Autocrossed this weekend, and noticed between runs that my power steering fluid reservoir was bubbling like a coffee perculator. I didn't have any way to check the temp so I don't know if it's air in the system or temperature. It would calm down before the next run. I didn't notice any change if steering feel while on course. Anyone ever run a cooler for that. If it is boiling I can't imaging that's a good thing, so I want to change the fluid to a higher temp fluid.

Any suggestion/tips would be greatly appreciated.

 

You might try changing it for a FRESH fluid, but higher temperature-rated fluid is not likely the answer. FIRST change it all out for fresh fluid. THEN if it still boils, get an aftermarket cooler for the PS oil. This question has been asked before:

Mine is made by Hayden, but here's a handy link to a different one http://www.amazon.com/Derale-13200-P.../dp/B0006HNM66
