Honda Integra (EU)

Additional Notes

• The Honda Integra (EU) 1.5, 1.5i, and 1.6i-16V variants from 1986-1989 all share an identical cooling system capacity of 5.6 liters, indicating no meaningful difference in cooling system volume across those three engine configurations of that generation.
• The 5.6-liter figure for the 1986-1989 models represents a single capacity value with no distinction between initial fill and service fill, meaning the full system volume applies uniformly regardless of whether the coolant is being replaced during routine maintenance or after a full drain.
• The Integra Type R DC2 from 1997-2002 carries a notably larger cooling system, with an initial fill capacity of 6.5 liters compared to the 5.6 liters seen in the 1986-1989 models.
• On the Integra Type R DC2, the service fill capacity of 4.0 liters is substantially lower than the 6.5-liter initial fill, reflecting that a standard coolant drain during routine maintenance does not evacuate the entire system, leaving residual fluid in the engine block and heater circuit.
• The Type R DC2 under normal use conditions follows a change interval of 40,000 km or 48 months, which is the same interval applied to all three 1986-1989 variants.
• Under the initial service use condition, the Type R DC2 carries an extended first-change interval of 80,000 km or 48 months, doubling the distance threshold while keeping the same time limit of 48 months relative to the normal use interval.
• The time-based limit of 48 months remains constant across both the normal and initial service intervals for the Type R DC2, meaning the calendar limit acts as an absolute ceiling regardless of mileage accumulation.
