Additional Notes
- The Honda Insight ZE1 cooling system capacity differs by transmission type across all listed configurations: 4 liters when paired with a CVT and 3.9 liters when paired with a manual transmission or transaxle.
- A 0.1-liter difference between the CVT and manual transmission variants is a small but consistent distinction, reflecting the minor variation in coolant routing or reservoir volume between the two drivetrain configurations.
- For both the USA and CAN markets covering 1999-2001, the normal-use coolant change interval is set at 30,000 miles or 24 months, whichever comes first.
- The first-change-only interval for 1999-2001 USA and CAN models extends to 45,000 miles or 36 months, meaning the initial factory-fill coolant is rated to last longer than subsequent refills under the same normal-use conditions.
- From 2001-2006, the normal-use change interval doubles to 60,000 miles or 60 months for both the USA and CAN markets, a significant extension compared to the 1999-2001 specification.
- The first-change-only interval for 2001-2006 models reaches 120,000 miles or 120 months, which is 10 years or roughly twice the extended normal-use interval for the same period.
- The USA and CAN market specifications are identical across all four use-condition rows, with no variation in capacity or interval values between the two markets for any model year range listed.
- The shift from a 24-month to a 60-month normal-use interval between the 1999-2001 and 2001-2006 configurations indicates a change in coolant service life expectations, likely tied to a different coolant formulation adopted mid-generation.
