Changing the Power Steering Fluid in an Aston Martin DB9

After 17 years it was time to flush and change the Power Steering Fluid in my 2005 Aston Martin DB9 Coupe. When it was cold outside and I would start my car occasionally the steering would feel heavy or even judder for the first few moments. Aston Martin had issued Field Service Bulleting FSB 11-0300 describing the proper procedure to completely flush out the original Texaco Cold Climate fluid and replace it with new Pentosin CHF-11S. In this video I cover that procedure.
