What is what color is coolant?

Coolant color is not an indicator of its type or quality. While there are general trends, it's more about the dye added by manufacturers for identification purposes.

Here's a breakdown:

• Green: Traditionally, green coolant was the standard ethylene glycol-based coolant used in older vehicles. However, modern green coolants with different formulations also exist.

• Orange/Red: Usually indicates Dex-Cool, an extended-life coolant often used in General Motors vehicles.

• Yellow: Typically a type of OAT (Organic Acid Technology) coolant.

• Blue: Commonly found in Asian vehicles (Toyota, Honda, etc.) and some European vehicles, but specific formulations vary.

• Pink/Purple: Often used in European vehicles, particularly those from Volkswagen/Audi.

• Universal/All Makes: These coolants are designed to be compatible with a wider range of vehicles and often come in yellow or clear colors.

Important Note: Never mix different types of coolant without confirming compatibility. Mixing incompatible coolants can lead to corrosion and damage to your cooling system. Always consult your vehicle's owner's manual or a qualified mechanic to determine the correct coolant for your vehicle. Relying solely on color is not a safe practice.
