So after wheeling for a few hours power steering basically stops working properly. It will work while I m moving but if I need to turn the wheel while I m stopped it doesnt have the power. I let it cool down...works fine. I have 35s and its a manual. Do I replace with another OEM steering pump or install a cooling system for the fluid. Or Both.........Any help is appreciated.

Hmmm. I think if you replace with an oem one you'll be fine. Never heard of this happening to the oem pump before

You've kinda answered your own question there- if it works after cooling it down then it seems like cooling the fluid would be ideal.

Now if it stops working effectively while you're not in motion but works while you're in motion then you may have some broken vanes within the pump. But you aren't there yet.

Mine would get so hot it would boil the fluid.
Added a cooler and a filter and changed the fluid. That helped a little.
Finally added hydro assist.
If you have boiled the fliud its probably a good idea to change it.

I think your pump is going. It may not be gone yet, but I suspect the fluid has gotten hot and the plastic vanes in the pump have started bending. It won't get better until you put a new pump in. Happened to me when I had the front axle locked (I assume you don't have lockers in your X).

One other thing you might check: Your serpentine belt could be slipping on the pulley. Just speculation on my part, but if you've never changed it or it's been a while, might not hurt to do so.

A cooler will help before i installed PSC, ran the stock pump with a cooler it made a big difference.

I had this exact thing happen to me at Rausch creek. What a bitch!!! Luckily on the highway home it wasn't to bad but pulling into parking spaces, gas stations, making turns etc. Was extremely difficult. After I got back I made an apt. At the dealer and they replaced my power steering pump under warranty, I have had zero problem since.

I know the thread is a little old but I was curious what Coolers you guys are using? I've had the same issue turning my 37's in the rocks, I've had the fluid boil twice. Time to do something about it before the pump goes.
