The 2017 Honda Civic uses Honda Long Life Coolant Type 2, blue premixed in a 50/50 solution with distilled water. This specification is designed specifically for Honda engines, and refilling should use the same Type 2 coolant to maintain optimal cooling and warranty compliance.
Understanding the coolant specification
Honda’s Long Life Coolant Type 2 is the standard for many late-model Civics, including the 2017 model year. It is formulated to protect aluminum cooling-system components and provide robust corrosion resistance. For everyday maintenance, most shops and parts stores stock this coolant premixed in a 50/50 ratio, which eliminates the need for additional water unless you’re purchasing a concentrate. Always confirm the exact specification on the bottle and avoid mixing with non-Honda coolants.
What to buy and how to use it
Before listing options, note the essentials about purchasing coolant for this model:
- Use Honda Long Life Coolant Type 2 (blue) for the 2017 Civic; it is the factory-recommended specification.
- Most sellers offer this coolant premixed in a 50/50 solution, so you generally won’t need to dilute it yourself.
- Avoid mixing with non-Honda coolants or other coolant families, as incompatible chemistries can cause corrosion, foaming, or cooling-system failure.
- Look for clear labeling that states “Honda Long Life Coolant Type 2” or an equivalent Honda-approved designation.
- If you must use concentrate, dilute exactly per the instructions and only use the approved Type 2 formulation for Honda engines; premixed is the simplest and safest option.
Following these guidelines helps ensure proper cooling performance and protects the vehicle’s cooling system over time.
Maintenance guidance and common questions
Routine coolant maintenance involves inspecting for leaks, discoloration, and proper levels, and replacing the coolant on the schedule recommended in the owner's manual. For many Honda Civics, the coolant is designed to last about 10 years or 120,000 miles, whichever comes first, though you should verify the exact interval in your manual or with a dealer. If you’re unsure about the coolant currently in the system—especially if it shows unusual color or contamination—have a technician flush and refill with the correct Type 2 coolant.
Summary
In short, the 2017 Honda Civic uses Honda Long Life Coolant Type 2 (blue), sold premixed in a 50/50 solution. Use only this specification for refills and avoid mixing with other brands or types. Always consult the owner's manual or a Honda dealer for the precise replacement interval and service recommendations.
