Buyer’s Guide
Now, let us talk about the most important aspects you need to take into consideration before choosing the right one for your Subaru.
Inorganic Acid Technology (IAT)
IAT is the traditional green coolant used in many older vehicles. It’s been around for decades and primarily works by using silicates and phosphates. While it’s suitable for many cars, it might not always be the best choice for modern Subaru models due to its shorter lifespan.
Organic Acid Technology (OAT) & Hybrid Organic Acid Technology (HOAT)
These are typically the coolants found in newer vehicle models, including many Subarus. OAT and HOAT coolants have longer lifespans than IAT, with fewer corrosive properties, making them ideal for modern engines that require longer maintenance intervals.
Checking Compatibility
Always read the label when purchasing coolant for your Subaru. Manufacturers will often list which vehicles or types of engines the coolant is designed for. Some might be specific to certain Subaru models, while others are more generic.
Consulting the Owner’s Manual
Your Subaru’s owner manual is a treasure trove of information. It’ll specify the type of coolant recommended by Subaru itself. When in doubt, always refer to the manual or consult with a Subaru technician.
Frequency of Changing Coolant
Generally, it’s advised to change the coolant every 30,000 miles or every 3-5 years, whichever comes first. However, with advanced formulations, some coolants can last even longer without compromising engine health.
Specific to Subaru
Subaru vehicles, with their unique engine configurations, might have specific recommendations for coolant changes. Always keep a check on the coolant’s color and consistency. If it’s murky or has debris floating, it’s time for a change.
Eco-friendly Options
The automotive industry is moving towards more sustainable practices. Several coolant brands now offer eco-friendly antifreeze options that are biodegradable and less toxic to the environment, which is an excellent choice for environmentally-conscious Subaru owners.
Disposal of Old Coolant
Coolant shouldn’t be disposed of carelessly, as it can harm the environment. Always ensure you’re disposing of used coolant at a local hazardous waste facility or automotive shop that offers disposal services.
Pricing and Brands
While many brands claim to be the best for Subaru, always choose reputable brands known for quality. Often, these brands have undergone rigorous testing to ensure their product’s efficacy and compatibility with Subaru engines.
Cost vs. Quality
While it might be tempting to go for the cheapest option available, remember that coolant plays a vital role in your Subaru’s performance. Investing a little more might ensure a product that offers better protection, longevity, and overall benefits.
DIY vs. Professional Assistance
Changing coolant is a task many Subaru owners feel confident doing. With the right tools and a bit of research, it can be a straightforward process. Ensure you’re in a well-ventilated area and have the necessary equipment like gloves and safety goggles.
If you’re unsure or don’t have the time, seeking assistance from a professional or a Subaru technician is always a wise choice. They’ll have the expertise and tools to ensure the coolant is changed correctly, giving you peace of mind.
