1994 LS 400 Power steering riddle
first day to the forum. here is my issue. My power steering has a mistery. I do not have a power steering leak and it seems to work just fine,until the weather gets cold. In Houston, it was finally cold the week of Thanksgiving. as I drove to work it was about 45 degrees, my power steering was out, or partially out. When I accelerate over 1600 rpms, it loosens up and works, but when I am below that it is out. now that same day even when the engine is hot, when the tempeture outside gets over 50 degrees it works fine no matter what rpms I am at. To reconfirm this to me, this past week we had a cold rush. In the morning it was 70 degrees, p/s running great. at 3pm the tempeture had dropped below 50 degrees and my p/s went haywire. back to out at idle and then when accelerated over 1500 rpms it works. what do you think?

I have flushed out the reservoir twice and run the vehicle both times. It is at its set fluid level and I aam using what is recommended in the manual. thanks for the response.

Hmmm I think you should do some quick searches. I dont remember the part name but there is something that is on the steering rack itself that is involved with the speed sensor side of things. I cant quite remember it right now. Just do a search on power steering and you will see what I mean.

there are 2 screens in the ps system that you should be concerned with:
1) screen at the bottom of the reservoir on the ps pump itself
2) screen in the solenoid/pressure valve on the steering rack that pito is referring to
do a forum search, there are plenty of threads with photos regarding the solenoid.

Power Steering Leaking
Hey Guys & Gals,
I own a 1995 LS400 and today I noticed fluid under my Power steering Pump and also on the steering rack (the same side with the pump). I want to think that the leak is from the pump but the pump works fine. I have not experienced any problem with it thus far.
Please tell me what could be the possible cause of this and how could it be resolved.
In addition, I am hearing a constant noise from my engine that I used to hear only for few minutes when the engine is cold. It sound like a "pinking" noise. Any suggestion as to the cause of this noise would be helpful.
Thank you very much in advance.
