Hydro assist... do you run a cooler?

[BigClay]

Just looking for some opinions from those of you that run hydro assist steering. Do you also run a power steering fluid cooler? What about an extra power steering reservoir?

A friend has a Toyota he put assist on, fluid got really hot w/o a cooler, stays fine w/ the cooler.

My opinion, you can never have too much/too cool power steering fluid.

I run one on the xj. Seems to be a good idea. I do not run an extra fluid res though.

Yes.

Yes, I run a small/medium sized automatic transmission cooler.

I do not run an extra reservoir. I did however cut the neck off the stock pump housing, and extend it about 8-10" with a piece of rubber hose to increase the capacity.

That's what I done as well.

While I don't have hydro assist, I do know my PS gear *loved* the addition of a cooler on the return line!
The fluid used to get hot after an hour (sometimes quicker) on the trail ... pump would groan & whine, steering effort would fluctuate between normal & "Popeye" in a few seconds and the lines would be nuclear hot.
I threw a cooler (8"x12" Ferd tranny cooler from JY) on the inner fender, plumbed it... Steering stays consistent, noise from the pump went way down, & the lines are noticeably cooler.

Could an aux (*sealed*) reservoir be plumbed in on the return side? Pump> box> aux reservoir> cooler> Pump without any issues like air bubbles, etc? Seems the return pressure would be enough to keep it all bled & flowing? (Zero room to extend the the current ham-can)

Ive got hydro assist and hydro boost on my 78 F150. I'm running an aftermarket transmission cooler that is about 8"X10". I'm also using a saginaw P-pump with the chevy van reservoir (off a 95 G20) it doesn't use a filler cap, just a 5/8 nipple to run to the external reservoir. My reservoir came from a 98 E150 though because it holds a little more fluid than the G20 res.

I'm running assist and hydro-boost both so I'm usin a Ford Exploder tranny cooler,filter and second res from a Isuzu Trooper.Whole system holds about a gallon of fluid.I also switched to straight hydraulic fluid.

Well it looks like a cooler for my power steering is on the to buy list
