Additional Notes

  • The Honda Accord IV CB/CC cooling system carries an initial fill capacity of 6.6-7.2 liters, a figure associated with a full drain and refill of the entire cooling circuit, such as after a major overhaul or when the system has been completely emptied.
  • The service fill capacity of 3-3.6 liters is notably lower than the initial fill, reflecting the volume exchanged during a routine coolant change where residual fluid remains in the engine block and heater core passages.
  • Under normal use conditions, the coolant change interval for the 2.2 DX and LX trims is set at 24,000 miles or 24 months, whichever comes first.
  • A first change only condition extends the initial coolant change interval for the 2.2 DX and LX to 48,000 miles or 48 months, after which the standard 24,000-mile or 24-month cycle applies.
  • The 2.2 EX trim covering 1989-1991 shares the same initial fill range of 6.6-7.2 liters and service fill range of 3-3.6 liters as the DX and LX configurations, with identical normal and first change only intervals.
  • The 2.2 EX variant spanning 1991-1993 carries the same capacity values and interval structure as the earlier 1989-1991 EX, meaning no revision to coolant specifications occurred across the EX trim within the Accord IV generation.
  • Across all listed trims, the 2:1 ratio between initial fill and service fill capacity indicates that roughly half the total system volume is accessible during a standard service drain, a characteristic common to engines with block passages that do not fully drain without pressurized flushing.
