Power Steering System Test - Isuzu 1999 RODEO Workshop Manual

2A–10 POWER–ASSISTED STEERING SYSTEM
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch
conveniently on the column.
3. With the column mounted lock, the ignition and
steering operation can be locked to prevent theft of
the vehicle.

Power Steering System Test

Test Procedure
Legend
(1) Fluid Reservoir
Test of fluid pressure in the power steering system is
performed to determine whether or not the oil pump and
power steering unit are functioning normally.
The power steering system test is used to identify and
isolate hydraulic circuit difficulties. Prior to performing
this test, the following inspections and corrections, if
necessary, must be made.
f Inspect pump reservoir for proper fluid level.
f Inspect pump belt for proper tension.
f Inspect pump driver pulley condition.
and lock are mounted
The column can be disassembled and reassembled.
However, to insure the energy absorbing action, use only
the specified screws, bolts and nuts as designated, and
tighten them to the specified torque.
Handle the column with care when it is removed from the
vehicle. A sharp blow on the end of steering shaft or shift
lever, or dropping the assembly could shear or loosen the
fasteners that maintain column rigidity.
(2) Power Steering Unit
(3) Power Steering Pump
1. Place a container under the pump to catch the fluid
when disconnecting or connecting the hoses.
2. With the engine NOT running, disconnect the
pressure hose at the power steering pump and install
power steering tester J-29877-A. The gage must be
between the shutoff valve and pump.
shutoff valve.
3. Check the fluid level. Fill the reservoir with power
steering fluid, to the "Full" mark. Start the engine,
then turn the steering wheel and momentarily hold it
against a stop (right or left). Turn the engine off and
check the connections at tester for leakage.
