CAUTION:
DO NOT
hold valve closed for more than 5 seconds as pump damage may result.
- With belt tension correct, disconnect power steering pump pressure hose. Keep hose end raised to prevent fluid loss. Connect pressure hose of power steering pressure gauge to power steering pump fitting.
- Connect a second pressure hose from valve side of tester to steering gear inlet. Open valve fully and run engine until fluid obtains normal operating temperature. Check fluid level. Add fluid (if necessary).
- Note pressure reading with engine idling and valve open. On all models except Chrysler Corp. FWD, pressure should be 80-125 psi (5.6-8.8 kg/cm2 ). On Chrysler Corp. FWD models, pressure should be 30-50 psi (2.1-3.5 kg/cm2 ).
- If pressure is in excess of 150 psi (10.5 kg/cm2 ), check hoses for restrictions and check poppet valve (in steering gear) for proper assembly.
- On all models, close tester valve fully and re-open 3 times. Record highest pressure noted each time valve is closed. If pressures are within specifications and range of readings is within 50 psi (3.5 kg/cm2 ) of each other, pump is operating satisfactory.
- If pressures recorded are high but do not repeat within 50 psi (3.5 kg/cm2 ), flow control valve is sticking. If pump performance is to specifications, turn steering wheel to both stops with valve open and note highest pressures.
- If pump output cannot be met in either side of gear, gear is leaking internally. Shut off engine. Remove tester. Reconnect hoses and recheck fluid level.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
