Coolant, anti-freeze mixture and freezing point


Check the anti-freeze. The coolant should be able to withstand at least -30°C (-22°F). It will then also provide maximum corrosion protection. In certain climates, it is necessary for the coolant to withstand even lower temperatures. If necessary, top up with a 1:1 mixture of Saab Original Antifreeze and water.

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 to operating temperature (=thermostat opening), check the level of the coolant and top up as necessary.
