DESCRIPTION AND OPERATION
POWER STEERING PUMP OPERATION
Hydraulic pressure for the operation of the power
steering gear is provided by a belt driven power
steering pump (Fig. 1). The power steering pump is a
constant flow rate and displacement vane type pump.
The power steering pump used on all applications is
the Vane-Submerged remote reservoir style power
steering pump.
Fig. 1 Vane Submerged Remote Reservoir Power
The remote reservoir type pump (Fig. 1) has the
pump housing and internal components combined
with the fluid housing. But it has a remote reservoir
for the power steering fluid supply.

DIAGNOSIS AND TESTING
POWER STEERING PUMP FLOW RATE AND
PRESSURE TEST
The following procedure can be used to test the
operation of the power steering system on the vehi-
cle. This test will provide the flow rate of the power
steering pump along with the maximum relief pres-
sure. 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 (Fig. 2).
