The 2019 Honda Fit uses Honda Long-Life Coolant Type 2 (blue), typically sold premixed in a 50/50 ratio with distilled water, or an equivalent coolant that meets Honda’s Type 2 specification. Avoid Dex-Cool or other non–Type 2 formulations.
Honda specifies this coolant to protect the cooling system and engine components from corrosion and overheating. For the Fit, the official guidance centers on using a Type 2 coolant that is compatible with Honda materials and cooling-system design. If you’re replacing coolant, follow the manual or consult a dealer to ensure you’re using the correct product and mixing ratio for your market.
Recommended coolant type
Key facts about the correct coolant are summarized here before the list of specifics.
- Honda Long-Life Coolant Type 2 (blue), also known as Honda Type 2 coolant, is the approved specification for the 2019 Fit.
- Most commonly available as premixed 50/50 coolant with distilled water, ready to pour.
- If purchasing concentrate, mix it with distilled water to a 50/50 ratio exactly as directed on the product label.
- Use genuine Honda coolant or an equivalent that explicitly meets Honda Type 2 specifications; avoid non–Type 2 formulations unless your manual or dealer confirms compatibility.
Using the correct Type 2 coolant (blue) protects cooling-system alloys and seals, and helps maintain proper engine operating temperatures.
How to check and refill coolant safely
Before starting any work, remember to let the engine cool completely to prevent burns and pressure-related injuries.
- Park on a level surface and allow the engine to cool, then locate the coolant reservoir and radiator cap.
- Check the reservoir level against the “FULL COLD” or similar indicator when the engine is cold.
- If the level is low, add the correct Honda Type 2 coolant up to the indicated mark. Do not add plain water alone if you’re not maintaining the 50/50 mix.
- If you’re performing a complete drain and fill or a system flush, follow the service manual instructions to drain, flush, and refill with Type 2 coolant at 50/50 with distilled water.
- After filling, reinstall the cap securely and start the engine briefly with the radiator cap off to help bleed air from the system. Monitor for leaks and stop if you notice any dripping or excessive pressure.
- Let the engine reach operating temperature, then recheck the level after it cools and top off if necessary to the proper cold-fill line.
Properly bleeding the cooling system and maintaining the correct level helps prevent overheating and keeps the engine protected. If you notice persistent low levels, overheating, or leaks, consult a technician or Honda dealer.
Summary
For a 2019 Honda Fit, the recommended coolant is Honda Long-Life Coolant Type 2 (blue), typically sold premixed in a 50/50 blend with distilled water.
