Learn the vital differences of the antifreeze coolant colours meaning
At e-CAR Menlyn, we believe in empowering our customers with knowledge. This comprehensive guide will decode the mystery behind antifreeze coolant colours in South Africa, ensuring you make the right choices for your beloved vehicle.
What colour coolants do we use in South Africa?
The different colours of antifreeze coolant are primarily intended to help differentiate between various formulations and the types of additives they contain. While there isn’t a strict, universally enforced global standard, certain colour conventions are widely adopted. Understanding these can save you from costly mistakes.
Green Coolant:
Historically, green was the most common colour for antifreeze coolant. This traditional formula is often referred to as Inorganic Additive Technology (IAT). IAT coolants typically use inorganic inhibitors like silicates and phosphates to prevent corrosion. While effective, these inhibitors deplete relatively quickly, generally requiring coolant flushes every two years or around 40,000 to 50,000 kilometers. In South Africa, you might still encounter green coolant, particularly in older vehicles.
Orange or Yellow Coolant:
Orange or yellow coolants usually signify Organic Acid Technology (OAT). These formulations utilize organic acids like carboxylates to provide long-lasting corrosion protection. OAT coolants generally have a much longer service life compared to IAT coolants, often recommended for five years or 240,000 kilometers. Many modern vehicles, especially those from European and American manufacturers, come filled with OAT coolants. This advanced technology offers superior protection and extended drain intervals.
Pink or Red Coolant:
Pink or red coolants often represent Hybrid Organic Acid Technology (HOAT) or Phosphate Hybrid Organic Acid Technology (P-HOAT). These coolants combine the benefits of both inorganic and organic inhibitors, offering excellent long-term protection. HOAT coolants are frequently found in Chrysler, Ford, and some European vehicles. P-HOAT coolants, which include phosphates, are common in many Asian vehicles, including Toyota and Honda. These extended-life coolants typically have service intervals similar to OAT coolants.
Blue Coolant:
Blue coolant is frequently used by Asian vehicle manufacturers like Nissan and Hyundai. While it might sometimes be an OAT or HOAT formulation, it’s crucial not to assume it’s directly interchangeable with other blue coolants. Always check your vehicle’s owner’s manual for the specific coolant type recommended by the manufacturer.
Purple or Violet Coolant:
You might encounter purple or violet coolants in some newer vehicles, often representing advanced extended-life formulations. These are typically OAT or HOAT coolants with specific additive packages designed for particular engine requirements. Again, consulting your owner’s manual is paramount.
Why Colour Alone Isn't Enough
While coolant colour provides a helpful initial indication of the type of coolant, it’s not a definitive identifier. Variations exist between manufacturers, and some aftermarket coolants might use colours that don’t strictly adhere to the common conventions. Therefore, always prioritize checking your vehicle’s owner’s manual and the coolant product label to ensure compatibility. Look for specific standards and manufacturer approvals mentioned on the coolant container.
The Golden Rule: Never Mix Coolant Types!
This is a critical point. Mixing different types of coolant can be extremely detrimental to your vehicle’s cooling system. The incompatible additives can react with each other, forming sludge and deposits that can clog your radiator, water pump, and coolant passages. This can lead to overheating, engine damage, and costly repairs. Always use the coolant type specified in your vehicle’s owner’s manual. If you’re unsure, our expert technicians at e-CAR Menlyn are always ready to assist you.
