metallic plane from attrition. The coolant called Dex coolant is mixed with OAT to work more effectively.

What is Green Antifreeze?

Green antifreeze is a type of Inorganic Additive Technology (IAT). The silicates inside work on the metals to prevent corrosion and rust. The cars with heavy metals fitts with green antifreeze to erect cooling.

People misconnect the coolant with water. But coolants are different from water. They have separate Chemical properties that help to cool the engine. The cooling efficiency of cars is stable until the metals inside are pure.

The labor capability of the motor will increase with a decrease in cooling efficiency. It is created less toxic to humans. The green antifreeze is replaced with more chemicals to work more effectively every three years. The cars produced before 2000 uses green antifreeze.

The four-wheelers with heavy metals are used green antifreeze for cooling. It not only protects the engine but also provides cooling and prevents overheating. Anti-foam additives are present in modern engines. This Antifoam will prevent foam formation and gives better performance to the engine.

The car cooling system consists of metals in all parts. The metals might rub together and results in overheating. The green antifreeze contains propylene glycol and ethylene glycol that prevent the engine from overheating.

People living in colder climates may face freezing problems. The green antifreeze has silicates that prevent the engine from freezing in colder temperatures.

What is Orange Antifreeze?

The orange antifreeze is a type of Organic Additive Technology (OAT). Carboxylates are a vital component in organic antifreeze. The newly modeled cars have aluminum and nylon.

The orange antifreeze formulates to work on vehicles made up of aluminum and nylons. The additives used in orange antifreeze helps to prevent overheating and cooling. Carboxylates are inhibitors in nature. They can protect metals from rust and corrosion.

The carboxylates don’t coat the whole cooling system of the vehicle unlike, the silicates glaze the entire system of cooling parts in an automobile. It gives more life to the engines.

Global warming results in extreme temperature that makes the vehicles overheat. Modern technology has aluminum which, can be prevented by carboxylates. The orange antifreeze gives a better experience to the engines with fewer metals.

The carboxylates are unique because of their performance. It only reacts with metals and protects the metals from rust and corrosion. It doesn’t act with non-metal surfaces. Even at high temperatures, the carboxylates protect the metals in the engine.

The carboxylates protect metals by transferring the heat outside and extended the lifecycle. But it is not a good idea to mix the orange and green antifreeze. That leads to thickening of the consistency of the liquid and makes the closure of the water pump.

Main Differences Between Green Antifreeze and Orange Antifreeze

  1. Green antifreeze uses in old-aged cars, and orange antifreeze uses in newly modeled automobiles.
  2. Green antifreeze contains silicates, and orange antifreeze contains carboxylates.
  3. Green antifreeze is green in color, and orange antifreeze is orange in color.
  4. Inorganic Additive Technology is green antifreeze, and Organic Additive Technology is orange antifreeze.
  5. Propylene glycol in green antifreeze prevents overheating, and carboxylates in orange antifreeze are avert overheating.
