What coolant to use on a Subaru?

When it comes to maintaining your Subaru, using the right coolant is crucial for the health and longevity of your vehicle's engine. Subaru recommends using a specific type of coolant that meets their strict specifications to ensure optimal performance and protection.


Subaru Coolant Recommendations


Subaru recommends using a Subaru Super Premium Long Life Coolant or a Subaru Genuine Coolant. These coolants are specifically formulated to meet Subaru's requirements and provide the following benefits:



  • Excellent anti-corrosion and anti-freeze properties

  • Compatibility with Subaru's engine materials and components

  • Extended service life, typically up to 100,000 miles or 10 years

  • Optimal heat transfer and cooling system performance


Using a non-Subaru approved coolant may result in compatibility issues, reduced engine protection, and potential damage to your vehicle's cooling system.


Coolant Maintenance and Replacement


Subaru recommends changing the coolant at the intervals specified in your vehicle's maintenance schedule, typically every 30,000 miles or 30 months. It's important to follow these guidelines to ensure your Subaru's cooling system remains in optimal condition.


When replacing the coolant, always use the recommended Subaru Super Premium Long Life Coolant or Subaru Genuine Coolant. Mixing different types of coolant can lead to compatibility issues and potential damage to the cooling system.


By using the correct Subaru-approved coolant and following the recommended maintenance schedule, you can help ensure your Subaru's engine stays cool and protected, extending the life of your vehicle.
