You are wasting your time with a turkey baster. Disconnect the return pipe to the header reservoir and extend the pipe to a container on the floor, plug the tank. Empty the tank and fill with clean fluid. Run the engine for 2 seconds or use an assistant to keep the header full of clean fluid keep doing this until the fluid is running clean into the catch container also ensure you run the rack to full lock in both directions. Ensure you do not run the pump with no fluid. Reconnect and top up to the appropriate level. Dirty steering fluid is not a good sign. Regards Peter
