thanks alot for the heads up glad to hear u fixed it.

 

Not to sound like a jackass or anything, but how did you flush the power steering system?

Thanks.

 

I pulled off the top hose going into the reservoir and put it into a 1 gallon milk jug. I then capped the top nipple on the reservoir and had my wife run the car at an idle while I poured fluid in the fill spout. You must pour fast so as to keep the pump from sucking air and cavitating. I ran about 6 quarts of tranny fluid through it while she was turning the wheels from side to side. Also, the one gallon jug I had filled up pretty fast.

6 quarts? Wow...i just flushed mine due to my fmic install and i only ran 1 quart through it and the other quart to fill it up...

edit- i did not know we could only put tranny fluid with dexon III in our power steering..but good thing when i was flushing it a few friends were there to help me out with the fmic install and informed me...

 

I used extra just to flush it out. It did not take that much, I just wasted a shitload! Peice of mind!

 

Just curious, but what is the standard power steering fluid that Toyota recommends?

After I had mine filled with some power steering fluid bought at Target, I think there is some noise when turning the wheel. What do you guys think? Should I do the flush?

 

automatic transmission fluid DEXRON -II or -III

 

Yes, In the owners manual it says to use Dexeron II fluid.

But in my personal experience I've found it very difficult to use DexeronII, it foams up sooo easily and takes forever to quiet down.

As far as it stopping leaks that does have a little to do with the ATF. If your fluid is dirty the dirt sticks to the seals (o-rings Etc..)
and the pressure moves the seals around a bit letting the dirt between the surfaces thus creating a leak. Flushing the fluid removes the debris. ATF helps more than P/S fluid because ATF is high in detergent which is also why it foams up so easily. I reccomend to just flush the P/S system out with P/S fluid, less hasle. BTW from the factory the system has P/S fluid in it not ATF.

What are the temperature characteristics of Dextron II or III vs. P/S fluid? Do I need to be more/less concerned about boilover with ATF rather than P/S fluid?

What are you using in your car, Ishii?
Thanks.

Have you ever heard the expression...

The Electricians lights don't work, the Gardners yard is messy, the plumbers pipes leak and the Mechanics car don't run...

I havn't had my current supra that long, and my P/S pump was already bad when I first got. I'm too lazy to repair it, it doesn't bother me at all since I only drive my car maybe once a month.
But I will use Power steering fluid. The fluid in mine has never been exchanged so it still has the factory P/S fluid in it.

P/S fluid has anti foaming agents in it. Dexeron II/III is a little different in viscosity.

Thanks. That's what I was looking for.

I think you need to get that baby out on the track with us. We're going out on the 22nd (and others from PacNW on 23rd) ... and there's a school day that morning (22nd) as well.

I have some pads you can borrow...

 

The difference is all on the breakdown actually. The temperature breakdown is what separates the fluids. The viscosity is just because tranny fluid can get hotter so ATF is meant to be thicker but the actual difference for the power steering part of it is the temperature breakdown.

 

so to be safe, u should just go to a toyota dealer and get the power steering fluid then?

so will toyota give you transmission fluid dex. II/III for it?

i never heard of this til now, thank god i've read this

 

as I see it p/s fluid is still the way to go.

 

Maybee quick... but I put over 1300 miles on my car going to TX2K4. Maybee my old fluid was just that... old. Never-the-less, the tranny fluid seems to work well while my leaks, whining, and hard turning went away. I guess time will tell. I would however think that tranny fluid would resist burning a little better than power steering fluid. Sounds like you have researched this though.

Brandon

 

Haven't done a huge amount of research, Brandon. ...but Ishii's opinion is quite valuable to me. He's a Toyota master tech and knows Supras like the back of his hand... better than most people here, actually. If he'd use PS fluid in his car then that's what I'm using.

Please don't take offense to that, ok? We can pursue different approaches -- they'll probably both end up working out ok.

The PS tank cap says to use Dexeron II ATF.

 

The PS tank cap says to use Dexeron II ATF.

Well shit. Good eye, Tim!

Sure enough "Use Dextron type ATF" is emblazoned on the cap.

I take it back. Wierd.

 

damn, this is all confusing now

so its either p/s fluid, atf II, or tranny fluid?

 

I'm going to run what the resevoir cap indicates I guess. That seems like the safest bet.

 

The PS tank cap says to use Dexeron II ATF.

No shit! Well there it is!

 

The main point is just to exchange the fluid.
If IGGYWOOWOO had used ps fluid to flush his system I'm sure that the results would have been the same.
I like that ps fluid doesn't foam up so much making it faster to use which is why I reccomend it.
I had already mentioned that toyota says to use ATF dexeron II ,
if you went to a toyota dealer they would sell you maybe castrol ps fluid or something because toyota doesn't have a Ps fluid for dealership retail sale, only ATF.
Once again the owners manual and the cap say to use dexeronII, but when the car is brand new it comes with PS fluid in it.
The power steering is just like the engine, you shouldn't wait until it starts to make noise and then change the oil.

Same can be said for any fluid in the vehicle. They all need to be changed from time to time

iggywoowoo

thanks bro

 

Hey guys i had the whining problem in my 95 tt it is not the fluid but a very fine filter at the bottom of the tank which get clog over the years causing a lack of fluid to the pump. I used either fluids and they work ok.

 

can this filter be changed for a new one?
