Can I put Prestone coolant in my Subaru?
The short answer is that it is generally not recommended to put Prestone coolant in a Subaru vehicle. Subaru engines are designed to work best with the specific coolant recommended by the manufacturer, which is typically a different type than Prestone. Using the wrong coolant can potentially cause issues with the cooling system and engine performance.
Understanding Coolant Compatibility
Automotive coolants are formulated with specific additives and properties to work optimally with the materials and design of a vehicle's cooling system. Subaru, like most automakers, specifies the type of coolant that should be used in their vehicles. This is typically a long-life, ethylene glycol-based coolant that meets Subaru's own engineering standards.
Prestone, on the other hand, is a universal coolant that is designed to be compatible with a wide range of vehicles. However, it may not contain the exact same additives and properties that Subaru's recommended coolant does. Using Prestone in a Subaru could potentially lead to accelerated corrosion of cooling system components, reduced heat transfer efficiency, and other issues over time.
Recommended Coolant for Subaru Vehicles
Subaru recommends using one of the following coolant types in their vehicles:
- Subaru Long Life Coolant
- Genuine Subaru Coolant
- A coolant that meets the Subaru specifications of ASTM D3306 and D4985
These coolants are specifically engineered to work with Subaru's cooling system design and materials. Using the wrong coolant could potentially void the vehicle's warranty and lead to more expensive repairs down the line.
Conclusion
In summary, it is not recommended to use Prestone coolant in a Subaru vehicle. Subaru engines are designed to work best with the coolant specified by the manufacturer, which is typically different from a universal coolant like Prestone. For the best performance and longevity of your Subaru's cooling system, it's important to use the recommended coolant type.
Is it OK to use Prestone coolant?
It can be used in all cars effectively, offering the same levels of protection, and without any damage. We offer a guarantee that Prestone is suitable for all cars and engine materials.
Can wrong coolant damage thermostat?
Corrosion occurs, among other things if a wrong coolant is used. The corrosion attacks the thermostats aluminum parts that almost "etch away" (see figures 1 and 2). But also mixing of different coolants can cause corrosion. Therefore avoid mixing different types of coolant together.
What color coolant does Subaru use?
The coolant that subaru uses is Long Life Super Coolant and it is blue. It is rated for something like 150k miles before needing a change.
Can you add Prestone to any coolant?
Prestone is guaranteed to be compatible with any existing coolant in the cooling system, and offers long-lasting protection against wear, corrosion and extreme temperatures.
Can you mix prestone with other coolants?
Prestone is guaranteed to be compatible with any existing coolant in the cooling system, and offers long-lasting protection against wear, corrosion and extreme temperatures.
Is Prestone coolant ok for Subaru?
Trust Prestone – a leading global manufacturer of Original Equipment Antifreeze + Coolant. Can top off or replace any Blue antifreeze + coolant in all Honda; all Acura; Nissan 2009 and newer; Infiniti 2009 and newer & Subaru 2009 and newer vehicles, guaranteed.
Which coolant is best for Subaru?
I will do my best to try and explain which coolant is right for your Subaru at this time. If you own a 1990 to 2002 2.2l or a 1995 to 1999 DOHC 2.5l you can use just about any type of regular Green Antifreeze/coolant.
Is Prestone coolant really universal?
Formulated to work with All Vehicles. Universally works with all fluid colors; all OAT, POAT, HOAT & IAT. 5-year/150,000-mile Extended Life Formula. Meets or exceeds ASTM D3306 & D4985 for corrosion protection.
Can I put any coolant in my Subaru?
Every vehicle manufacturer, including Subaru has developed its own coolant or requires a particular coolant that is unique to explicit years and models. There are countless colors of coolants to help distinguish each including red, green, purple blue, yellow, and orange.
What happens if you use the wrong coolant?
Putting the Wrong Engine Coolant in Your Car
As mentioned above, the mix can solidify, block your engine, and cause overheating, which can, in turn, cause the following problems: Degraded cylinder heads. Head gasket breakage. Marred hoses.
