Kia Forte, BDm (USA / CAN)

Additional Notes

• The Kia Forte BDm 1.6 T-GDI carries a cooling system capacity of 6.9 liters, which is notably larger than the 2.0 MPI's 5.3–5.4 liter range, reflecting the greater thermal management demands of a turbocharged engine compared to a naturally aspirated one.
• The 2.0 MPI's capacity is listed as a range of 5.3–5.4 liters rather than a single fixed value, which typically indicates a minor variation between production batches or assembly tolerances within the same engine family across the 2019-2024 span.
• Across both engine configurations, the first-change-only interval is set at 120,000 miles or 120 months. A first-change-only designation means the factory-fill coolant is formulated to last significantly longer before the initial drain, after which a different service schedule applies.
• For the 1.6 T-GDI covering model years 2019-2022 and 2022-2024, the normal-use coolant change interval holds at 30,000 miles or 24 months in both periods, indicating no revision to the standard service schedule across those production spans.
• The 2.0 MPI shows a change in the normal-use interval between production periods. For 2019-2022, the interval is 30,000 miles or 24 months, while for 2022-2024 the mileage threshold drops to 24,000 miles, though the 24-month time limit remains the same.
• Despite the interval adjustment on the 2.0 MPI for 2022-2024 normal use, the first-change-only interval of 120,000 miles or 120 months remains unchanged from the earlier 2019-2022 specification, meaning only the recurring service cadence was revised.
• The 24-month time-based limit appearing across normal-use rows for both engines means that calendar time can trigger a coolant change before the mileage threshold is reached, which is common in lower-mileage driving patterns.
