Does the Car Coolant Type and Brand Matter?
To ensure compatibility, focus on factors like chemical composition, color, and the recommendations in your vehicle’s manual. Prioritize a coolant that offers corrosion protection and has the right boiling and freezing points for your climate. By selecting the appropriate coolant type, you’ll maintain engine health and longevity, making it a valuable investment in your vehicle’s future.
How to Choose a Car Coolant - Buying Guide
With so many coolants available, picking the right one can be overwhelming. To help you make an informed decision, we've highlighted key features and considerations for choosing the best coolant for your vehicle. For a more detailed overview, check out our buying guide below:
Check Your Vehicle's Manual for the Right Coolant Type
- Green coolants: Represent Inorganic Additive Technology (IAT) and are best suited for older vehicles like Toyota Corollas and Honda Civics from the 1990s. These coolants require more frequent changes to maintain performance and prevent corrosion.
- Red Coolants: Typically Organic Acid Technology (OAT), these are designed for modern vehicles with aluminum engines, such as the Toyota Vios and Honda City. They offer longer-lasting protection and generally require less frequent changes compared to green coolants.
- Orange coolants: Often Hybrid Organic Acid Technology (HOAT), these are suitable for a variety of newer models, including SUVs like the Mitsubishi Montero Sport. HOAT coolants provide robust corrosion protection and are compatible with both aluminum and copper components.
Opt for a Coolant With High Boiling and Low Freezing Points
In a tropical country like the Philippines, where temperatures can soar, selecting a coolant with a high boiling point is essential. Look for coolants with a boiling point of at least 108°C (226°F) when mixed 50/50 with water. This will help prevent overheating during hot, humid weather, especially in heavy traffic.
While freezing isn't a common concern in most parts of the Philippines, it's still important to choose a coolant with a low freezing point for those who travel to cooler regions or higher altitudes like Baguio or Tagaytay. Aim for a coolant that provides protection down to at least -37°C (-34°F) in a 50/50 mixture. This ensures your engine remains protected during occasional cold snaps or if you plan trips to cooler destinations.
Look for Coolants With Extended Life Formulations for Less Frequent Changes
Extended-life coolants are a great option for drivers who want to reduce the frequency of coolant changes and lower maintenance costs. These formulations typically last between 150,000 to 200,000 kilometers or up to 5 years. Look for coolants labeled as "long-life" or "extended-life" and check their specific lifespan claims. These products often contain advanced organic acid technology (OAT) or hybrid organic acid technology (HOAT) additives that provide superior protection against corrosion and degradation.
While extended-life coolants may have a higher upfront cost, they offer significant savings in the long run by reducing the frequency of coolant changes. This is particularly beneficial for drivers who face heavy traffic and challenging road conditions, which can put extra stress on vehicle cooling systems. However, it's crucial to follow the manufacturer's recommendations and regularly check coolant levels and quality, especially given the Philippines' hot and humid climate.
Ensure the Coolant Is Compatible With Your Engine’s Metals
For older vehicles with copper or brass radiators, choose coolants that offer protection for these metals. These coolants typically contain phosphates or silicates that form a protective layer on metal surfaces. Always check your vehicle's manual or consult a trusted mechanic to determine the best coolant type for your specific engine configuration.
Choose Coolants With Corrosion Protection Properties
Silicates provide quick protection but may wear out over time, while organic acids offer long-lasting corrosion resistance. Some coolants combine both for comprehensive protection. Selecting a coolant with strong corrosion inhibitors can help extend your engine’s lifespan and maintain performance, even in the Philippines' challenging conditions.
Consider Environmentally Friendly Coolant Options
As environmental awareness rises in the Philippines, many drivers seek eco-friendly vehicle maintenance options. Look for coolants labeled "biodegradable" or "environmentally friendly," which often use propylene glycol, a less toxic alternative to ethylene glycol. Although slightly pricier, these products align with the country's environmental concerns.
Eco-friendly coolants are especially beneficial in areas near water sources or sensitive ecosystems. Always follow local regulations for disposal, and use recycling facilities. Some auto shops in Manila, Cebu, and Davao offer coolant recycling services, helping drivers make environmentally responsible choices.
