I have a new car and would like to put a filter in the return line on the power steering, to promote longevity of the system components. (The system uses a long hydraulic ram, located under the car.)
At same time, I may want to put in a cooler for the fluid - depending upon whatever advice I get from the members here.
I recognize that the cooler, filter, and the longer hoses could cause flow restriction. I don't know how much the system can stand before it begins to malfunction. But I was thinking that restrictions could be minimized, if necessary, by using oversize hose (maybe 1/2" id) for the run from the ps ram to the cooler, and then two parallel 3/8" runs from the filter back to the reservoir, with only one of the two having a filter inline. The result would be that only a fraction of the flow would pass thru the filter - but that would be enuf.
So, how much am I overengineering here? Is it a total "government job," because the filter is not needed at all. Or is filter and cooler a good idea, and restriction is not of concern?
