Pump Fluid Pressure Test
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Mazda Tribute, 2002 Mazda Millenia, 2002 Mazda 626, 2001 Mazda Tribute, and 2001 Mazda Protege. However, it is still accessible from the selected car via links, so may be relevant.
- Disconnect pressure line from steering pump. Connect pressure gauge/valve between steering pump and steering gear. See Fig 1. Bleed air from system.
- Completely open valve. Start engine and operate at idle. Turn steering wheel from lock to lock to increase fluid temperature to 122-140°F (50-60°C). To measure pump fluid pressure, close gauge valve completely.
- Increase engine speed to 1000-1500 RPM. Measure oil pump fluid pressure. Ensure pump pressure is within specification. See HYDRAULIC SYSTEM FLUID PRESSURE SPECIFICATIONS table. If pressure is not within specification, replace pump.
CAUTION:
Do not leave gauge valve closed for more than 15 seconds, or pump may be damaged.
