Hi all,

wondering if anyone has anything similar occur....

Basically on startup, the power steering is very noisy but then goes away once the car has warmed up.

The power steering pump has had a full reco around 18 months ago. Before then, the noise was constant.

Any help would be greatly appreciated.

cheers

Is the fluid aerated/bubbly in the reservoir?

100% its p/s? Dropped the belt and rechecked ?

Would suck if say it was an idler or tensioner pulley and just sounded like it was coming from p/s pump area then let go

Not sure, it's just really strange that on a cold morning startup the car is fine, no noises. If right then I do a dry steer, the loud noise starts. Once the car has warmed up a bit, it's all perfect and quiet!!! What the!!

this was the symptom of mine as the power steering pump was getting on - noisy when cold and dry steering, then would go away.

it will gradually get worse if it is indeed the PS pump.

bottom line is you can leave them for a while without any trouble.

Mine started having a noticeable effect on the slow speed steering when the car was still warming up until I did anything (replaced the PS pump).

good luck!

You can try replacing the fluid to help with cold temp steering. As fluid gets old and sludgey and is thicker than normal when cold. This means it isn't lubing the system as well. Draining the fluid and replacing it with fresh fluid can help.

I have to get around to doing it to my Commodore at some point (when I could be bothered, along with finding the cause of the slight misfire it has). had a leaky pump for ages and had put some stuff in it that was supposed to slow/stop leaks. Basically it was a thick fluid. I finally got a new pump but didn't completely flush the system (just topped it up really), so on cold mornings the steering has a bit of a notch just off straight. Once it warms up it's fine. I did some googling and that's when I found out about flushing the system (which made sense, since the fluid is thinner when warm, and on really cold mornings it was much worse, to a point where on a sub zero morning I had no power steering the first time I tried to turn the wheel).

      R34 GTT idle problem

      By Dose Pipe Sutututu · Posted

      Oh yeah forgot to also mention need to also unplug the IACV as well. Thanks for the reminder @MBS206 Unplugging the TPS takes it out of closed loop so you're able to screw down the IACV without the ECU trying to add/subtract timing to maintain the idle (not sure PowerFC can even do this, but Nistune and the OEM definitely does)

      For sale is my 1999 Nissan Skyline R34 GT-T, tuned to 234 kW / 313 hp. I've had the car for a few years as my daily driver. The car is original (as far as Skylines go), with only a few minor upgrades to enhance performance and driving experience, as typical for such a car of its age. Overall, it is in great condition with no body rust, thanks to its earlier import date. It features a top-notch security system (not literally, but it's great!) with remote start and still functional 4-wheel steering via HICAS. It comes with several performance and handling upgrades, including:     Hypergear 450HP Turbocharger running 17 PSI boost, installed mid-2021 by Jaustech     550cc injectors     Nistune ECU     Front-Mount Return-Flow Intercooler     X-Force Stainless Steel Exhaust     Upgraded engine mounts     Bottom end bearings replaced     BC Coilovers     Lenso DR1 rims     Bridgestone Potenza Adrenalin RE003 TL 245/40R18 97W tires, fitted early 2023 The interior is mostly stock, with a few additions:     Viper Satellite Tracking System with remote start     Bluetooth Double-Din Touchscreen Head Unit     Steering wheel cover Cons:     A few paint imperfections here and there     Driver’s seat shows more wear than the others. It's not torn at all, but I've added a seat cover to protect its condition. I also have a CarVX Vehicle History report available for serious buyers, so you don’t need to purchase it yourself. Price: $26,000 ONO.

      Troubleshooting - motor wont turn over

      By TurboTapin · Posted

      I've had two suzukis in the past have an extremely hard time turning over and not starting after sitting for a few weeks. Ended up the alternator would seize up causing the starter to force. Same issue both times.  Maybe they're sourcing their alternators from the same place...
