Car care 209 Air filter WARNING To ensure reliable operation, only use an air filter recommended by Saab Automobile AB. Coolant WARNING • Proceed with caution if the radiator is boiling when you open the hood. Never remove the expansion-tank filler cap when the radiator is boiling. • The cooling system is pressurized - hot coolant and vapor can escape when the filler cap is released. These can cause injury to your eyes and burns. Loosen the cap carefully, and let the engine cool before removing the cap. • Exercise care when adding coolant. Coolant on hot surfaces constitutes a fire risk. There is an overpressure in the cooling system. Coolant temperatures can sometimes exceed 212° F (100° C). If the coolant level drops too low, the following message appears on the SID: Coolant level low. Refill. The properties of the coolant are retained for the entire service life of the car. Therefore, it is not necessary to change the coolant. The coolant contains 45 % antifreeze and anti-corrosion fluid. This ratio gives the best cooling effect. Lower concentrations should be avoided, in view of the corrosion risk. Coolants of a different brand could damage the engine or cooling system. We therefore recommend strict use of coolants that have been approved by Saab. Transmission fluid Manual transmission Check and top up the oil in accordance with the service program. Automatic transmission Check and top up the oil in accordance with the service program. NOTICE If the cooling system needs topping up, mix the antifreeze with the appropriate quantity of drinking water or distilled water before adding it to the system. If undiluted antifreeze is added, the engine could still freeze and be damaged. This is because the antifreeze will not mix properly with the coolant before the thermostat has opened to allow full circulation. Note: If incorrect coolant is used or added, the lifetime properties will be affected. Even if the coolant is flushed from the system and replaced with life-time coolant, life-time properties are no longer retained and the coolant must then be drained and replaced at regular intervals.
