What color is Subaru coolant?
Subaru coolant is typically green in color. This green coolant is a mixture of ethylene glycol and water, with added corrosion inhibitors and dyes to give it its distinctive hue.
What is Subaru Coolant?
Subaru coolant, also known as Subaru Long Life Coolant, is the factory-recommended engine coolant for Subaru vehicles. It is designed to provide long-lasting protection against overheating, corrosion, and freezing in Subaru's boxer engines. The green color of Subaru coolant helps distinguish it from other types of coolant, such as the orange or red coolants used in some other automotive brands.
Why is Subaru Coolant Green?
The green color of Subaru coolant comes from the addition of dyes and corrosion inhibitors to the ethylene glycol and water base. These additives serve several purposes:
- Dyes: The green dye helps identify the coolant as Subaru-specific and makes it easy to spot leaks or contamination in the cooling system.
- Corrosion Inhibitors: The corrosion inhibitors in the coolant help protect the metal components of the cooling system, such as the engine block, radiator, and water pump, from rust and corrosion.
- Freeze/Boil Protection: The ethylene glycol in the coolant lowers the freezing point and raises the boiling point of the fluid, helping to prevent overheating and freezing in extreme temperatures.
The specific green color of Subaru coolant is a proprietary formula developed by the automaker to match their brand identity and provide optimal protection for their engines.
Importance of Using Subaru Coolant
It is crucial to use the correct Subaru-approved coolant in your vehicle to maintain the warranty and ensure proper cooling system performance. Using a different type of coolant could lead to compatibility issues, increased wear on components, and potentially even engine damage over time. Always refer to your owner's manual or consult with a Subaru dealer or certified mechanic to ensure you are using the right coolant for your Subaru model.
