Re: What is in my hydrolic fluid?

Its a white color. It came out of my power steering. My brother put
some in his vacume chamber and thought this would take the air out of
the fluid. I had told him I thought it was air mixed with hydraulic
fluid. Didn't work. Next he heated it to 140degrees and tried again.
Nothing but a small layer of clear fluid on top. He now thinks its
water. So how can we figure this out without any fancy equipment.
Should we raise temp to boiling point of water? But would this tell me
what it was air or water? If we could get this clear fluid out of there
is there a test specific for water.

Anhydrous copper(II) sulphate becomes blue with water, but absolutely
certain characterisation probably needs a physical measurement of some
kind.

recources are limited.
