Hey all,

i have a leaking return hose on my power steering reservior so im going to need to remove all the fluid to chuck in a new one. My only problem is i have no idea how to drain / refill the power steering system and get rid of any air. Everything that comes up on a search has just said remove fluid in reservior with a syringe and then top up... but i need to fully empty my system. Surely it cant be that hard but neither the r33 engine manual or handbook that came with the car tells you anything useful.

help would be much appreciated

thanks

Camden

to drain it, i usually unhook the return hose and run it into a container whilst engine is running, make sure not to turn off engine as soon as the fluid stops running consistently. No need to bleed it, the air will bubble up to the fluid tank, helped by turning the steering lock to lock a few times whilst running.

So while the fluids drains out, you leave the engine running, until the fluid stops? I have the exact problem. And when you put new one in, dont worry about the air? So I just turn on the engine and turn the wheel to get the air out? Please help.

Edit;

I drained my fluid by undoing one of the pipes from the pump to the rack, at the rack and let it drain out (took quite a while). I wouldnt run the engine while draining the system, but maybe i'm just being paranoid.

For bleeding the workshop manual says something like;

-Top up the fluid

-With the engine off, turn the steering wheel all the way to the left then all the way to the right - continue turning back and forth until you stop seeing bubbles. Might as well lift the front wheels off the ground first to make it easy.

-Top up fluid if required

-start the motor, then repeat turning the steering wheel all the way to the left then all the way to the right - continue until you stop seeing bubbles

Then your done. I did this today. My friend looked for bubbles during the last step, but didnt see any. The steering is fine.

I did mine with the engine running without any issues. take off the hose, start the car and turn full lock left to right about 12 times and it should drain out easily.

then connect everything up, fill up the fluid. with the car on turn left to right and u will see it sucks in the fluid in, keep topping it up until full and bubbles gone.

    • Can't remember the last time I saw a good, healthy battery dropping into the 9s during cranking,  Too many variables to say anything about it with any certainty though.  A float voltage of 12-12.2 is tired AF and given how AGMs handle high C rate and DOD, will just die faster and faster with each cold start.   
    • I find most vehicles dip into the mid to high 9 volt range, even with a good battery. Hitting the low 9s, and especially hitting into the 8s is pretty indicative of a dieing battery. The other part to look at is the battery voltage after the battery has been fully charged. They should be sitting at 12.8V, as lead acids are dieing, they head down low and lower. Often getting as low as 12.0 - 12.2. You'll start seeing this when the engine is cranking over slowly. Interestingly, depending on the vehicle, when batteries get really bad, you can see some REALLY funky things going on. From very low voltages, to higher than 16V too. Something I totally didn't expect! This part of the super low and super high voltages I've been seeing on motorbikes, I need to do some further studies on cars. I suspect cars will act a little bit different though for a couple of reasons.
    • Thanks! Supercheap has a sale on this weekend so might be a good opportunity to get a new one. I do have a decent multimeter so I'll give it a try either way.   Hah, you got me! I do not. All I know is that the battery holds charge and sits at an okay level before I start the car. Doing the full charge and rejuvenation cycle on a trickle-charger seems to not really make a difference to the cold start behaviour. I'll try and measure it during cranking and see what it does. It's likely terrible; it certainly feels terrible.  I'll be happy if it is really just the battery and I don't have to dick around with the alternator or starter motor.
    • how do you know voltage is fine?  quick easy test is connect DMM up and put it on max/min mode, remove fuel pump fuse, crank car for 3-5s, go check min voltage You'd be surprised how many "healthy" batteries are showing under 10v during this test in cold weather. 
    • Not properly. You need to be able to dissipate 100 amps or so to doing it meaningfully. You can do it indirectly by watching to see how far the voltage falls during cranking. Unplug the coils or something else to prevent it from starting so you can get a good couple or three chugs. It also helps if you have the multimeter set up reading before you start, and that it has max/min functions. So you can catch the real minimum without having to watch the screen, which often doesn't update fast enough to show the real max/min in dynamic situations. Or use a digital oscilloscope, which can be obtained for <<$100 from Aliexpress (although I'd argue for paying up to ~$200 for a nicer one). A >4 yr old battery will very likely be well down the path to the knackery. Many only last 5-6 years these days. The cold weather lately will definitely make it worse.
