Coolant Replacement
WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
All entrapped air must be purged from the powertrain cooling system before final coolant level can be determined. Proper coolant level is critical to avoid engine damage.
IMPORTANT: Vehicle must be level when filling cooling system.
- Slowly add a mixture of 50/50 DEX-COOL antifreeze and clean water to coolant surge tank until the level reaches the top of the "Cold fill Range" (surge tank seam). Cooling system volumes, including heater core:
- 6-Cyl - 8.0L (8.45 qt.)
- 4-Cyl - 7.0L (7.4 qt.)
- Start engine and check for leaks.
- Run engine and cycle the vehicle from idle to 3000 rpms in 30 second intervals until the engine cooling fan comes on (engine cooling fan turns on at approximately 216°F [102°C]).
- Return the engine to idle, idle for 30 seconds then turn engine off.
- Add coolant to the surge tank until the level reaches surge tank vent port.
IMPORTANT: Level in the surge tank will return into the cold fill range once the vehicle cools.
- Install coolant surge tank cap.
