Additional Notes
- The Kia Sephia 1.8 (CAN) cooling system holds 6 liters of coolant, a figure that reflects the total system capacity rather than a partial top-off volume, meaning a full drain and refill procedure accounts for the entire 6-liter fill.
- The 6-liter capacity applies across the 1998-2002 model years of the Canadian 1.8 configuration, indicating no variation in cooling system volume was introduced during that production span.
- The service interval for the Canadian 1.8 is set at 30,000 miles or 30 months, whichever comes first, with both thresholds tied specifically to normal use conditions rather than a more demanding service classification.
- A 30-month time interval running alongside the 30,000-mile mileage threshold means lower-mileage vehicles still reach a coolant change point based on elapsed time alone, as coolant degrades chemically over time regardless of distance driven.
