What type of power steering fluid does the 2001 ford f250 use?

The 2001 Ford F-250 uses Mercon V power steering fluid in the system. Your power steering system uses hydraulic fluid to move from the pump to the steering box to help aid You in turning so it is lighter. You should make a point to check Your power steering fluid every time that You change Your oil to make sure that it is full. Low power steering fluid can lead to a loss of steering feel and it could make Your steering very heavy. Never mix different types of fluid in Your vehicle because it can change the boiling point. Hydraulic fluid is under a lot of pressure and that can create heat that could boil and cause damage.
