Steering wheel feels heavy.
Fix: If air remains in fluid, steering wheel may feel heavy.
Relief pressure higher or lower than 7000 — 8000 kPa (70 - 80 kg/cm², 995 - 1138 psi).
Fix: When it is higher than specified values, possible cause is malfunction of relief valve. When it is lower than specified values, possible cause is either failure of P/S pump or settling of relief valve spring.
Line pressure lower than 1000 kPa (10 kg/cm², 142 psi).
Fix: Check line pressure by measuring hydraulic pressure with engine idling and hands off steering wheel. When line pressure is higher than specified values, check control valve and piping for clogging.
Leakage from gear box, P/S pump or oil tank.
Fix: Start engine and turn steering wheel fully to the right and left so that maximum hydraulic pressure is provided. Then visually check gear box, P/S pump and oil tank themselves and each joint of their connecting pipes for leakage.
Humming noise from P/S pump.
Fix: If air remains in fluid, P/S pump may make humming noise.
Belt tension not within 6 — 7 mm (0.24 — 0.28 in.)
Fix: Loosen adjuster bolt, and adjust belt deflection by sliding adjuster.
Belt is free from any damage and properly fitted in pulley groove.
Fix: Check that belt is free from any damage and properly fitted in pulley groove.
