FAQ:

Q: Why is coolant different colours?

A: Regular coolant is often green while DEX-COOL is orange or red. With respect to regular coolant, the green color is utilized to interact with rust and corrosion, letting you know visually when the coolant inside your vehicle needs to be replaced. Due to the orange color of DEX-COOL, it is harder to visually tell when the coolant must be replaced.

Q: What’s the difference between antifreeze and coolant?

A: While both are interchangeably used for car maintenance, there are various differences between the two. Firstly, antifreeze is one of the components used to create an engine coolant. Basically, a coolant is a 50-50 split of water and an antifreeze formula. Additionally, antifreeze is crucial for lowering the freezing point of engine liquids.

Q: What is the best radiator fluid?

A: Appropriate Type of Radiator Fluid. For most vehicles, a glycol based antifreeze coolant is the best type of coolant to be used in any vehicle radiator. However, using the glycol based antifreeze alone is usually not a good idea. In most cases, you will need to mix the glycol based antifreeze with a certain amount of water.

Q: Why is antifreeze different colors?

A: The color of antifreeze is generated completely by coloring dye, not as a direct result of any chemicals mixed during manufacturing. That said, different colors for antifreeze do exist. While specific colors agreed upon in the automotive industry do signify chemical makeup, variations still exist within each shade.
