Bad smell from air conditioning system.
|
Saab 9000 and Saab 900 with A/C or ACC.
During certain weather conditions the climate control system can give off a bad smell when the car is started. The following method of surface treatment for the evaporator prevents this smell arising.
300 23 59 Equipment kit
|
•
|
Adapter
The above material can be reused.
|
|
•
|
1 bottle 120 ml Saab Odour Remover A/C
Saab Odour Remover A/C can be ordered separately as part number:
300 23 67 1 bottle 120 ml Saab Odour Remover A/C
|
To apply the Saab Odour Remover correctly, follow the instructions carefully. If they are not followed carefully there is a great risk that the surface treatment will rinse off and have no effect.
The treatment takes approx. two hours but the real working time is only about 30 minutes. The rest of the time is spent drying the evaporator and surface treatment agent.
If the surface treatment agent does not get enough time to dry it will be rinsed off within two weeks.
