Changing Power Steering Fluid

Can be a 6-week job if you DIY. laugh.gif The guys in the US do what they call the "Turkey baster" method. Take turkey baster and suck out as much PSF as possible. Top up with new PSF. Drive for 1 week, repeat. Do for 6 weeks and you will have virtually new PSF.

Most of the power steering hydraulic systems don't have drain plug, you have to suck out the old fluid with a sypring or vaccum tool. Manually filling the system is posssible but chances you have have air trap in the system. To get rid of the air you will have to bleed the system for many times and most of the time you will not have a full 100% solid hydraulic system. Most of the professional mech will use a vaccum air lift tool to help in filling nd removing the air trap in the sytem.

They are not self-bleed systems. So to prevent air bubbles, the turkey baster method is a sure win but you do have 0.0000x% of the old fluid left. The other method is to raise your car with jack stands (front only), turn on (not start engine), unplug the inlet tubing and turn the steering wheel left and right to pump the PSF out (draining from the inlet). To prevent bubbles, you continuously fill the PSF reservoir and not let it drain. A 2-man op much like the old way of bleeding brake fluid.

 

You got to hand it to those USA DIYers. Damn tokong! thumbsup.gif

No need instructions. Just use a turkey baster and suck the PSF out. Then replenish with fresh clean PSF. After a week of driving repeat.

The crazy turn steering wheel method is as follows:

 

1. Disconnect the return line to the reservoir.

2. Drain the reservoir and cap the open connection.

3. Route the return line to a suitable reservoir.

4. Open and line up at least two quarts of new ps fluid for quick pouring.

5. Fill reservoir with new fluid.

(Here comes the fun part:)

6. Have helper turn engine on, and immediately turn steering wheel from lock to lock, all the while you're pouring fluid into the reservoir.

7. Turn engine off.

8. Reconnect return line to reservoir.

9. Top off fluid.

10. Clean up mess.

 

Keep in mind the fluid comes out forcefully during flushing. Lifting the front end so the wheels are off the ground helps reduce the flow to a managable level.

yes... i know...thks...

 

The most xiong part is to turn the wheel lock to lock without the power steering pump working...... [sweatdrop][sweatdrop][sweatdrop]

 

next is to clean up the "bloody" mess..... luckily, the smell is still ok wif me.... some ppl simply cant tahan the pungent smell....

There is another way but don't need to turn the wheel lock to lock.

 

Just unplug the return line, maybe attach a barbed adaptor so you can connect another tube so that you can drain it to a container. Open the PSF reservoir cap, start engine for 5s then turn off. The PSF will flow initially. Top up with PSF. Go back to start car again for 5s, turn off, repeat replenishment until the PSF becomes clear.

 

If you like to do flushing, just get 2qts of cheap generic PSF. Until the 2qts is used up as flush, you fill with synthetic PSF. sly.gif

 

Keep the reservoir from running empty. If the PS pump whines, there is air going in.
