    My first thought was that he might've failed to sufficiently torque the shock top nuts with the wheels down.

    Your inbox is full tried to PM you! Anyways I figured I would ask how much track time you have on the PS cooler? Mine exploded after 4 HPDE sessions at Laguna Seca on Sunday. I'm concern this cooler really may not be adequate, either that or I got a faulty one.

    Do you have pictures of how it failed.

    Anybody have any idea what kind of pressures the Power Steering system can generate?

    The power steering pump specification in the Service Manual (pressure relief) is 1,640 to 1,740 psi.

    Its not visible but you can just see the bottom portion of the cooler drenched in PS fluid as well as the underside of my car. There is no fluid anywhere upstream of the cooler either.


    I will probably be switching to a cooler like this:

    Well that is the specification. Since it is the "relief" spec it likely contemplates "spikes." For the purposes intended here, I suspect all we really need to know is that power steering systems operate with at pounds of pressure in the hundreds and therefore, are high-pressure as opposed to low pressure systems.

    Finally, the pressure ratings are at the output side of the pump (pressurized-line) and not at the return-line side where the pressure would presumably be substantially reduced.

    I guess I'm just suprised this system runs at such high pressures. Knowing this now I don't think the faq recommended cooler is adequate for such pressures which is likely why I had an issue.

    I thought that others had tracked their car with the one in the faq. No? I will be holding off on this now. Thanks onefastv.

    That's what I am trying to find out. It may just be a one off failure but I haven't heard anyone else's track experience with it.

    The PS cooler should basically be at ambient, since it's in the return line to the reservoir and the reservoir is vented to atmosphere.

    I, too, would be interested in seeing pics of the failed cooler, but I have to think it was just a faulty cooler. There are tons of OEM PS coolers on all sorts of vehicles and none of them are anything special / heavy duty.
    '05 Stealth Grey CTS-V, Hyper Silver Linea Corse Venetos w/Continental ExtremeContact DWs (summer), black Team Dynamics ProRace 1.2 wheels with 275/35-18 R-compounds (track), Hyperblack Rota Torques (winter), KW Variant3s, V2 front brakes, Hotchkis rear sway bar, EPS cam, TEA-ported 243 heads, FAST92 intake w/LS2 TB, JBA Camaro/G8 1-3/4" shorty headers w/JBA cat pipes, Corsa exhaust, UUC motor and tranny mounts, UUC shifter, MAPerformance trailing arms, Specter cradle bushings, etc...

    Is the hose routing on the power steering important? I would not think so but wanted to confirm.

    Here is what the cooler looks like now. you can see the area where oil has soaked the cooler but there is no apparent gross leak, it is definitely a fine leak.
