Canonical URL: https://miatatorque.com/spec/power-steering-pump-test-pressure-nb2-2004-2005/

Applicability: NB 2004–2005 (BP-Z3) — Actual2004 and2005 factory evidence.; NB 2004–2005 (BP-Z3-TURBO) — 2005 factory evidence; 2004 inferred within MSM family.

Confidence: fsm

8.33–9.06 MPa {85.0–92.3 kgf/cm², 1,209–1,314 psi}

Always confirm against your factory manual. Match every restriction and follow all stages and procedure notes. Disputed claims must not be automatically resolved. The complete record below preserves every printed unit, source claim and procedure.

    "notes": "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."
