Additional Notes
- The Kia Sedona GQ 3.5 (CAN) carries a cooling system capacity of 8.2 liters across both the 2002-2003 and 2004-2006 model year ranges, indicating a consistent total system fill volume regardless of the production period.
- An 8.2-liter cooling system capacity is a relatively large fill volume for a minivan of this era, reflecting the demands of a 3.5-liter V6 engine requiring adequate thermal management across the full system, including the engine block, cylinder heads, heater core, and radiator.
- The 2002-2003 Sedona 3.5 (CAN) specifies a coolant check interval of every 7,500 miles or 6 months under normal use conditions, while the 2004-2006 range tightens the check interval to every 5,000 miles or 4 months, also under normal use conditions.
- Despite the difference in check intervals between the two production periods, the coolant change interval remains identical at 30,000 miles or 24 months for both the 2002-2003 and 2004-2006 Sedona 3.5 (CAN) under normal use conditions.
- A 30,000-mile or 24-month change interval is characteristic of conventional or early long-life coolant formulations, as opposed to extended-life coolants that typically carry intervals of 100,000 miles or more.
- The more frequent check interval introduced for the 2004-2006 model years, at 5,000 miles or 4 months versus the earlier 7,500 miles or 6 months, reflects a shorter monitoring cycle between full drain-and-fill services while the change interval itself stays unchanged.
