A power steering pump fluid/filter system which utilizes a combined cooler, filter and reservoir that is positioned preferably in front of the radiator and which provides the three functions of reservoir, cooler and filter. The reservoir comprises a body of material such as magnesium or aluminum and has integral cooling fins. The body includes two openings in the base which permits ready connection to the two hoses of the power steering pump. The combined cooler, filter and reservoir also includes a cover typically made of magnesium or aluminum and a cap having a twist lug connection to the cover. The cap supports a dipstick for measuring the level of the oil.
