⚠️ STOP! Don't Mix These Coolants
Which coolant should you use? Find out in under 60 seconds!
This short and clear video explains the general differences often seen between red, blue, and green coolants—and helps you understand which type may fit your engine.
Here’s what you’ll learn:
Lifespan: Many red OAT coolants last longer (up to 5–7 years), while some blue and green types are shorter-life (around 2–3 years), depending on the formula.
Hybrid compatibility: Modern OAT-type coolants are commonly used in many hybrid engines — but always check the specific formula required for your vehicle.
Technology: Red coolants are often OAT-based. Blue and green can be IAT or HOAT depending on the manufacturer.
Engine types: OAT coolants are typically recommended for modern aluminum engines. Traditional green/blue IAT coolants are more common in older cast-iron engines.
Don’t mix coolants: Mixing different types can cause buildup, corrosion, or cooling system damage.
Always check your manual: Color is not a universal standard — manufacturers dye coolants differently. Always follow the specs in your owner’s manual.
Fast facts + clear visuals = everything you need to know, quickly.
Protect your engine and choose the right coolant for long-term performance.
