Which car models use purple coolant?

Models like BYD use purple coolant. Coolant generally comes in different colors such as purple, green, and blue, depending on the specific car model. How to choose coolant: The basic indicators of coolant are freezing point and boiling point. On the market, coolant freezing points include specifications like -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region. Coolant replacement cycle: For vehicles that run for long periods, such as taxis, high-quality coolant should generally be replaced once a year. For vehicles with shorter running times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolants can have a validity period of up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the coolant, it should be replaced promptly, and the system should be cleaned.

Having driven for over a decade, I've noticed that coolant colors are quite specific. Purple usually indicates the OAT (Organic Acid Technology) type, which offers excellent corrosion resistance and protects the engine system. Many high-end European models use this, such as the Mercedes-Benz C-Class and S-Class, BMW 3 Series and 5 Series, and Audi A4 and A6. But it's not just these brands—some Japanese models like Lexus also use the purple variant. The key point is that color isn't the only standard; you must check the type recommended in the owner's manual. Otherwise, mixing different types of coolant may damage the water pump or radiator. The replacement interval is typically every 5 years or 100,000 kilometers. Choosing the right one brings many benefits, extending the vehicle's lifespan.

As a new driver, I've been pondering about the color of antifreeze recently. Purple antifreeze is quite common, especially in luxury models like the Mercedes-Benz GLC or BMW X5 SUVs, which use purple OAT antifreeze. The color looks cool, but it actually represents the antifreeze's formula, designed to protect the engine cooling system in high-temperature environments. Don't just decide which type to change based on color alone; getting it wrong could cause problems. I recommend checking the car's maintenance manual directly or asking a technician at the 4S store for safer advice. Remember not to mix antifreeze randomly, as different brands are incompatible.

Having worked in the repair shop for so many years, I've handled all kinds of coolant issues. Purple coolant is mostly OAT-type, commonly used in German brands like BMW and Audi, such as the 3 Series or Q7. The color is an auxiliary identifier added by dye, but the core is to match the vehicle's specifications. The car model doesn't specify the color; just refer to the original manual. Safety first, otherwise the wrong coolant can cause cooling system leaks or engine overheating. When changing the coolant, drain the old fluid completely before adding the new one, ensuring the mixing ratio is correct.
