Test Procedure

WARNING: To prevent personal injury, safety goggles should be worn at all times when performing any test procedures on power steering system.
  1. Check power steering pump drive belt tension and adjust as necessary. Disconnect high pressure power steering fluid hose at discharge fitting of power steering pump. Connect hoses, Special tool (6713), from (6815) analyzer kit, and Special Tool (6905), from (6893) adapter kit, to Power Steering Flow/Pressure Analyzer, Special Tool (6815), as shown. Connect adapter, Special Tool (6865), to hose (6713), mounted on flow/pressure analyzer.
  2. Then, connect adapter, Special Tool (6826), to hose (6905), mounted on flow/pressure analyzer. Connect adapter, Special Tool (6865), leading to inlet port of flow/pressure analyzer, to discharge fitting on power steering pump. Connect vehicle's pressure hose which was removed from power steering pump, to adapter, Special Tool (6826), leading from outlet port of flow/pressure analyzer, Special Tool (6815). The Analyzer, Special Tool (6815), is to be installed in series with power steering pressure hose, between steering pump and steering gear. It must also be installed so fluid flows in correct direction through analyzer.
  3. Completely open valve on analyzer before starting engine. Start engine and let it idle long enough to circulate power steering fluid through analyzer and remove all air out of fluid. Shut off engine and let fluid level stabilize in reservoir. Check fluid level in power steering pump reservoir. Add fluid as necessary to obtain proper level. Restart engine. The analyzer gauge should read below 862 kPa (125 psi). If not, inspect hoses for restrictions and repair as necessary. The initial pressure should be in range of 345-552 kPa (50-80 psi).
    CAUTION: The following test procedure involves testing maximum pump pressure output and flow control valve operation. Do not leave valve closed for more than five seconds as power steering pump could be damaged.
  4. Close analyzer valve fully three times and record highest pressure indicated each time. All three readings must be above specifications and within 345 kPa (50 psi) of each other.
    NOTE: Power steering pump maximum relief pressure is 8275-8975 kPa (1200-1300 psi.).
    • If power steering pump pressure's are above specifications, but not within 345 kPa (50 psi) of each other, replace pump.
    • If power steering pump pressure's are within 345 kPa (50 psi) of each other, but below specifications, replace pump.
    CAUTION: Do not force power steering pump to operate against steering stops for more than 5 seconds at a time, power steering pump damage will result.
  5. Fully open valve on analyzer. Turn steering wheel to extreme left until wheel stops, then reverse motion until wheel stops in extreme right position. Record highest indicated pressure at each position. Compare readings to specifications. If highest output pressures are not same against either stop, steering gear is leaking internally and must be replaced.
