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 left or right
full lock position and keep it there for 2 - 3 seconds,
then turn the wheel to the opposite full lock position
and keep it there for 2 - 3 seconds.
(2) Repeat (1) several times.
(g) Stop the engine.
(h) Check for forming or emulsification.
Especially, if the system has to be bled twice because of foam-
ing or emulsification, check for fluid leaks in the system.
(i) Check 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:
Check that the fluid level is within the HOT LEVEL range on the
reservoir cap. If the fluid is cold, check that it is within the COLD
LEVEL range.
