QUICK AHC BLEED QUERIE

[Urtwob]

Hi guys, a quick question, when doing an AHC oil refresh,

The FSM says to place the cruiser in the N position pre bleeding each consecutive point,



My first question;

would I not get more of the old oil out of the system if I put the cruiser in the AHC HI position and step it down through N to Lo before closing the bleed point, and repeating this process through each respective bleed point. My theory being would that not mean a more thorough flush of the old oil out of the system.



My Second Question;

what is the best practice,

Bleed Height accumulator first,

Bleed Right hand Front Damping force globe

Bleed Left hand Front Damping force globe

Bleed Right hand rear Damping force globe

Bleed Left hand rear Damping force Globe



I think I read somewhere that there was no need to bleed both front globes and then both rear globes as they are always linked to each other. Ie bleeding Front Right Hand Damping force Globe will also Bleed Front Left hand Damping force Globe at the same time.



However my theory here being that to repeat the bleed process Hi through to Lo on both Front globes and then the both Rear globes would help flush out even more of the old fluid.



Any advice on both points would be most welcome

I start in H. Simple because, less remains in reservoir to suck out. It also, is easier see under vehicle.

Thank you. Much appreciated.

I pulled all of the fluid out of the reservoir in low, filled it to the top, then drained the accumulator first.
The AHC guide thread has tons of great detail and lots of useful information from folks who have done it before if you can handle the sheer volume of info in there.
