Frequently Asked Questions
What is the purpose of coolant color coding?
Coolant color coding is a system used to identify the type of coolant used in a vehicle’s cooling system. The colors are standardized across the industry and are used to indicate the type of antifreeze or coolant used. The colors serve several purposes, including making it easier for mechanics to identify the type of coolant used in a vehicle, ensuring the correct coolant is used for maintenance or repairs, and reducing the risk of using incompatible coolants that can damage the engine or cooling system. The colors are typically displayed on the coolant container, and they may also be indicated on the vehicle’s manufacturer documentation.
Why do coolants come in different colors?
Coolants come in different colors because they have different chemical compositions and properties. Each color corresponds to a specific type of coolant, such as green for ethylene glycol-based coolants, yellow for propylene glycol-based coolants, and pink for organic acid technology (OAT) coolants. The colors help to distinguish between coolants that are designed for use in different types of engines or cooling systems, and they can also indicate the level of corrosion protection or freeze protection provided by the coolant. By using different colors, manufacturers can ensure that the correct coolant is used for each vehicle, which helps to prevent damage to the engine or cooling system.
How do I choose the right coolant color for my vehicle?
Choosing the right coolant color for your vehicle depends on the type of engine and cooling system used in your vehicle.
