Idle Pressure Test

1999 Dodge and Ram Dakota SLT, 2D Pickup, 3.9 X, 4WD, StandardSECTION Idle Pressure Test
  1. 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). Connect pressure hose from valve side of steering gear to valve side of gauge. Valve must be installed on outlet side of gauge. See Fig 1.
  2. Fully open shutoff valve on test gauge. With a thermometer in fluid reservoir, start engine and warm fluid to 150-170Β°F (66-77Β°C). Turning wheels from stop-to-stop will aid in warming fluid. DO NOT hold wheels against stop.
  3. With engine at idle and gauge valve open, check initial pressure. See POWER STEERING PUMP PRESSURE TEST SPECIFICATIONSΒ  table. If pressure is greater than 125 psi (8.8 kg/cm2 ), check for restricted hoses or crimped lines.
