Minimum fluid pressure: 10,000 kPa (102 kgf/cm 2 , 1,451 psi) NOTICE: Do not keep the valve closed for more than 10 seconds. Do not let the fluid temperature become too high. (h) With the engine idling, open the valve fully. (i) Measure the fluid pressure at engine speeds of 1,000 rpm and 3,000 rpm. Standard difference fluid pressure: 490 kPa (5 kgf/cm 2 , 71 psi) or less NOTICE: Do not turn the steering wheel. (j) With the engine idling and valve fully opened, turn the steering wheel to full lock. Minimum fluid pressure: 10,000 kPa (102 kgf/cm 2 , 1,451 psi) NOTICE:
Do not maintain lock position for more than 10 seconds. Do not let the fluid temperature become too high. (k) Disconnect the SST. SST: 09640-10010 09641-01010 09641-01030 09641-01060 (l) Connect the pressure feed tube . (m) Install the air cleaner assembly with air cleaner hose . (n) Bleed air from the power steering system. 5. CHECK IDLE-UP (a) Turn the air conditioning switch off. (1) Start the engine and run it at idle. (2) Fully turn the steering wheel. (3) Check that the engine rotations decrease when the vacuum hose of the air control valve is pinched. (4) Check that the engine rotations increase when the hose is released.
