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.
