ARCO, to be brutally honest, does it really matter? In all the years of the taxis, I still have never changed a power steering pump in my life, and that's including taxis that have hit 1,000,000 km and personal vehicles that exceeded 500,000 km. I've had leaks I've fixed. I've had a power steering hose blow off on the old LTD, and the pump still ran another 200,000 km before the car got totalled, and that was the only "flush" that power steering system ever had.
Maverick: There's nothing wrong with a bit of a turkey baster type exchange. Trav is outlining the most effective procedure, but of course, he has the shop and the help, and the need to get things done quickly, properly, definitively, and efficiently. I use a series of reservoir exchanges because I have the time, and am usually working alone. However, if I went to Trav's shop to ask him to do that for me, he'd probably tell me to see a psychiatrist. And, the amount of fluid he'd have to go through if he had to repeat that on many customers's vehicles would be astronomical. I would characterise the reservoir flush as "better than nothing." It's also preferable because I'm messy enough in the shop to not be doing Trav's procedure unless I relegated myself to be the assistant.
