This system is all complicated and confusing to me, so please forgive my ignorance.

How should this system be "flushed"? I've searched and seen some people do a flush their self, and other say you need a machine to suck it out....and Hell, I think there were 2 or 3 other ways I read besides those.

I haven't changed out the PS fluid....ever, since I bought the car new in 2002 and it's been 7 years and 40,000 miles on it. It looks very very dark, maybe brownish in color. Hard to tell.

I did boil the brake fluid pretty bad at the track event this weekend and thats the first time i've ever had that happen to me. Does this in any way relate to the PS fluid used for the hydroboost?

The steering feels fine, or has felt like it always has....maybe it's a little "thicker" when steering quickly, maybe it's in my head.

Any advice or links to some answers would be appreciated, thanks.

Power Steering System Flushing

WARNING: Do not mix oil types. Any mixture or any unapproved oil can lead to seal deterioration and leaks. A leak can ultimately cause loss of fluid, which can result in a loss of power steering assist. Failure to follow these instructions may result in personal injury.

Remove the power steering fluid reservoir cap.
Using a suitable suction device, remove the power steering fluid from the reservoir.
Disconnect the power steering fluid return hose from the reservoir.
Remove the clamp.
Plug the reservoir inlet port.
Attach an extension hose to the power steering return hose.
NOTE: Do not reuse the power steering fluid that has been flushed from the power steering system.

Place the open end of the extension hose into a suitable container.
CAUTION: Do not overfill the reservoir.

Fill the power steering fluid reservoir with clean fluid.
CAUTION: Do not allow the power steering pump to run completely dry of power steering fluid.

Start the engine while simultaneously turning the steering wheel to lock and then immediately turn the ignition to OFF.
CAUTION: Avoid turning the steering wheel without the engine running as this may cause air to be pulled into the steering gear.

CAUTION: Do not overfill the reservoir.

Fill the power steering fluid reservoir with the approved power steering fluid.
Repeat Steps 8 and 9, turning the steering wheel in the opposite direction each time, until the fluid exiting the power steering fluid return hose is clean and clear of foreign material.
Remove the extension hose from the power steering return hose.
Remove the plug from the power steering fluid reservoir inlet port.
Install the power steering return hose to the reservoir.
Install the clamp.
NOTE: It is necessary to properly fill the power steering system to remove any trapped air and completely fill the power steering system components.

If after properly filling the power steering system there is power steering noise accompanied by evidence of aerated fluid and there are no fluid leaks, it may be necesaary to purge the power steering sytem. For additional information, refer to Power Steering System Purging in this section.


Fill the power steering system.



Personally...Id just use a 1/2 quart suction gun...or brake bleeder kit...and suck it down low.....fill...then actuate the brakes and steering from lock to lock...and keep repeating the process...

Sounds like a time consuming pain. I'll print this page off and take it with me in the garage.

Thanks!

I pulled my return line loose at the cooler at the lower left side of the radiator ,plugged the line and put a hose on the hard cooler line which I stuck in my oil drain pan then did the run,turn and fill routine.

Read your owners manual to confirm but mine calls for MerconV.

I'll see if I can find it. Who knows, Ford may've switched "recommendations" 3 or 5 times since 2002.

Yeah, you gotta read all the TSBs and whatnot that have come out since your car was made. Ferinstance, I think they're recommending 5w20 oil nowadays instead of 10w30.

I think it says 5w-20 on my oil cap, but I never could find it here in my town so I always put 5w-30 in there. My last few oil changes i've seen it the 5-20 pop up from time to time.

Not to mention the gay TR3650 trans that has more oil options(opinions) than a political debate.
