Remember, always check your car's manual when buying coolant or opt for a high-quality universal variant.
The main coolant colours are: Green and Blue Green and blue traditionally represented Inorganic Additive Technology (IAT) coolants. Antifreeze comes in various different colors, but their meaning has changed over the years. Here's what they mean.
Common Coolant Colors and Their Meanings Red Coolant: The Traditional Choice Red coolant, often referred to as organic acid technology (OAT) coolant, is a popular choice for many vehicles. It typically contains a blend of organic acids that provide excellent corrosion protection, especially for aluminum components. With so many colors and types of coolant filling auto store aisles, choosing the right one for your vehicle can seem overwhelming.
But each variety serves a purpose for different engines and climates. The rainbow-like array of colors, pre-mix ratios and dilutions, additives, and more can make selecting or even understanding the various types of antifreeze available today confusing. Choosing the right antifreeze or coolant for your vehicle is essential for a healthy engine and a well-performing cooling system.
With various formulas, colors, mixtures, and temperature specifications, not all. Color Coolant In the intricate ecosystem of automotive and machinery cooling systems, coolant composition remains a pivotal component that directly influences engine efficiency, longevity, and environmental impact. The complexity of selecting appropriate coolants, often simply referred to as "color coolant," goes well beyond superficial hue distinctions.
It encompasses a detailed understanding. The Chemistry Behind Coolant Colors The color of coolant is not merely a cosmetic choice; it often reflects the type of antifreeze used in its formulation. Different antifreeze chemistries offer varying levels of protection against corrosion, freezing, and overheating.
These chemistries are often indicated by the color of the coolant.
