Literally had my 81 FJ40 for less than 3 weeks and I may have screwed up. Need help from anyone who can get me out of a bind. Here's what happened:
1) The FJ I have as a JT Outfitters power steering conversion - with rebuilt FJ40box, toyota pump and such. FJ was working perfectly fine as of 3 days ago, but noticed some slight seepage from one of the lines that goes into the box. AFT fluid was low - so off to Napa to put some conventional Valvoline DEX/MERC ATF fluid (PO used non-synth when he sold this to me and said it was conventional) into the reservoir and tighten up the nut for that line. Brass washer for that Possibly needs to be looked at later.
2) Filled up when cold to the cold markings, turn FJ over and makes some groaning noises after 3 min warm up - pull out of garage and steering groaning badly. Steering wheel struggling at full turns when groaning. Video: https://youtu.be/Q8Z6beR_oow .... Never seen this before. Stop engine - look in reservoir and red fluid looks to be foaming up and no longer clear.
Did I use the wrong type of ATF fluid?? I was certain that this would work, but maybe not.
What do I do to get this corrected?
I am certain it is not the pump here and feels like something with the pump - maybe the wrong fluid?
I am not sure how to drain and flush the PS system but if this is the way to go, is the pump ok if I used the wrong type of ATF?
Please help - I feel like an idiot here and just not sure why this is happening.
