3B1-6 POWER STEERING except Above Models: 10,297 kPa (105 kg/cm 2 / 1,493 psi) HBB: Hydraulic Booster Brake 6. After air release has been completed, check the fluid level in the tank and also confirm that the joints have no fluid leak. If the pressure recorded is within specified range, the steering system is functioning within its specifi- cations. If the pressure recorded is lower than specified range, steering unit is leaking internally and must be disassembled and repaired. Power Steering System Bleeding 1. Raise the front wheels with a jack. (It is recom- mended that a turn-table should be placed under right hand and left hand side front wheels at this time.) 2.
Replenish the fluid tank with ATF Dexron ® -III, and repeat the full steering (turning to the extreme ends of the steering) in both right hand side and left hand side directions quietly with the engine stopped. Caution: Under this condition, the air trapped in the fluid piping will be released from the fluid tank to the atmosphere in the form of large air bubbles. 3. Whenever the fluid level in tank is lowered, replen- ish the tank with ATF Dexron ® -III in the amount equivalent to the consumption. Caution: Pay extra care over the fluid level so that fluid will not run out. 4. Start the engine and repeat the full steering several times quietly with the engine kept idling. Caution:
The time needed for full steering should be less than five minutes. (Prolonged full steering of more than five sec- onds will cause the fluid temperature to raise significant- ly.) 5. Lower the front wheels and turn the steering wheel in both left hand and right hand sides several times with the engine run. If no abnormal noise can be heard at this time, air might be completely re- leased. Caution: If the abnormal noise (creaky, “zi-zi” sound etc.) can be heard in the piping after the step No. 5 has been com- pleted, the air is still trapped in the piping and air release has not been completed.
In this case, continue repetition of steering wheel turn in the both directions of left hand and right hand sides until the fluid temperature is increased up to around 50 — 80 ° C (122 — 176 ° F). When the temperature reaches this degree, stop the engine and leave the engine for about five minutes. (Within five minutes, air bubbles can be collected.) Start the engine again and repeat the full steering several times.
