(4) Unscrew the tube nut and disconnect the
power steering fluid pressure hose from the power
steering gear (Fig. 4).

(5) Connect the vehicle's power steering pressure
hose to Adapter Fitting, Special Tool 8185-2, con-
nected to the analyzer (Fig. 5). Tighten the tube nut
to a torque of 47 N·m (35 ft. lbs.). Route the hoses
away from the exhaust system as well as possible.
(6) Connect Adapter Fitting, Special Tool 8185-1A,
which is connected to the analyzer outlet hose (valve
end), to the power steering gear port (Fig. 5). Tighten
the tube nut to a torque of 47 N·m (35 ft. lbs.).

(7) Being careful not to kink or pinch the analyzer
hoses, lower the vehicle to the ground.
TEST PROCEDURE
(1) Completely open the valve on the Power Steer-
ing Analyzer flow meter.
(2) Start the engine and let idle long enough to cir-
culate power steering fluid through the analyzer and
hoses, until the air is out of the fluid. Shut the off
engine.
(3) Check the power steering fluid level and add
fluid as necessary. Start the engine again and let
idle.
(4) The analyzer gauge should read below 862 kPa
(125 psi). If above, inspect the hoses for restrictions
and repair as necessary. The initial pressure should
be in the range of 345-552 kPa (50-80 psi). The flow
meter should read between 1.5 and 1.7 GPM.
CAUTION: The following
involves testing maximum pump pressure output
and flow control valve operation. Do not leave valve
closed for more than five seconds as the pump
could be damaged.
NOTE: Power steering pump maximum relief pres-
sure is 9308 to 9998 kPa (1350 to 1450 psi.).
(5) Close the flow meter 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.
