ON±VEHICLE INSPECTION
1. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords,
etc.
If any defect is found, replace the drive belt.
HINT:
Cracks on the rib side of a belt are considered acceptable. If the
missing chunks from the ribs are found on the belt, it should be
replaced.
2. BLEED POWER STEERING SYSTEM
(a) Check the fluid level.
(b) Jack up the front of the vehicle and support it with the
stands.
(c) Turn the steering wheel.
(1) With the engine stopped, turn the wheel slowly from
lock to lock several times.
(d) Lower the vehicle.
(e) Start the engine.
(1) Run the engine at idle for a few minutes.
(f) Turn the steering wheel.
(1) With the engine idling, turn the wheel to right full lock
position and keep it there for 2 to 3 seconds, then
turn the wheel to left full lock position and keep it
there for 2 to 3 seconds.
(2) Repeat (1) several times.
(g) Stop the engine.
(h) Check for foaming or emulsification.
If the system has to be bled twice specifically because of foam-
ing or emulsification, check for fluid leaks in the system.
(i) Recheck the fluid level.
3. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the oil
reservoir.
If necessary, add fluid.
Fluid: ATF DEXRON II or III
HINT:
If the fluidis hot, check that the fluid level is within the HOT LEV-
EL range on the oil reservoir. If the fluid is cold, check that it is
within the COLD LEVEL range.

(c) Start the engine and run it at idle.
(d) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80 C (176 F)
(e) Check for foaming or emulsification.
If there is foaming or emulsification, bleed the power steering
system.
(f) With the engine idling, measure the fluid level in the oil reservoir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the oil reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed power steering system.
(i) Check the fluid level.
4. CHECK STEERING FLUID PRESSURE
(a) AZ Series: Disconnect the pressure feed tube assy from the vane
pump assy (See page 51±9).
(b) 1CD±FTV: Disconnect the pressure feed tube assy from the vane
pump assy (See page 51±19).
(c) AZ Series: Connect SST(s), as shown in the illustration on the next
page.
SST 09640±10010 (09641±01010, 09641±01030, 09641±01060)
NOTICE:
Check that the valve of SST(s) is in the open position.
(d) 1CD±FTV: Connect SST(s), as shown in the illustration on the next
page.
SST 09640±10010 (09641±01010, 09641±01020, 09641±01030)
NOTICE:
Check that the valve of SST(s) is in the open position.
(e) Bleed the power steering system.
(f) Start the engine and run it at idle.
(g) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80 C (176 F)

(h) With the engine idling, close the valve of SST(s) and ob-
serve the reading on SST(s).

NOTICE:
Do not keep the valve closed for more than 10 se-
conds.
Do not let the fluid temperature become too high.
(i) With the engine idling, open the valve fully.
(j) Measure the fluid pressure at engine speeds of 1,000 rpm
and 3,000 rpm.
Fluid pressure difference:
