    Replaced power steering pump, hoses, lines, reservoir and gear box and still over heats. Was instructed to use oil instead of power steering fluid and told it wouldn't create that issue. All these things are new and still over heats. Any suggestions

    If you changed out the reservoir, did it have an oil filter in there? And if there was, did you change that?

    What is this on ? And every system has a filter as asked in the post above did you change the filter ?
    I mean it sounds like you just started throwing parts at it
    It very well might be you have a internal leak in the the steering cylinder its self which might cause the oil to over heat ..
    More info would be helpful

    Power steering cooler on the truck? Dirty?

    @jamespmack mentioned a long time ago about a corroded ground cable causing the electrical system to ground using the hoses.

    Flow restriction. I question filter change also.

    Seen it on FL, melting High PSI hoses.

    We need more info.

    What kind of oil?

    Not motor oil?

    Use a good hydraulic or AT oil.

    Synthetic atf I all I use in it.. Like 40 dollars a gallon at Napa. Each drop of that #### must be worth like quarter atleast. Don't spill any.

    Most all the newer systems recommend using hydraulic oil
    If its a older system I would stick with ATF myself

    Almost all manufacturers have went to engine oil.

    I've only ever seen engine oil or Dex 3 used in power steering.
