Thanks.

Sounds like a lack of anti-foaming properties could be an issue for your situation. (If your fluid is forming an aerosol in the tank.)

I purged it today and I filled it with RP, but need to jump start it to get it running to continue the bleeding of the air in the system. Probably do that this weekend some time if I have time.

What to use in the PS fluid really depends on the car. But, I'm not surprised that ATF finds its way into PS systems. My 1997 Lincoln Conti called for Mercon ATF in the PS and Transfer case/transmission. I ran that car for 230K miles and doubt I changed the PS fluid more than once or twice. It operated flawlessly as there was never a repair to the power steering system, even after 12 years. My current 2002 Conti calls for Mercon in the PS fluid and Mercon V in the transmission/transaxle. I used Mercon V in both to make it easy...and it's a semi-synthetic.

Now since my 1999 Camaro calls for power steering fluid, that's what I use. Still, there are some pretty potent ATF's out there, especially the Redline D4, Amsoil ATF, Honda DW1, Mobil 1 ATF, etc. All have strong chemical add packs as ATF's go. I suspect they probably have stronger add packs than generic power steering fluids. I know people have used Mobil 1 ATF in their PS systems since as long as it's been available, without any issues. Before I condemn something for not being able to do the job, I'd want to do research into it. The data is out there for those willing to search a bit.

My 1999 M6 has 18K miles on it and a 800 rpm hot idle oil pressure of 40-48 psi has been about the norm. On the hottest of summer days I can say it's dipped into the upper 30's. And in shifting from M1 5w-30 to M1 0w-40 I'd say the oil pressure runs about 2 psi higher now....not very noticeable though. And with the lousy oil pressure gauge who can really say?

Antifoamants or foam inhibitors (Protective Additive): polymers such as silicone polymers and organic copolymers of the silaxane's; creates a lens that reduces the bubble's surface tension......from Molakule concerning ATF additives.

My 1999 M6 uses conventional ATF. I would think that anti-foaming agents are a requirement in a gear box too.

Right. There are many different ways to design a pump and not all P/S pumps use the same design. They cavitate fluid in different ways, have different seals, etc. The manufacturer of the pump will direct what to use and will know what is needed.

Plan it to mount cooler just like everyone else has, center cut right behind the air dam about an inch away from the dam itself.

Got the following cooler:

Derale Frame Rail Cooler 13224 series 7000

picture is here:

specs are here:

I will be doing a complete flush before installing the cooler, any personal opinions on fluid type, brand and amount (assuming the cooler holds larger amounts of fluid)?

Car is 1997 camaro z28 with 75K miles.

Anything special to installing it?

Any special fittings? Some say the barbs leak?

Excellent. That's what I currently have and it has held up well.

It would hold less than 8 oz of fluid but I don't think you'll notice the volume if you are doing a flush. The amount needed for a flush will be highly variable depending on your helper and how quick you are to shut things off. I usually buy a bunch of small bottles of fluid from a local store and return whatever I don't use.

As long as you don't have a special/fancy P/S pump that requires a custom fluid, any regular power steering fluid would be fine. Given the issues we seem to see with old/dirty fluid boiling over in the tank, there might be a case here for investing in synthetic power steering fluid, as well.

Have royal purple on hand full synthetic EZMAX ready to go! Someone stated I needed a barb x barb connector fit as the cooler doens't match the oem lines on the P.S. pump?

blk97z28

believe the 13225 has screw in fittings where the 13224 has no screw in fittings but you use hose clamps and clamp the hoses on correct? I've already ordered the 13224, should that be ok without having the screw in fittings like the 13255 offers?

blk97z28

iTrader: (3)

Still the case with these units? Any possible way to run the same dia hose all the way down and not have to use connectors till the very end? Where are you installing these couplers high in the line or near the cooler?

What about using Derale part $ 13225 with the -6AN male fitting, then buy two female -6AN fittings with 3/8'' barb on one end. Then just run 3/8'' hose the entire time and not worry about using any connectors? Just thinking out loud here, would the seal between -6AN male and -6AN female be tight enough?

I added a finned power steering cooler, and upgraded to better fluid and lowered the level to the cold Mark with a hair tie around the brand new cap in a new reservoir. I still get wet cap and reservoir after autocross. At least it's not venting onto the inner fender anymore. I have an all Aluminum radiator with tranny cooler ports I'm not using (m6) should I tap into that cooler also?

Which one? Where did you mount it.


Probably not. I would think that there is an issue with your current setup or it's in a position where it can't do it's job.

For autocross, a autozone finned cooler is junk. Adding one for a DD will make you feel better but start racing with it and you will spit fluid all over the place.

B&M stacked plate with 1/2" inlet and outlet, Redline fluid with stock reservoir/cap and I have no issues.

Is what I'm using mounted underneith. nothing in front of it in the return line. I'm also not using a rack I'm using a old power steering gear.

There are details in the instructions.

That cooler needs to be in forced airflow:

https://derale.com/images/stories/vi...pdfs/13200.pdf


In order to be out of the airflow, you'd need one specifically designed to be a "frame rail" or remote mount cooler. They are larger, have more surface area, have a different fin design, etc.:

That cooler will be severely restricting and most likely cavitate the fluid. It necks down smaller than 3/8" at inlet/outlet.

Ruffturbo911

The barbs should be fine. Did mine with some permatex sealant and worm drive hose clamps. Not a drop leaked.

It's receiving forced air once it's moving. there is no cooling fan on it. It looks similar construction to the other derale power steering coolers. I've read allot about the turn one pumps.

This is what I use, along with TurnOne modified pump and Redline PS fluid.
