power stearing problems

[XtSupra]

hello guys, I have a 95 TT MT supra and I have been having problems with the power stearing. it seems to me that's overheating or something. it would be fine for half an hour or so of driving then all of the sudden it will sound as there is no fluid in it, and when I open up the fluid revisor, the fluid looks like it's foaming or something (it becomes a very light pink color), and when I leave the car off for a couple of hours or so, it will be normal again. it's not leaking or anything, it just does that when I drive it for sometime. I am not sure wether this car comes with a power stearing cooler or not, at least I remember with my Eclipse, the power stearing had somesort of metal hose that mounts in front of the radiator, and too me that sure looked like a power stearing fluid cooler, do supras have the same thing, cause I am not sure if the last owner of the car decided to take it off for whatever reason.

so sum things up

- do Supras come with power stearing cooler?
- and if not, do you guys think I am getting a leak somewhere that causes the fluid to foam up?
- what else could you guys think of that might cause the fluid to foam up?

any help would be appreciated.

thanks

The filter in the reservoir is choked up due to dirt in the system. Dirt in the system usually = knackered rack seals, and cleaning it all out usually only effects a temporary cure. Oversize wheels and tyres seem to casue rapid rack wear as well as bottom ball joint wear, are you on big wheels and tyres?

I am running 18" wheels. I could only think of 2 things, first, the last owner of the car switched one of the powersteering pipes with smaller ones which causes the fluid to chock somewhere and dries out the rack, or the fluid is just overheating. here is what I found out, while the car is standing still, and the revisor cap is off, and turnning the steering wheel right and left with the rpm at around 2k or so, the rack will make that anoying noise (dried out rack noise) and the fluid will spell out of the revisor, this happen in 1-2 minutes or so. so since raising the rpm while turning the wheels causes that, then I am leaning toward the idea of pressure build up somwhere which causes the rack to get no fluid and instead, the fluid gets spelled out of the revisor.


thanks a lot for the reply Chris.

The filters blocked.

The filters blocked.



Chris, where are the filters located at? any tips on cleaning them, or does that mean I have to replace the power Rack?


thanks

I think it's at the bottom of the PAS fluid reservoir, and all you have to do is take the reservoir out of the car and flush it out :)

Ian C is right, a strainer in the bottom of the resevoir, but it shouldn't be mucky in the fiorst place!
