210 Car care and technical information Engine compartment Clean the engine compartment using an engine detergent and rinse with hot water. Cover the headlights and do not aim the spray nozzle on the Radiator. Throttle cable. Throttle housing. Other engine controls. The alternator. Ignition system and other electrical components. Additional care should be taken if using a high-pressure washer. Hold the nozzle at right angles to the area to be cleaned, which is particularly important when spraying labels. Do not use gasoline as a cleaning agent or solvent when carrying out repairs or maintenance. Saab recommends the use of environmentally safe degreasing agents. Touching up the paint Damaged paintwork should be treated as soon as it is discovered: the longer it is left, the greater the risk of corrosion. The anti-perforation warranty does not cover corrosion resulting from untreated defects. Paintwork damage sustained in a collision is usually extensive and can only be properly restored by professionals. However, you can repair small scratches and stone-chip damage yourself. The necessary tools and materials, such as primer, touch-up paint and brushes, are available from your Saab dealer. In the case of minor flaws in the paintwork, where the metal has not been exposed and an undamaged layer of paint remains, touch-up paint can usually be applied directly, after any dirt has been scraped away using a pointed knife.

If possible, the damaged area should be taken back to the bare metal. The metal should then be primed with two thin coats of primer applied by brush. After the primer has dried, apply several thin layers of topcoat enamel until the surface of the repaired area is flush with the surrounding paintwork. IB1334
