Borgeson Update

What oil do you use?
Quite sure to say your oil gets too thin once hot, either change fluid (depends on what you use atm) and/or add a cooler.
I used “ power steering fluid” from O’Reillys. Their brand. Any brand you like ?

They recommend a GM style power steering fluid, check their site as it is mentioned somewhere.
 
I use Redline oil with a PS cooler. Oil stays cool. No noises either.
 
Interesting. Borgeson specifically recommends against Redline saying that it can foam. Maybe your cooler is helping.
I just got off of the phone with Borgeson Friday about my leak and they told me I can run any power steering fluid in it as long as it doesn’t have some kind of stop leak in it but In saying that I run this that O’reily sells.

The cooler did the trick. No issues with assist fading after use, and the fluid stays cooler. I used a Derale cooler P/N 13309. Inexpensive, compact, and it does the job. Comes with AN6 fittings installed.

BTW I have not noticed any strange noises (hissing, etc) coming from my Borgeson unit. Very happy with the conversion, and no leaks.

This is great to hear. I got a Derale 13224 installed but other parts of the front end are still not done. I think it will work out great.
 
Hello all,

Just a month or so ago I installed a Borgeson power steering box in my '68 B-body. I retained the existing Saginaw power steering pump. The other day the weather allowed me to take it out on an extended cruise up and down a local mountain highway. The steering feel was more precise than the previous Firm Feel unit, BTW. Just before I got back home I noticed a reduction in power steering assist. Upon pulling into the garage I checked the temperature of the power steering pump, and it was nearly 200 degrees.

It dawned on me that some folks noted a loss of power assist if the fluid gets too hot. I also recalled that Borgeson recommends a power steering cooler. I had thought this might only be necessary if I did autocross or something of that nature. Clearly that was a wrong assumption. So I have a universal style cooler on order and will install it in the return line from the box to the pump; I would expect this to solve the problem.

Just an FYI for those who might think they don't need a cooler.
I used the full Borgeson kit with their pump. I burned my hand on the pump and thought I brushed against a header tube. If I recall, the infrared gun indicated close to 240 degrees Fahrenheit. I got this cooler from Summit and machined a small bracket, currently the pump body shows 175 degrees on a warm day and a long drive.IMG_0040.jpg
