ON±VEHICLE INSPECTION
STEERING WHEEL FREEPLAY CHECK
With the vehicle stopped and tires pointed straight ahead,
rock the steering wheel gently back and forth with light finger
pressure.
Freeplay should not exceed the maximum.
 

 
 Freeplay mm(in.) 
Maximum30 (1 18) Maximum30 (1.18)
IDLE±UP CHECK
1. TURN AIR CONDITIONING SWITCH OFF
2. CHECK IDLE±UP
(a) Start engine and run it at idle.
(b) Fully turn the steering wheel.
(c) Check that the engine speed decreases when the air control
valve hose is pinched.
(d) Check that the engine speed increases when the hose is
released.
FLUID LEVEL CHECK
1. KEEP VEHICLE LEVEL
2. CHECK FLUID LEVEL
Check the fluid level in the reservoir.
If necessary, add fluid.
Fluid:
ATF DEXRON[ II
HINT: Check that the fluid level is within the HOT LEVEL
range on the dipstick of the reservoir cap. If the fluid is cold,
check that it is within the COLD LEVEL range.
3. BOOST FLUID TEMPERATURE
(a) Start the engine and run it at idle.
(b) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature:
805C (1765F)
± STEERINGON±VEHICLE INSPECTIONSR±7

4. CHECK FOR FOAMING OR EMULSIFICATION
If there is foaming or emulsification, bleed power steering
system.
(See page SR±9)
5. CHECK FLUID LEVEL RISE
(a) With the engine idling, measure the fluid level in the reservoir.
(b) Stop the engine.
(c) Wait a few minutes and remeasure the fluid level in the
reservoir.

REPLACEMENT
1. JACK UP FRONT OF VEHICLE AND SUPPORT IT WITH
STANDS
2. DRAIN FLUID
(a) Disconnect the return hose from the PS vane pump.
(b) Turn the steering wheel from lock to lock.
3. FILL OIL RESERVOIR
(a) Fill oil reservoir with fresh fluid.
Fluid:
ATF DEXRON[ II
(b) Start engine.
(c) After 1 or 2 seconds, fluid will begin to discharge from the
return hose.
(d) Stop the engine immediately.
NOTICE: Take care that some fluid remains in the oil res-
ervoir.
(e) Repeat steps (a), (b), (c) and (d) until there is no more air in
fluid.
(f) Connect the return hose.
4. BLEED POWER STEERING SYSTEM

POWER STEERING SYSTEM BLEEDING
1. JACK UP FRONT OF VEHICLE AND SUPPORT IT WITH
STANDS
2. TURN STEERING WHEEL
With the engine stopped, turn the steering slowly from lock
to lock several times.
NOTICE: Take care that some fluid remains in the oil res-
ervoir.
3. LOWER VEHICLE
4. START ENGINE
Run the engine at idle for a few minutes.
5. TURN STEERING WHEEL
(a) With the engine at idling, turn the wheel to left or right full lock
and keep it there for 2±3 seconds, then turn the wheel to the
opposite full lock and keep it there for 2±3 seconds.
(b) Repeat (a) several times.
6. STOP ENGINE
7. CHECK FOR FOAMING OR EMULSIFICATION
If the system has to be bled twice specifically because of
foaming or emulsification, check for fluid leaks in the system.
8. CHECK FLUID LEVEL
