Is your coolant the right color? 🚗❄️
It’s not just for show—the color of your antifreeze tells you exactly what’s happening inside your engine. Using the wrong one can lead to corrosion, clogs, and costly repairs!
Here is your quick guide to staying cool:
* 🟢 GREEN (IAT): Best for vintage and older vehicles (contains phosphates/silicates).
* 🔴 RED / PINK (OAT): The "Long Life" choice using organic acids for extended protection.
* 🔵 BLUE (HOAT): Designed for modern engines using hybrid organic technology.
* 🟡 YELLOW: Hybrid Technology—the go-to for multi-brand use (BMW, VW, Renault, etc.).
* 🟠 ORANGE: Extended Protection specifically for high-temperature environments.
Pro Tip: Never mix colors! Stick to the technology recommended in your owner's manual to keep your cooling system healthy.
