DIY: Steering fluid flush

Hi all,


Today I did a steering fluid flush on my 2015 murano, other years should be the same within the 3rd generation.


The service manual, does not tell you to replace it at any specific interval, but to inspect and change as needed every 20,000 miles.


I have never changed my steering fluid, just top it off. And boy was it dirty after 100,000 miles, it looked really dark, and was long due for a change. IMO, the steering fluid should be flushed every 30,000 miles. Color of new OEM fluid looks like olive oil.



I saw some videos on youtube where the easiest way is to use a turkey blaster, and suck the fluid out from the reservoir. But that method will not work on the murano, since there is a mesh on top of the reservoir that prevents you to stick anything inside. I guess Nissan does not want you to use that method.
So the only way to change it is with this method below.


Very easy, just a couple of tools you can find around the house, and should not take more than 1hr.


This method relies on pumping the fluid out through the return line by turning the wheel from lock to lock while the car is off, and adding new fluid as the old one is flushed out.


I illustrated this method with some picture


CAR SHOULD BE OFF... (IMPORTANT)

1- First you jack up the car, so both front wheel are off the ground, this will make it easy to turn the steering wheel.

2- Disconnect the return line and connect it to a drain hose going to the an oil pan.

Only a little fluid will come out, so just use a small cup to catch it.

3- Secure the other end of the return line on the reservoir side.


4- Turn your steering wheel from lock to lock. As you turn the steering wheel, you will see the old fluid being pumped out. Do one full turn lock to lock (turn all the way to the right and all the way to the left). Then go and fill the reservoir with new fluid. Repeat 3 to 4 time to flush all the old fluid out.


Note:You will hear a loud whining noise coming from the pump as you turn the wheel, this is normal and has nothing to do with the fluid being dirty.

Thank you for sharing. Well documented and easy to follow.


A few questions:
Instead of turning wheel is it possible to use vacuums pump and suck all old fluid? Will it work?

Should I worry getting air ? Does it work like brakes and need to be very careful not getting air in.

How many bottles of new fluid did you use for flushing?

Hi @dand.


The power steering fluid capacity is 1l, the bottle is a little less than 1l (946ml), I used 1.5 bottle.


I guess you could use a vacuum tied to the return line and suck out the old fluid as you add new fluid in the reservoir, but turning the wheel has the same effect though.


To my surprise, I did not introduce any air, and I was doing it alone. I did not let the system run dry, I did one lock to lock turn, and went to fill the reservoir, and repeated until clear fluid started to come out the return line. Ideally, you can do this with 2 persons, the other person will fill in the reservoir as you turn the wheel slowly, this way you can be sure there will be no air introduced.


And that is the reason you do not want to do this while the car is running, because you run the risk of running the system dry of fluid while the pump is operating. With the car running, a slight turn of the steering wheel will cause the fluid to rush out at a very high rate.


Because of the mesh on top of the reservoir, it is hard to get a good sample of the fluid and check how dirty the it is, and you cannot tell just by looking on top of the reservoir. Mine was so dirty, it was ridiculous...

Assad,
Again, thank you for sharing this method with us, just finished the flush.
Had some fluid escaped when return was disconnected. Had a hard time to clean, still some fluid down there.

50K miles fluid vs new.

Yours looks as dark as mine, definitely not good for the pump, glad you changed it.

That's why I had the cup underneath to catch any fluid coming out. I have also seen some people lay a rag underneath to catch the oil, I think that is a better option.
