Pump Flow Rate Test

WARNING: This page is about a different car, the 1993 Ford F-Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install Power Steering Analyzer (014-00230). See Figure . Allow power steering fluid to cool to 130°F (55°C). With engine at full governed RPM, close shutoff valve. Flow should read zero. Quickly open shutoff valve; flow rate should immediately return to normal.
  2. Repeat this test once, but DO NOT  allow fluid temperature to exceed 200°F (93°C). If flow rate does not immediately return to normal, repair or replace pump.
