amboy19 Posted May 30, 2004 Posted May 30, 2004 Hi everybody! New member but old reader of these forums. Great passionate and knowledgeable members! Hope to contribute my 2 cents worth in the future. I used to have an auto body shop for 10 years. Let the questions flow! Presently, I'm at my wits end on my power steering on my 97 LS400 (Coach Edition). Bought with minor front damage. I installed a used power steering pump. I see the fluid is foamy and system groans specially in low speed steering. Followed manufacturer suggested procedure in bleeding (lock to lock). But still I have the groaning and foaming. Can't seem to find any kinks in the lines, though. Before buying/installing a remanufactured pump, I'd like put a last ditch effort. I would like to locate the solenoid screen other members are talking about to cleand the filter if I have one. I cannot seem to locate mine. Anybody with pictures? Thanks a million. If you want direct contact: jrl119@yahoo.com.
mbpgawest Posted May 30, 2004 Posted May 30, 2004 Hi amboy19, I believe the screen is found by removing the sensor that is located on the drivers side of the powersteering rack. It will have 2 wires coming off of it. From what I have read you need a chisel to take it off. I was planning on checking mine out when I do my struts in a couple weeks. Good Luck! Let me know if you find it. Mark
VMF Posted May 31, 2004 Posted May 31, 2004 i dont think that the clogged scren will cause air in the pps. leave the reservoir open for one night and see if you will still get the bubbles. it helped in my case.

VMF Posted May 31, 2004 Posted May 31, 2004 i did the oem procedure too and i still had some bubbles left and some1 here suggested leaving the cap off for the night. so do it just in case:)its not gonna make it worse.
UCF3 Posted May 31, 2004 Posted May 31, 2004 -_- , not sure what leaving the cap open overnight will really do. Have you tried turning the steering wheel side to side-while running the engine (not familiar with OEM Procedure)?
VMF Posted May 31, 2004 Posted May 31, 2004 OEM procedure includes bleeding the pps and turning wheels when they are on the ground and when the car is jacked up. but in some cases its not enuff to get all the air. i did pps flushon my car and ps pump replacement on my friends GS and the open cap is the ultimate solution to get all the bubbles out.
99lsguy Posted May 31, 2004 Posted May 31, 2004 Yes: You are suppose to turn wheels lock to lock and hold for about 2 secs (cycle 2-3 times). This is with engine off and engine on idle. I kept my tires just off ground for both ways. Easier to turn & doesn't scuff the tires! When my car was on idle, I left the P/S cap on LOOSELY while turning lock to lock to let the air escape.
amboy19 Posted June 12, 2004 Author Posted June 12, 2004 thanks to all of you replying to my thread! just an fyi. my problem seems to have been resolved so far. we tried 99lsguy's approach and it seemed to work. this forum is heaven sent! keep in touch. if there's any painting problems i can be of help with, please don't hesitate to email me jrl119@yahoo.com. have a great summer!
99lsguy Posted June 12, 2004 Posted June 12, 2004 glad your back in business!!! Here's a link to a current post that gives info on the solenoid screen...... http://us.lexusownersclub.com/forums/index...pic=10145&st=0& I'm going to give a go at this soon - 500 miles to next oil change and I'll get after it.
