Does Honda use blue antifreeze?
Yes — for most modern Honda and Acura vehicles, the recommended Genuine Antifreeze/Coolant is blue (Type 2). Older Hondas used green coolant. Always verify with your owner's manual or a dealer for your exact model and market.
Understanding Honda's coolant colors
Color coding helps identify the general coolant type, but the precise specification comes from official documentation. Honda's current long-life coolant is blue, sold as Type 2, and is designed for extended service in most contemporary engines. Some older models or regional variants may have used different formulations; mixing coolant colors or types is not advised.
Checklist to confirm the correct coolant for your Honda:
- Check the owner's manual for the approved coolant type and color (Blue, Type 2 for most newer Honda/Acura models).
- Look for a label on the expansion reservoir, radiator cap, or under-hood sticker that says "Genuine Honda Antifreeze/Coolant Type 2 — Blue."
- If the label is missing or you are unsure, contact a Honda dealer or certified mechanic with your vehicle's VIN to verify the correct specification.
- Important: Do not mix blue Type 2 with green Type 1 or other colors; if you suspect a mix, a professional flush and fill may be required to restore proper protection.
Correctly identifying the blue coolant helps ensure proper corrosion protection and cooling performance throughout the vehicle's life.
Historical colors and compatibility in Honda models
Honda's color story spans generations and regions:
- Type 1 Green: Used in many older Honda models; green coolants are typically not compatible with Type 2 without a system flush.
- Type 2 Blue: The current standard for most modern Honda and Acura models; blue coolant is associated with longer-life maintenance schedules outlined in the owner's manual.
- Regional variations: Some markets may label variants differently, but the recommended color and type should be verified per vehicle documentation.
In practice, if you're maintaining a modern Honda, blue Type 2 coolant is the safe default, with green Type 1 limited to older or specialized vehicles.
Summary
Bottom line: Yes, Honda commonly uses blue antifreeze today for most models, corresponding to Honda Genuine Antifreeze/Coolant Type 2. Older Hondas used green coolant (Type 1). Always verify with your owner's manual or a Honda dealer and never mix coolant types or colors.
