Kia Telluride, ON (USA / CAN)

Additional Notes

• The Kia Telluride 3.8 GDI AWD carries a cooling system capacity of 12.2 liters across all listed configurations from 2019 onward, a volume consistent with a full-system service fill rather than a partial top-off or reservoir-only service.
• Under normal use conditions, the cooling system interval is set at 30,000 miles or 24 months, whichever comes first, meaning the time-based trigger of two years can prompt a change well before the mileage threshold is reached in lower-mileage applications.
• A separate first-change-only interval of 120,000 miles or 120 months applies across all listed configurations, reflecting the extended service life of a factory-fill coolant formulation before the standard recurring interval takes over.
• The pairing of a first-change-only interval with a subsequent normal-use interval indicates a two-phase coolant service schedule, where the initial factory fill is treated differently from all following service fills.
• The 120-month first-change interval translates to a 10-year window, which is a characteristic of long-life coolant types such as OAT (Organic Acid Technology) formulations commonly used as factory fills in modern vehicles.
• Following the first change, the 24-month time interval under normal use conditions becomes the more practically limiting factor for many owners, as two years elapses faster than 30,000 miles for average annual mileage patterns.
• The 12.2-liter capacity figure remains unchanged across the 2019-2022 model year range in the specifications, indicating no cooling system volume revision was introduced for the 3.8 GDI AWD configuration during that period.
