Power steering pump test pressure (2001–2003 NB2, non-turbo)

7,846—8,208 psi (335 kPa; 80—85 kgf/cm², 1,138—1)7,846—8,335 kPa {80—85 kgf/cm², 1,138—1,208 psi}

Factory manualTaken from a Mazda factory workshop manual, with page citation.
Procedure

Connect factory pressure-gauge SSTs at the pump pressure pipe and bleed air. With gauge valve fully open, warm fluid to 50—60°C {122—140°F}. Fully close the valve and measure pump pressure at 1,000—1,500 rpm. Do not leave the valve closed for more than 5 seconds; excessive fluid heat damages the pump. Follow the complete factory procedure to disconnect the gauge, restore the pipe and bleed air. The early NB2 factory publication corroborates this lower range. Do not substitute the higher actual 2004–2005 range.
