Idle Pressure Test (All Others)
- Remove high pressure hose at steering pump and connect a spare hose to pump fitting. Connect opposite end of spare hose to Pressure Test Gauge (C-3309E) or equivalent. Connect pressure hose from valve side of steering gear to valve side of gauge. Valve must be installed on outlet side of gauge.NOTE: Replacement fittings are required on Test Gauge (C-3309E) for adapting to "O" ring type hose tube ends.
- Fully open shut-off valve. With a thermometer in fluid reservoir, start engine and warm fluid to 160°F (72°C). Turning wheels from stop-to-stop will aid in warming fluid. DO NOT hold wheels against stop.
- With engine at idle speed and gauge open, check initial pressure. See POWER STEERING PUMP PRESSURE TEST SPECIFICATIONS table. If pressure is above specifications, check for restricted hoses or crimped lines.
