power steering leak
why exactly does it boil out of the reservoir?
and will a aftermarket cooler resolve this problem??
The stock cooler cools the fluid to the temperature of the coolant - 210. Not the best - but obviously it worked fine from the factory. So, if you are still cooling the fluid to 210 - it is probably be the fluid itself. So, if you do a complete flush, the problem will likely go away for you.
(The above being said - other rare things that could be at fault, such as a bad pump seal allowing air in. This could cause the fluid to entrain air and swell. If this is happening, your fluid will look milky and frothy.)
But... better cooling should help keep dirty/contaminated fluid from expanding so much. So, changing the cooling is good insurance and will keep you going longer between PS flushes.
I have changed my cooler with some great cooling results. IMO - the reason to do it is not as much for the improved cooling, but to get away from the stock cooler design. The stock coolers failing is a common issue and when that happens, you get cross-contamination between the coolant and PS fluid. Very messy....

Mine has just become mixed officially today, and I'll definitely be buying my own cooler.
- disconnect the overflow tank and clean with dish detergent
- If you can't clean the overflow dipstick, you may need a new one
- use a turkey baster to suck out all the coolant on the top of the p/s tank
- drain the p/s system and refill
(All of the above got me clean as a whistle.)
