Filling Procedure
WARNING: This page is about a different car, the 2009 Pontiac Torrent and 2009 Chevrolet Equinox. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When the radiator is drained, a minimum of 5 liters (5.28 qts) of coolant is typically drained from the cooling system. During the fill procedure, a minimum of 5 liters (5.28 qts) of coolant should be added to the cooling system before the vehicle is returned to the customer.
- Close the drain valve on the left radiator end tank.
- Install the engine block drain plug, if removed.
- Open the air bleed screw on the water pump tower.
- Slowly add a mixture of 50/50 DEX-COOL antifreeze and clean water to the surge tank. Refer to Approximate Fluid Capacities
for cooling system capacity.
- As the system begins to fill, watch for coolant at the water pump tower.
- As coolant begins to seep from the air bleed, close the air bleed screw.
- Once the bleed screw is closed, continue to add coolant until a minimum of 5 liters (5.28 qts) is added to the cooling system. Start the engine and run at idle to add the remaining coolant.
- Install the surge tank cap.
- Run the engine and cycle the vehicle from idle to 3,000 RPM in 30 second intervals until the engine cooling fans come ON.
- Return the engine to idle, idle for 30 seconds then turn the engine OFF.
- Allow the vehicle to cool.
- Add coolant to the surge tank until the level is approximately 25 mm (1 in) above the top of the Cold Fill Range at the surge tank seam.
- Install the surge tank cap.
CAUTION:
All entrapped air must be purged from the powertrain cooling system before the final coolant level can be determined. Proper coolant level is critical to avoid engine damage.
NOTE:
The vehicle must be level when filling the cooling system.
