I took a peek at my PS fluid (CHF11S) and it's definitely black and nasty, so naturally i'm going to replace it with new. What i don't know is:

1. My car is an '04 with sport package, is there anything special I need to know about draining and refilling the system?

2. Does ARS and the sport suspension get it's fluid from the power steering reservoir?

3. Should I drain the system and refill or should I suck out the reservoir, drive and refill a bunch of times? If I can drain it and refill is there any special process to it? Where should I drain from?

if you want to flush it completly, you have to disconnect the line down by the power steering pump....lower drivers side of the engine.
its a little tough to get to.

i just disconnected the powers steering fluid line that goes from the resorvoir down to the cooler. there is a quick-connect there behind the radiator. it gets a lot of it out. i did that a couple times.

Does that drain the ARS as well?

active roll sysytem?? yeah, my method drains all the resorvoir and some of the fluid in the lines.

i did the suction method before too. you need a long hose to stick down past some of the plastic obstruction inside the resorvoir.

How do I bleed the system once I drain and refill?

incase i wasnt clear, the active roll system is shared with the power steering system, same fluid.

to bleed, after filling with fluid, just start the car, wait a few moments, then turn the wheel from side to side a couple times.

Awesome, thanks for the help, one more question. Do you have any idea on capacity of the system? I bought 2 liters of CHF11S and I have a feeling I'm going to need more.

if you just suck out the resorvoir only, you will need almost 1 liter. if you disconnect the power steering line behind the radiator(bottom), you will need somewhere between 1 and 2 liters. cant remember...
