POWER STEERING PUMP FLOW RATE AND PRESSURE TEST
The following procedure is to be used to test the operation of the power steering system on this vehicle. This test will provide the flow rate of the
power steering pump along with the maximum relief pressure. This test is to be performed any time a power steering system problem is present to
determine if the power steering pump or power steering gear is not functioning properly. The following pressure and flow test is performed using
Pressure/Flow Tester, Special Tool 6815, or equivalent.
PROCEDURE
1. Check power steering pump drive belt tension and adjust as necessary.
2. Disconnect power steering fluid pressure hose, at power steering pump. Use a container for dripping fluid.
3. Connect the inlet hose on the Pressure Gauge, Special Tool 6815, or equivalent using required adapter, Special Tool 6972, or equivalent to the
pressure fitting on the power steering pump. Connect the pressure hose which was removed from the power steering pump, using required adapter
fitting, to the outlet port of Pressure Gauge, Special Tool 6815, or equivalent. Pressure Gauge, Special Tool 6815, or equivalent is to be installed
in series with power steering pressure hose, between power steering pump and steering gear. It must also be installed so it is in correct direction of
the fluid flow.
4. Completely open valve on Special Tool 6815, or equivalent.
5. Start engine and let idle long enough to circulate power steering fluid through flow/pressure test and get air out of fluid. Then shut off engine.
6. Check power steering fluid level, and add fluid as necessary. Start engine again and let idle.
7. Pressure gauge should read below 862 kPa (125 psi). If above, inspect the hoses for restrictions and repair as necessary. The initial pressure
reading should be in the range of 345 - 552 kPa (50 - 80 psi). The flow meter reading should be between 4.9 and 5.3 liters per minute (1.3 and
1.4 GPM).
CAUTION: The following test procedure involves testing power steering pump maximum pressure output and flow control valve operation. Do
not leave valve closed for more than 5 seconds as the pump could be damaged.
8. Close 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 8240 - 8920 kPa (1195 - 1293 psi.).
