Start engine and run at 1000-1500 RPM until engine reaches normal operating tempera-
ture.
4.
5.
Close test gauge valve just long enough to obtain maximum pressure reading.
Close and open valve 3 times. Record highest pressure reading attained each time.
a. If pressure readings are between 1150 and 1250 psi (7932-8621 kPa) and are
within a range of 50 psi (345 kPa), the pump is within specifications. If the pump
tests OK, but system pressure was low (as tested under “Power Steering System
Pressure Test,” see “Index”), proceed to “Booster Cylinder Test,” see “Index.”
b. If pressure readings are between 1150-1250 psi (7932-8621 kPa), but are not
within a 50 psi (345 kPa) range, the Power Steering pump flow control valve is
sticking or pump hydraulic system is dirty.
c. If pressure readings are constant, but below 1000 psi (6897 kPa), replace Power
Steering pump.
