Intermittent P/S

[Gordy_Schesel at allianzlife.com]

I had a related problem some years ago at about 125k miles.  PS was not
failing but I was getting warning of low reservior during autocheck.  The
problem turned out to be foaming of the Pentosin in the reservior causing
it to overlow out the top.  Problem resolution was replacement of the
"leaking" pressure hoses between the pump and the reservoir.  I do not
remember, if it was both hoses, however.
