Power steering flush

Does your Mitsubishi L300 make a strange noise? Need wheel alignment specs?

Power steering flush

Postby joebillhill » Sat Nov 25, 2017 2:12 pm

So I noticed yesterday when replacing one of my steering boots (febest Mb501711 are much easier to work with than beck arnley 1032695 for anyone who's interested) that there was some at fluid on the other boot I had installed. I took a look in my power steering reservoir and lo and behold it was empty.
I'm looking to add more to it but I haven't been able to source any dexron 2. I know they're backwards compatable but everyone always had their views on that... Has anyone used any higher grades and what's been the outcome?
Also I was going to drain and refill the system so I'll know what's in there. The ever so detailed service manual has me disconnecting the fuel cut solenoid connector. I'm assuming this is on the injection pump but where exactly?
Thanks

Any Dexron will be fine (though Dexron 3 has a viscosity closest to Dexron 2). The issue with some transmissions is that later Dexron formulations have different friction modifiers, which messes with the clutches. Not an issue with power steering.

Power steering fluid shouldn't be able to get anywhere near the dust boots. It sounds like your rack has an internal leak. That never ends well.

You can disconnect the fuel cut solenoid by unplugging the large square connector atop the injection pump. I'm guessing the intention is to then crank the starter to push fluid out? Unplugging the square connector will also disable the glow plugs, so that's a bonus. The fuel cut solenoid is a round black thing at the back of the injection pump. It has one wire going to it. There's a white latching spade connector on a tiny bracket you can unplug, but it's a pain to get at.

And here's a picture showing the white single-pin connector- it's the one behind the blue tube cap- if for some reason you *only* want to disconnect the fuel cut solenoid:

Alright I'll get my hands on some dex3 and try to drain and fill. Unfortunate if there's an internal leak. I'll hope for misinterpreting the fluid on the boot but the empty reservoir doesn't bode well...
