A quick video to show how to flush and change the fluid in you SAAB convertible cabriolet.
Not a big different after, a little faster but the liquid was the same since I own the car ( 8 years... ) and it was so dirty and dusty inside...
No special tools needed, just a 13mm key or socket and something pump or seringe to vaccum.

From the brand Pentosin, that's a very high quality alternative product that i use now as it's starting difficult to find original GM fluid without paying the price of a gold bar...
