buster Posted November 5, 2010 Share Posted November 5, 2010 i may well be answering my own question here but need to double check.. my power steering seems rather heavy and with the help of a friend the problem seems to be that the fluid is not moving in the resevoir. so with that in mine we believe that i could be either the pump or hopefully the power steering pressure switch,which we believe opens the flow to the rack ? the pump still makes all the right noises but the steering is just heavy. your help on this would be welcome.

Chilli Red Posted November 5, 2010 Share Posted November 5, 2010 Tony says its a fair possibility it's the pump. Mark had a similar issue and it was the pump. Quote Link to comment Share on other sites More sharing options...

R35LEE Posted November 24, 2010 Share Posted November 24, 2010 Does sound like the pump mate. 2 in stock if you need one Quote Link to comment Share on other sites More sharing options...
Chris`I Posted November 24, 2010 Share Posted November 24, 2010 I take it you've tried the full lock one way to full lock the other to make sure theres no stuck air? I'm sure I heard someone say that you can get air in there from time to time and doing it lock to lock can get it out Quote Link to comment Share on other sites More sharing options...

Lincolnbaggie Posted November 27, 2010 Share Posted November 27, 2010 Correct bleeding technique is listed below: 1. Stop the engine, and then turn the steering wheel fully to right and left several times. NOTE: While air bleeding the Hydraulic System, frequently check the reservoir tank, add additional fluid up to the MAX level, if necessary. 2. Run engine at idle speed, hold steering wheel at each “lock†position for about three seconds. 3. Repeat the 2nd procedure several times at about three seconds intervals. CAUTION: Do not hold steering wheel in the locked position more than 10 seconds. (It is the possibility that oil pump may be damaged.) 4. Check generation of air bubbles and cloud in the fluid. 5. If the air bubbles and the cloud don't fade, stop the engine, leave air bleeding behind until the air bubbles and the cloud fade. Perform the 2nd and the 3rd procedures again. 6. Stop the engine, check fluid level. Quote Link to comment Share on other sites More sharing options...
Chris`I Posted November 27, 2010 Share Posted November 27, 2010 Oooh, get you Mr Proper Seeing as my bodge way of doing it worked, its worth doing the proper bleed as per Neils post. Remember to keep an eye on the fluid as when you get the air out, its replaced by fluid, and if there is no fluid it cant get all the air out.

car350z Posted August 25, 2011 Share Posted August 25, 2011 Sorry to dig up this old post but I'm having the same problem with my power steering. It's always been a bit heavy but wasn't a problem. However recently it got much worse. I can hardly turn the steering wheel at low revs. I tried bleeding the system but no luck. I did notice a few things though: When I rev it up a bit (2500-3000) and then turn the wheel, there is a very loud whining noise. Not just when steering is all the way to the left or right, but also when turning left or right from straight. At those revs, the steering is expectedly light. When I go all the way left or right and rev the engine, there is a noise and I can see very small drops of liquid from (what I assume is) a valve towards the pump. The belts and pulleys look fine and surprisingly, the fluid level in the container does not drop noticeably. Another thing, when I start the car in the morning and everything is cold, the power steerings works fine, it only stops after a while. Also, the previous owner had replaced the fluid container with some aftermarket part. This container has a lid with a little air hole in the middle. Is that ok or is the PAS system a closed (as in pressurized) one? The fluid does get warm in the container so I'm thinking that there is at least some circulation in the system. Any ideas what I should do with it? Do I need a new pump or a new valve? Where can I get those? If necessary I can provide some photos, though it'll be pretty impossible to shoot the little drops of fluid as they are really tiny.

stubzie83 Posted August 25, 2011 Share Posted August 25, 2011 Has the car been used regularly/daily? When I bought mine last year it seemed that it hadn't been used that much for a while by the previous owner. The steering was really heavy and the gear box was very tight. After some daily use the power steering got lighter and the gearbox felt a lot better. I think the regular use helps to get all the fluids moving and probably gets any stuck air out of the power steering system. Quote Link to comment Share on other sites More sharing options...
car350z Posted August 25, 2011 Share Posted August 25, 2011 The car is in daily use. When I bought it the previous owner just got it out of dry storage where it had been for 7 months, but that was in November 2010. And it was fine then, it just recently got much worse.

HaydnH Posted August 30, 2011 Share Posted August 30, 2011 I doubt this is the issue and I wouldn't try it on the Z for fear of frying something, I just thought I'd share. On the Mk2 MR2 there was a known issue where the power steering would go heavy due to a dodgy connection, turning the ignition on (electrics only) and off repeatedly in quick succession would fix the issue... weird!

northernmonkey Posted September 14, 2011 Share Posted September 14, 2011 Glad you got it sorted. What's the cost of a pump? Quote Link to comment Share on other sites More sharing options...
