So I know there are some major differneces in the good brake fluids....

So what is a good Power steeing fluid to use ???

ATF ?
GM ?
Valvoline synth. ?
Redline synth. ?

I'm getting ready to put a new pump on, and add a cooler, so I will be pretty much filling the system with new fluid...

Oh and this is a 3rd gen application if it matters...

Redline synthetic plus OE PS cooler (4th gen).

I run synthetic ATF and usually Red Line D4 ATF but have been known to use Mobil 1 ATF in a pinch.

Redline PS fluid. Some say it's the same as Redline ATF, but I use their PS fluid anyway.

I've had decent experience with the Valvoline Synthetic. I completely bleed the system every year.

Reasonable price, and readily available everywhere in the quart size.

Bock

Valvoline Synth. I hardly ever mess with it, just use a turkey baster to suck out the old stuff and fill with fresh fluid a few times a year. With an underdrive pulley it's not as big an issue.

Well I don't have a underdrive v-belt pulley, but my 383 rarely see over 6000 RPM, and I've added a small Perma-cool fin/tube type cooler behind the headlights...

So I think I will stick with Vavoline Synth. I can get it anywhere and it has worked for me in the past.....

Valvoline synthetic plus OEM P/S cooler going through a Turn One pump.

Redline with OEM cooler and pump to this point, but I am dropping the OEM cooler to put less heat into the radiator while adding a turn one. Still plan to use Redline forever.

Redline PS and Turn One Pump. Jeff is the guy over at Turn One, had a good talk with him yesterday about some issues I am having right now with my steering set-up. It is highly unlikely they have anything to do with his pump, so far no-one to date has had one fail. He would fix it for free if there was some defect anyway, and will dyno any of his pumps for $25 if you think there may be an issue. Something is to be said for customer service like the way Jeff does it. Two thumbs up, way up!!!!

Royal Purple PS fluid.

stock pump, underdrive pulley, valvoline boiled over all the time. stock pump, underdrive pulley, aftermarket ps cooler and valvoline did great all year last year till my last run at mid-ohio in august (hot), the fluid boiled over. this year im trying redline, if it still boils over, I guess its turn one. And I don't rev past 5500 unless Ive got a good reason.

I am about to buy a turn one pump. I've been using valvoline. Will I need to add a cooler?

When you call there, I'd be real interested as to what Jeff would say about that. Since mine is in a race app I run a cooler just to be on the safe side. He won't say anything but use a GM type fluid, I already asked that question.

Well I got the ATSCO re manufactured pump installed and the small cooler hooked up and filled the system with Valvoline SYN

On a side note I spent 4+ hours trying to get a MARCH brand P/S bracket setup to work.... the part is suppose to be for 79+ cars with metric P/S pumps (like mine)... even after EXTENSIVE fabrication / modification the stock brackets were put back into use... DAMN AFTERMARKET PARTS sometimes !!!

In my V6 I have a Turn-one pump and run Redline PS fluid with no cooler (also have a much smaller steering wheel than stock). Much better than stock pump for autocrosses. For track sessions the fluid gets hot but does not boil. Plus no more whiney pump! to the stock pump... Turn-one pump =

I use a GM P-pump with a 60-series pump ring, and a speed-sensitive metering rod from an old early-nineties Holden application, called the "Code W"metering rod. Otherwise known as a droop flow application, as the flow control valve drops down the bore, the taper on the droop flow metering rod begins pinching off fluid flow in order to restore steering feel. Thus, I get a nice, solid steering at high RPM while also getting maximum assist at low RPM, where I need it most.

Steering cooler is sourced from an early nineties FWD Oldsmobile, I think an Achieva. It sits behind the radiator on the LH side of the car, and it works great. I used to have a ZR1 steering cooler but it was big overkill and didn't fit very well anyway...

Ask Jeff at Turn One if he remembers a certain Delta College co-op student called Dan Burk, who worked with him in the pump dyno room back in 1991 through 1993....
