# Power steering gear housing test pressure (2001–2003 NB2, non-turbo)

Canonical URL: https://miatatorque.com/spec/power-steering-gear-housing-test-pressure-nb2/

Applicability: NB 2001–2003 (BP-Z3) — Actual 2003 factory specification corroborated by early NB2 publication 1719-1U-01G. 2001–2002 inferred, not factory-year verified. Actual 2004–2005 higher-pressure specifications are separate.

Confidence: fsm

7,846—8,335 kPa {80—85 kgf/cm², 1,138—1,208 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 and bleed air; warm fluid to 50—60°C {122—140°F}. Open the gauge valve fully; at 1,000—1,500 rpm turn fully left and right and measure pressure. Do not hold the steering fully turned for more than 5 seconds; excessive fluid heat damages the pump. Repair or replace the gear housing if out of specification; follow the complete factory gauge removal and bleeding procedure. The early NB2 factory publication corroborates this lower range. Do not substitute the higher actual 2004–2005 range."
