    Many ways to skin a cat, just curious how you did it.

    You guessed it. I used AN-6 hose barb to AN-6 female at the stock hoses. I did this so that if the stock hoses need replaced at some point the OEM hoses will fit without and adaptation.

    Belt and suspenders approach (jack stands & ramps, with the jack still in place) - the installation required me to spend a lot time measuring, fitting, and installing with nothing but my head underneath the car so I wasn't taking any chances.

    Too soon to tell. I don't have a power steering temperature guage and I have not had a chance to go to my (cough) "track".

    Sorry, but a silly question. How do you know you required extra cooling ?

    After hard runs on the back roads I was having to add fluid and when changing the fluid it was dark brown, which according to the Service Manual indicates that the fluid is "burnt". Milky fluid by way of comparison indicates the presence of water/moisture according to the Service Manual. The OEM fluid I use is crystal clear when new.

    I forgot to mention earlier, that is does look real nice. I'm assuming you used the bracket as per the faq to reinstall. The hoses are a nice touch. Did you do that for the rest of the car?

    I could not use the OEM bracket as was done in the FAQ. I fabricated a bracket using the metal stock (some aluminum and some steel) that is readily available from Home Depot. (The pictures show the cooler with and without the brackets). The fasteners are all Grade 8 used with red label Loctite thread locker.

    I think you're drawing a flawed conclusion from the data you gathered and from what Redline told you. Just like the engine, transmission, and diff fluids, keeping the PS fluid cool is going to keep the fluid happy longer. Our engine oil doesn't start boiling until about 600F, too, but that doesn't mean I'd be happy rolling around with temps even half that high. Hell, I'm not happy that my screwed up oil temp sensor shows I'm at 260F!

    When you asked Redline the boiling temperature of the fluid did you bother to ask them what the optimum temperature for their ATFs is? I'd be willing to bet it's not 270F. Just like engine oils, it's probably in the 220-230F range.

    I do not what temperature the power steering pump can endure without harm, but power steering hoses are only rated to 300 Fahrenheit so having fluids with boiling points twice that level is not necessarily responsive to the need to protect the system from potential damage.

    No flawed conclusion. It's only a matter of what question was asked. In this thread there are references by both bdawg and darkman of "boil over".

    My point is that we are not boiling over our fluid. As Brian mentioned it's just spillage from the reservoir. Most of the V-Owners (myself included initially) thought that our power steering fluid boils over.

    No, I did not ask Redline what their ideal operating range was, but easy enough to ask. And I don't argue that additional cooling did not provide a benefit.
