1. 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:
Check that the fluid level is within the HOT LEVEL range on the
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 power steering sys-
tem (See page SR-4).
(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 (See page
SR-4).
(i) Check the fluid level.

2. CHECK STEERING FLUID PRESSURE
(a) Disconnect the pressure feed tube (See page SR-27).
(b) Connect SST to pressure feed tubes, as shown in the il-
lustration below.

09641-01060)
NOTICE:
Check that the valve of the SST is in the open position.
(c) Bleed the power steering system (See page SR-4).
(d) Start the engine and run it at idle.
(e) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80 °C (176 °F)
(f) With the engine idling, close the valve of the SST and ob-
serve the reading on the SST.
Minimum fluid pressure:
7,845 kPa (80 kgf/cm
2, 1,138 psi)
NOTICE:

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

Do not let the fluid temperature become too high.
