Other Power steering fluid

gstuart · May 17, 2020

Hiya

hope everyone is keeping safe and well

may i ask please , as part of a service I was thinking of replacing my power steering fluid ,just wondering if it’s any easy job of just emptying it by removing the return pipe, ( that’s if I can get to it) turning the wheel from side to side To empty it , then filling it back up

or is it a nightmare to do and best to be left alone

many thks

Do you have a bleed nipple? Like the early boxes
If you do I would connect pipe to it
& empty about 1/2 the reservoir,refill the do the same again.(engine running)
Probally easier to do than removing removing pipes

I have the D2 and every so often I draw an amount out of the resevoir and top up with fresh fluid, so over a period of time it gets changed. No need to bleed it then.

Many thks

to be honest I’m not 100% if there’s a bleed nipple, will have to check but removing the fluid over a period of time also sounds like a good idea

many thks as always

Just suck out whats there, add fresh, run it for a few seconds switch off, suck it out again, and top it up job done, you wont get all of it, but it will be fine, after all very few people ever change their pas oil unless they have a leak.
The trucks never see fresh pas oil, again unless something fails (quite rare) so some of it will be years and many 100s of thousand kms old.

Iirc meant to be cold temp stuff, not sure how critical that bit is, but its not mega expensive for a litre.

I'm one of the very few then

my disco has the fluid it left the factory and the same with my RR which was serviced by a main dealer for the 10years I owned it, it's not listed in a service schedule for both models.

hiya

many thks and just looked on advance , ref Land Rover Cold Climate PAS Fluid 14315 LRN2261,
https://www.advancedfactors.co.uk/a...spec-can-replace-stc50519-chf11-1230924-p.asp

Indeed is only £10 for a litre

also didn't realise it had a power steering fluid cooler

thks again

ps, hope this also helps , just seen that from the bottom of the reservoir to the min is approx 190mm , plus there is a mesh filter at the bottom

Definitely check that mesh filter. It can get clogged.

Here are pics how I flush my PS system...
Jack up front of Disco and add jack stands.
Suck out old fluid and refill with new fluid...

Attach hose to nipple and loosen with 11mm spanner...

Allow hose to drain into oil pan while turning steering wheel lock to lock until new fluid and no bubbles are seen...

Then tighten 11mm nipple and top up reservoir.

Dont think D3 has a nipple as it has a rack rather than a box.

Filter is a subjective thing, some say change/clean annually, others say do not open the system for anything apart from major repair for fear of introducing dirt into the system.

I agree with the explanations from this article: https://barsleaks.com/uncategorized/when-is-it-time-to-change-power-steering-fluid/ , even if it's not mentioned in the LR maintainance schedule i changed it in my D2 as it looked dirty and the pump became less noisy and the steering softer

Here's my method: I emptied the reservoir with a pump, undone the return pipe, attached a piece of hose to it and directed it into a 1.5l bottle in te engine bay , clogged the return port with a bung, filled a 1.5l bottle with PAS fluid, started the engine and kept filling the tank with engine running untill the bottle was empty, stopped the engine unclogged the return port and reattached the pipe, job done, no bleeding was needed and the fluid is all new this way.

I do the same (Penrite PAS fluid for steering and ACE reservoirs) - very quick to do each time you do a service. If you have a turkey baster (tapered tube with large bulb for basting turkeys) then that works best, or else use a large plastic syringe and piece of tubing to suck out old fluid.
