| | Coolant/cooling system Check the anti-freeze mixture. The coolant must be able to withstand -30° to -35°C (-22 to -31°F). Top up as needed with 50%% SAAB Original Coolant and 50%% water. | Important | This mixture also provides effective corrosion protection. | Avoid mixing different types of coolant. Fill the system when the engine is cold but not above the MAX level mark. Warm up the engine until the thermostat opens and check the level of the coolant. Check the condition of the hoses. | Important | Screw the filler cap down hard or the system will not be pressurized, resulting in a lower boiling point and loss of coolant. |
