^Thanks for the tip. I'm planning to do this along with changing the O-Ring on the P/S pump.
On step #4, OP suggests not to empty the reservoir, but not completely empty it. So, at what point should I stop turning the power steering pump?
For example, should I stop when the old fluid is barely visible inside the reservoir? I imagine even with empty reservoir, there still would be fluid inside the hose, so, it still technically won't cause any problem.
