Hydraulic System Pressure Test
- Install Pressure Gauge (US1074 B ) between pressure hose and pressure line at valve housing. Open pressure gauge valve. Run engine at idle. Turn steering wheel from lock to lock several times.
- On Vanagon, pressure should be 1670-1750 psi (117-123 kg/cm2 ). On all others, pressure should be 1100-1200 psi (78-84 kg/cm2 ). If pressure is not within limits, see PUMP PRESSURE TEST .
- If pump pressure is within specification, but system pressure is low, replace steering gear.
