Default Integra Power Steering Fluid Flush

I have a 1997 Integra and have been changing fluids while I have the time. Aleady have done everything except the power steering.
I did a search and didn't really find any helpful info. I know I am supposed to disconnect one of the hoses and drain while pouring the new stuff in then turn the wheel back and forth while on jacks.
My question is which exact hose am I supposed to disconnect and which end should I be using. Pics would be great but descriptions would also be helpful (e.g. hose connected to the pump from the reservoir, disconnect from the reservoir end...hose connected to the aluminum tube. disconnect from the aluminum cooling? tube end...etc)
I hate asking but I've had problems buying the helm manual, www.helminc.com has had it unavailable for months. Thanks in advanced.

Lift the front of the car so the steering rack doesn't have to do any hard work. Get ready for a little bit of a mess.

Actually, I removed the reservoir entirely. (I can never do this without making a mess.) I cleaned out the reservoir & set it aside to dry.

One hose from the PS reservoir goes directly to the pump. On the OTHER one, add some hose to a drain bucket or something. Idle the engine, turn steering full-lock back & forth a couple times, shut off engine. Don't run any longer than you have to.

Put it all back, fill it up, idle, turn steering back & forth. Now the fluid will be all foamy in the reservoir. Go have a beer while the foam collapses. Top up the reservoir & run it again. Repeat until it's not foamy any more. That's maybe 3 times?

Next time I do this, I'm probably going to drain from the cooler tube that runs across in front of the radiator. On the '98 Accord there's a real convenient place to disconnect that.

I am guessing that you are referring to the hose that doesn't connect from the reservoir to the pump but to the other hose to the reservoir. It looks like a bitch to take out without scuffing my arms.

Btw, the guys at Acura told me about three 12oz.(356ml.) bottles of Honda PSF would be enough for the flush. They also called 12oz. a pint, I am not really down with the non-metric volumes but I think this is wrong (16oz = 1 pint I think).

Actually, I disconnected BOTH hoses, because I removed the reservoir to clean it. The return hose is the one that doesn't go directly to the pump, and that return hose is the one that spits out fluid when you run the steering back & forth.

My specs say the fluid capacity is 1.54 quarts, which is 1.45 liters. But when I refilled, it didn't take that much. Maybe 2 or 3 bottles (about 1 liter). So obviously a bunch of fluid still stays in the rack or somewhere.

Yes, 16oz. is one pint. But they're right about using 3 bottles for each drain/fill.
