Update: It turns out for whatever reason, the power steering pump decided to stop working. After changing the pump, the problem seems to be fixed. Thanks to everyone that helped with this problem in this thread . During the process, we put together a video on changing the power steering reservoir which I'll link to the thread here: https://www.freel2.com/forum/topic39751.html

Just thinking about this and I always used the specifically recommended Pentosin CHF oil when I have done this job. Just doing some research on the web and on some of the forums people are saying that there is no real substitute, whether it's to do with it being mineral or synthetic based I don't know but I think I would start by flushing out the Halfords generic stuff and hope that you haven't screwed up some seals in the pump or rack.

This is the reservoir that I brought from eBay and it looks and feels like a genuine bottle. https://www.ebay.co.uk/itm/303324138763 Obviously i'd purchase another one from LR Parts if we end up buying a pump. At point 6 I feel like you have no option but to suck out the fluid from both reservoirs. Even if you run the fluid down to the minimum on the new reservoir, as soon as you remove the bung from the return port to then connect the return line, the fluid all comes spilling out. I fully expect the power steering pump to be at fault. But it confuses me how the power steering can go from working fine to not working at all with a simple reservoir change. Not only that, I'd like to know where I've gone wrong so I don't go wrong again with the new pump. DorsetFreelander: For all I know, the whining noise in the last thread could be linked to this problem. In that it was actually the power steering pump whining and gave up at the same time that we changed the belt, tensioner and idler. But that's a very loose theory. I get where you're coming from with the fluids. But surely if it's Central Hydraulic Fluid and conforms to CHF 202 then it's all much of a muchness. Whether it's Pentosin, Granville or Ravenol. I could understand if red power steering fluid was used. Plus it's the fluid Beavis Pits used in this video and it didn't cause him any issues: https://www.youtube.com/watch?v=cvae3VJSy_4 If we end up buying a pump I'll get the Ravenol that LR Parts sell just on the off chance. https://www.youtube.com/@scottandalana4x4 |

That Reservoir you bought is likely a Britpart make, I have never had a problem in using over three fluid changes. Just wondering; I assume the system was working before the change. I can't see in your posts if you tried re using the old Reservoir. I use Ravenol SSF with no problems but there again I am a sucker for blurb such as

Hi I Like Chips. We haven't tried putting the old one back on as of yet. I'm not sure if it will bug me enough to try the old filter and waste alot more fluid or just buy another one if it looks like we are heading down the new pump route.

I recently replaced the reservoir and bled the system into the old reservoir with the engine off. It was very easy as I removed the RH headlight to get better access to the hose clips. 1) sucked out old fluid from old reservoir and replaced it with the new reservoir, leaving the old reservoir on the return line supported to the side. 2) filled new reservoir with fluid making sure any air in the feed line has come out, and then turned wheels fully from side to side until new fluid filled old reservoir - old and new reservoirs will need to be emptied and topped up respectively during this bleeding. No air must be allowed to enter the feed line. 3) Attached return to new reservoir. 4) Bled again to be sure of no bubbles. 5) Done. Engine started. All good. Jules |

If the PAS pump and steering were working OK before then to my mind the most likely explanation is that you have somehow got some air into the system. Could the pump be air locked ? Also if you take the RH headlight out and move the washer filler you'll have much more access to the hose clips. Jules Last edited by jules on 22nd Jan 2024 1:29 pm. Edited 3 times in total |

If you'd bled the system fully, once reconnected I'd expect the level to remain static as there should be no air to come out and be replaced with fluid. Jules |

The JLR manual says bleed/flush the system using the engine (page 531). Trouble is , with the pump going it will flush 4L of fluid in 30secs (according to the manual) so its very easy to entrain air if you're doing it solo. Jules |

We were happily driving around in it with only a whine from what we now know to have been the tensioner or idler. Now that muggins here decided to change the reservoir, it's now very broken. I wouldn't of thought that we would've got any more air into the system than the next person doing the same job. Thanks alot for the headlight tip as that will come in very handy.
When we removed the new reservoir and refitted it on the 2nd stab, I was only confused by the level not dropping because there should've been an element of air left in the system as we didn't bleed it with the engine off on the 2nd attempt. We went by the service manual and went straight in with the engine on just in-case that made a difference.
I've seen Beavis Pits video and his reservoir emptied as soon as the car fired up. I didn't think I'd have quick enough reactions to turn the car on and off again before the reservoir ran dry if it tried that method. Thanks Rommel for vouching for the part. https://www.youtube.com/@scottandalana4x4 |

Right I'm not sure if this next video will make anything clearer or leave it more confusing. I went back out to the car and tried to bleed it again incase it's just air. The first oddness starts with this. With the engine off going lock-to-lock the reservoir bubbles away more than a bubble bath:

I just serviced mine today. I took a big syringe and sucked it full. Repeated until reservoir empty. Then clipped the two hoses off, then took off the bottle (original and now pretty yellow'ish), cleaned the bottle with a full can of brake cleaner spray, inspected it visually as good ad I could to be clean, and reinstalled it, and topped up with new CHF202 VAG (volkswagen group) synthetic green fluid, steered left right 6-7 times to dull lock, then sucked up old brown nasty stuff. Repeated until all was clear light green. Works well and no whining.
