Cheers rob, that makes sence looking at it. The reason for asking is I\'m thinking of using a cooler for my power steering fluid. Think what i mite do is turn it upside down so that the feed/return is at the top and allow air to get out easily.

Maybe lol, shame as I have this sitting ready. Do yous know what sort of temp the powersteering fluid would get to? Would it be enought to close the thermostat in an oil cooler?
