All of the threads I can find that detail how to do this say to siphon from the reservoir.

However, on my 2017 I don't see how it will be possible to get a hose down into the reservoir to properly get it all siphoned out? See the picture below for reference, but as far as I can tell, there's no way I'll get a hose down in there.

Do I just disconnect the return hose and drain it that way? If so, which line is the return?

TIA!

 

Here is the ghetto way... Yes pull off the return line. Drain the reservoir. If you're alone stuff a soda bottle down there and stick the return line in the bottle. Get in and start the car for about 5 seconds. Don't run it much longer or you will suck air. (very bad) Get out and reattach the return line and refill. Repeat this ridiculous process a few times and you are done. Make sure you get the expensive crap from the dealer. It's the EPS steering fluid fluid or whatever they call it. Its like 20 bucks a quart. (sons o *****es)

 

Leave it to Nissan to add this integrated cap with no holes or slots big enough to siphon anything out of the top lol. Thanks for the tip!

I bought the correct fluid and have just topped it off for now. I assume I have a leak so will just monitor the level over the next few weeks and then reassess then.
