Thread: ACE system bleed? how?

This is the way I'm gunna do it(someday)
remove the bottom hose from the res,, (catching the fluid)
block up the hole,
place hose in bucket,
fill res,
start car,
refill res as required,


make sense??

As per pedro says. I just extended the disconected outlet hose with some clear tube into a bucket, had someone start the engine and poured in the new stuff as the old came out!
There is also a filter in the valve block under the drivers door that needs changing at the time.
All went well.
I think with nanocom you can instruct the computer to extend and retract the rams - i't may be a more thourough flushing.

PS from what I could see, you don't use any old fluid either. It's either the genuine from land rover or fluid from penrite specifically for the job.

yep,, Transmaz Z
IF you can afford it,,
or the new Penrite stuff.

Hey Davros,,
is that filter washable or replacement only?

Considering the time between changes and the fact I'd already got one I installed a new one - but thinking about it, it's probably washable as from memory it's SS gauze (but an o ring needs changing i think). Anyone?

and this is why i want to do it properly, ive already sused out the old fluid..pretty sure it hasnt been changed in its 160thou life and the tranzmax just cost me $88 for 4L

see how i go on the weekend, i may be able to do a tut for future referance.

cheers phil

Sounds great Phil
I did my power steering flush last week but was a bit concerned about the ACE a tutorial would help me heaps.
Also where do you get the transmax? I used Penrite at $29 per litre for the steering

Hydraulic circuit bleeding: During ACE system maintenance or repair, hydraulic fluid may be lost from the system and air introduced. If air is present in the primary circuit (pump, attenuator and PCV) the system will self bleed shortly after starting the engine. The unwanted air will escape when it reaches the reservoir. When air is in the secondary circuit (actuators and associated pipe work) it is necessary to perform the System Bleed procedure using this function. Both actuators are designed to allow oil and air to flow freely through them when the piston is in the fully extended position. In this position, the air will be forced out and allowed to escape to the reservoir. Using the following procedure, it is possible to bleed the front and then the rear secondary circuits with the front secondary circuit being bled first, but it is critically important that both the front and rear actuators are bled independently.

1. The vehicle should be parked on a good solid 4 post ramp with the handbrake firmly on and in park or neutral.
2. Ensure that the fluid reservoir is kept topped up to the maximum and that the pump is primed (details of how to verify this and perform it can be found in the vehicle's workshop manual).
3. Having ensured that the engine is not running, raise the vehicle on the 4 post ramp to normal underside working height.
4. Disconnect both stabiliser links on the front axle only. Do not disconnect the stabiliser links on the front and rear axles at the same time. Free the nut that holds the silent block at the end of the roll bar.
5. Push the stabiliser link on the torsion bar end up and pull the stabiliser link on the actuator side down simultaneously to fully extend the actuator; make sure that no pipes or hoses become stretched or caught.
6. For added safety, lower the vehicle to ground height.
7. Start the engine and whilst it is running, perform the 'Hydraulic Circuit Bleeding' function.
   WARNING: The vehicle may suddenly jerk violently from side to side during this test and so it is vitally important to ensure sufficient clear space around the vehicle.
   The 'Hydraulic Circuit Bleeding' function will take around 10 minutes during which you should ensure that the fluid reservoir is kept topped up. When the 'Hydraulic Circuit Bleeding Function' has ended, turn off the engine.
8. Raise the vehicle on the 4 post ramp again and reconnect the front axle stabiliser links.
9. Disconnect both stabiliser links on the rear axle only. Do not disconnect the stabiliser links on the front and rear axles at the same time.
10. For added safety, lower the vehicle to ground height again.
11. Start the engine and whilst it is running perform the 'Hydraulic Circuit Bleeding' function.
    WARNING: The vehicle may suddenly jerk violently from side to side during this test and so it is vitally important to ensure sufficient clear space around the vehicle.
    The 'Hydraulic Circuit Bleeding' function will take around 10 minutes during which you should ensure that the fluid reservoir is kept topped up. When the 'Hydraulic Circuit Bleeding Function' has ended, turn off the engine.
12. Raise the vehicle on the 4 post ramp again and reconnect the rear axle stabiliser links.
13. Lower the vehicle to ground height and re check the fluid reservoir level.
14. Run all response time tests found in the 'OTHER' section and confirm that they all pass.

This might be Testbook function and possibly a Nanocom could be used. I have never bothered to find out.
