What Coolant to Use for 2011 Subaru Outback: A Comprehensive Guide

If you own a 2011 Subaru Outback, you need to know what coolant to use to keep your vehicle running smoothly. Coolant is essential to regulate the temperature in your engine and prevent it from overheating. Using the wrong type of coolant can damage your engine, so it’s important to use the correct coolant for your vehicle.

In this article, we’ll discuss the different types of coolant, how to check your coolant level, and what coolant to use for your 2011 Subaru Outback.

Key Takeaways

  • Using the correct type of coolant is essential to maintaining your engine’s health, preventing overheating and corrosion.
  • The 2011 Subaru Outback requires a coolant that is free of silicates, nitrates, and amines, such as Subaru Super Coolant or a high-quality aftermarket alternative.
  • It’s important to check your coolant level regularly and maintain the recommended mix ratio of coolant and water.
  • Always follow the manufacturer’s guidelines for coolant replacement intervals and flushes.

Types of Coolant

There are two main types of coolant: ethylene glycol-based and propylene glycol-based. Ethylene glycol-based coolant is the most common type and is typically green in color. It is highly toxic and can be dangerous to pets and wildlife if ingested. Propylene glycol-based coolant is less toxic and is typically orange or pink in color.

Subaru recommends using a coolant that is free of silicates, nitrates, and amines. These substances can cause corrosion and damage to the engine over time. Subaru Super Coolant meets these requirements and is the recommended coolant for your 2011 Subaru Outback. However, there are high-quality aftermarket coolants that are also compatible with your vehicle.

Checking Your Coolant Level

To check your coolant level, wait until your engine has cooled down and locate the coolant overflow tank under the hood. The overflow tank is typically translucent and has markings for minimum and maximum levels.

If the coolant level is below the minimum level, add a mixture of coolant and water to bring it up to the recommended level. It’s important to maintain the recommended mix ratio of coolant and water, which is typically 50/50. Too much water can reduce the effectiveness of the coolant, while too much coolant can cause the engine to overheat.

Coolant Replacement Intervals

Subaru recommends replacing the coolant in your 2011 Outback every 11 years or 137,500 miles, whichever comes first. However, it’s important to check your owner’s manual for specific guidelines for your vehicle. It’s also recommended to flush the entire cooling system every time the coolant is replaced to ensure that all old coolant and debris are removed.

Frequently Asked Questions

Q: Can I use any type of coolant in my 2011 Subaru Outback?

A: No, it’s important to use a coolant that is free of silicates, nitrates, and amines, such as Subaru Super Coolant or a high-quality aftermarket alternative.

Q: How often should I check my coolant level?

A: It’s a good idea to check your coolant level every time you check your oil level, which is typically every time you fill up your gas tank.

Q: Can I add water instead of coolant if I don’t have any coolant on hand?

A: If you need to add coolant and don’t have any on hand, you can add water temporarily, but it’s important to replace it with the proper coolant as soon as possible. Water alone does not provide the same level of corrosion protection as coolant.

Conclusion

Using the correct coolant is essential to maintaining the health of your 2011 Subaru Outback’s engine. Subaru Super Coolant is the recommended coolant for your vehicle, but there are high-quality aftermarket alternatives that are also compatible. Regularly checking your coolant level and maintaining the recommended mix ratio of coolant and water will help keep your engine running smoothly. Always follow the manufacturer’s guidelines for coolant replacement intervals and flushes to ensure the longevity of your vehicle.
