Car care and technical information Changing the coolant (Usually carried out as part of the Saab original service by an authorized Saab dealer) 1 If the engine is hot, open the expansion-tank filler cap carefully to release the pressure, but do not remove it completely. Place a suitable receptacle under the radiator and undo the draincock. 2 Remove the filler cap on the expansion tank. 3 The system takes about two minutes to drain. Close the draincock. 4 Mix the antifreeze and water to the required strength in a suitable container. Use only Saab-approved coolant. 5 Add the coolant slowly to the expansion tank. This will take about two minutes, as the air needs time to escape. 6 Screw on the filler cap and fully tighten the drain cook. Run the engine to normal temperature. Top up the coolant, as necessary, until the level is just below the MAX mark on the tank. 7 Check the coolant again after a few days and top up as necessary. 175 Radiator draincock Brake and clutch-fluid reservoir Brake and clutch fluid WARNING Brake fluid deteriorates as it becomes old. Because it is hygroscopic, it absorbs water from the air and, in time, could allow vapor to form in the brake system, thus reducing its performance. It is therefore important that brake fluid be changed regularly, as specified in the service program. Checking the fluid level The combined brake and clutch-fluid reservoir is transparent to facilitate checking of the fluid level. IB1188 IB498
