2. CHECK STEERING FLUID PRESSURE
(a) Remove the air cleaner assembly with the air cleaner
hose connected (See page SR±26).
(b) Disconnect the pressure feed tube from the PS vane
pump (See page SR±26).
(c) Connect SST, as shown in the illustration.
SST 09640±10010 (09641±01010, 09641±01030,
09641±01060)
NOTICE:
Check that the valve of the SST is in the open position.
(d) Bleed the power steering system (See page SR±4).
(e) Start the engine and run at idle.
(f) Turn the steering wheel from the lock position to the other
side of lock position several times to boost fluid tempera-
ture.
Fluid temperature: 80 °C (176 °F)
(g) With the engine idling, close the valve of the SST and ob-
serve the reading on the SST.
Minimum fluid pressure:
8,336 kPa (85 kgf/cm
2, 1,209 psi)
NOTICE:

Do not keep the valve closed for more than 10 se-
conds.

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.
Difference in fluid pressure:
490 kPa (5 kgf/cm
2, 71 psi) or less
NOTICE:
Do not turn the steering wheel.
