Hi,

You have the right fluid. I did a little checking and found there is a technical service bulletin related to bleeding the PS system.

If you look below, I attached the bulletin for you to review. It indicates using a vacuum pump to remove all air from the system.

Take a look and let me know your thoughts.

Take care,

Joe
