As a responsible Subaru owner, you want to make sure that you are taking proper care of your vehicle, including its cooling system. One question that often comes up is whether it is safe to use green coolant in your Subaru. In this article, we’ll explore the differences between green and other types of coolant, the compatibility of green coolant with Subaru engines, and the pros and cons of using green coolant. By the end of this article, you’ll be better informed and able to make the right decision for your Subaru.
The Difference Between Green and Other Types of Coolant
Green coolant, also known as ethylene glycol coolant, has been used for many years in various types of vehicles, including Subarus. It is typically colored green and contains a mixture of ethylene glycol, water, and various additives that protect against corrosion and freezing. Other types of coolant include red/orange coolant (OAT/HOAT), which is typically used in newer vehicles, and blue/pink coolant (P-HOAT), which is a hybrid of green and red/orange coolant.
Is Green Coolant Compatible with Subaru Engines?
The short answer is yes, green coolant is compatible with Subaru engines. However, it’s important to note that Subaru recommends using only genuine Subaru coolant or an OE-recommended coolant that meets Subaru’s specifications. These coolants are designed specifically for Subaru engines and have been tested to ensure compatibility and performance. While some green coolants may also meet these specifications, it’s essential to do your research and make sure that the coolant you choose is approved for use in Subarus.
The Pros and Cons of Using Green Coolant
One of the benefits of using green coolant is that it is widely available and less expensive than other types of coolant. It also has a longer life span than some other coolants, so you won’t have to change it as frequently. However, as with any product, there are also some potential drawbacks. For example, green coolant can leave residue in your engine if it breaks down, which can cause clogs and other problems. It’s also more toxic than other types of coolant, so you’ll need to be especially cautious when handling and disposing of it.
Potential Risks of Using Green Coolant in Your Subaru
While green coolant is generally safe to use in Subarus, there are some potential risks you should be aware of. The first risk is that using an incompatible coolant or mixing different types of coolant can damage your engine. If you are unsure about whether a particular coolant is safe to use in your Subaru, it’s always best to err on the side of caution and stick with a genuine Subaru coolant or an OE-recommended product. Another risk is that using low-quality coolant can cause your engine to overheat or fail prematurely, which can be costly and inconvenient.
