well seems if you know where the hose is to know its bad that alone would tell you what you need a wrench to fit the end of hose and turn the nut on end of line til it comes loose then follow hose to other end and remove that and replace same way really no much more can be said about it after you replace it crank car turn wheel all the way one way fill pump turn back the other way few times should pump all the air out... you can find how to replace power steering hose by just typing that you can find how to replace most any car part if you know the name of part even find a video of how one is done sometimes you shouldnt have any problems really its easy as what ive said and you can use autozone wedsite and find many repair info on most cars also
