196 Car care and technical information

The cooling system is charged at the factory

with coolant containing a 45 % concentra-

tion of a combined antifreeze and corrosion

inhibitor. A weaker mixture will result in

reduced anticorrosion protection. For

protection against freezing in very cold

weather, a stronger concentration will be

needed.

A 60 % concentration of antifreeze will pro-

vide protection at temperatures down to

–58°F (–50°C).

The coolant does not normally have to be

changed during the service life of the car.

The type of coolant used has a reddish color

and should not be mixed with other types of

coolant. Saab Original coolant should be

used all year round. Only use coolant

approved by Saab.

Note:

If incorrect coolant is used or added, the

life-time 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.

Brake and clutch fluid

Checking the fluid level

The combined brake and clutch-fluid reser-

voir is transparent to facilitate checking of

the fluid level.

The level should be between the MAX and

MIN marks. Top up, as necessary, with

DOT 4 fluid. Do not use DOT 5 brake fluid.

NOTE

Always mix the antifreeze with the

appropriate volume of water before

adding it to the cooling system.

If pure 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.

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 reg-

ularly, as specified in the service pro-

gram.
