2002 Disco II

So my project for this coming weekend is to finally replace my leaky power steering pump. I ordered a new pump on ebay for $98 Bucks (Sweet Deal). But, I forgot to get Power Steering Fluid and I Know form all the vids I've watched and all the post I've read you MUST use Land Rover A.C.E. fluid or else your Disco will Explode right there on the launch pad killing everyone for miles around. So, I made the dreaded called to my local dealer and ask the price for this liquid gold. His answer just 49.50 per quart! Are you
F#@$&$! KIDDING me, I said in total disbelief, the fluid is going to cost me more than the new pump did! Yep, that sounds about right, he said.

So later today I'm reading my official handy dandy Discovery Work Shop Manual and on page #57 under lubricants & fluids it says the steering system uses good old fashioned ATF. Dexton II ATF to be precise. Which I can buy a 55 GAL drum of for what they want for a quart of the Land Rover stuff.

So, my question is who's right?

 

I've seen the ATF suggestion and I have seen people claim that it diminishes seals faster.....
I use regular Lucas power steering fluid in both ace and for steering. No issues

 

x2 power steering fluid in both ace and for steering

 

Page 57 means you're looking at the D1 manual, not the D2 manual.

the same section of the D2 manual says:

PAS fluid
Use Texaco cold climate power assisted steering fluid PSF 14315.

ACE fluid
Where ambient temperature falls below -20° C (-4° F), use only Texaco cold climate power assisted s teering fluid PSF 14315. Where ambient temperature remains above -20° C (-4° F), use either Texaco cold climate power assisted steering fluid , Dexron 11 or Dexron 111 non-synthetic fluid.
