SCAN TOOL (See page SF−1)
3. INSPECT FUEL CUT−OFF PRM
(a) Increase the engine speed to at least 2,500 rpm.
(b) Use a sound scope to check for injector operating noise.
(c) Check that when the throttle lever is released, injector op-
eration noise stops momentarily and then resumes.

DRIVE BELT
INSPECTION
INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
If any defect has been found, replace the drive belt.
HINT:
Cracks on the rib side of a belt are considered acceptable. If the
belt has chunks missing from the ribs, it should be replaced.
(b) Using a belt tension gauge, measure the belt tension.
Belt tension gauge:
DENSO BTG−20 (95506−00020)
Borroughs No. BT−33−73F
Drive belt tension:
New belt: 95 − 145 lbf
Used belt: 60 − 100 lbf
If the belt tension is not as specified, adjust it.
HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing a belt, check that it fits properly in the
ribbed grooves.
Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.
After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.

1. CHECK FLUID LEVEL (See page SR−5)
2. JACK UP FRONT OF VEHICLE AND SUPPORT IT
WITH STANDS
3. TURN STEERING WHEEL
With the engine stopped, turn the wheel slowly from lock to lock
several times.
4. LOWER VEHICLE
5. START ENGINE
Run the engine at idle for a few minutes.
6. TURN STEERING WHEEL
(a) With the engine 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 se-
conds.
(b) Repeat (a) several times.
7. STOP ENGINE
8. 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.
9. CHECK FLUID LEVEL (See page SR−5)

INSPECTION
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
system (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.

STEERING WHEEL
INSPECTION
1. CHECK STEERING WHEEL FREEPLAY
With the vehicle stopped and tires facing straight ahead, rock
the steering wheel gently back and forth with light finger pres-
sure.
Freeplay should not exceed the maximum.
Maximum freeplay: 30 mm (1.18 in.)
2. CHECK STEERING EFFORT
(a) Center the steering wheel.
(b) Remove the steering wheel pad (See page SR−12).
(c) Start the engine and run it at idle.
(d) Measure the steering effort in both directions.
Reference: 5.9 N·m (60 kgf·cm, 52 in.·lbf)
HINT:
Be sure to consider the tire type, pressure and contact surface
before making your diagnosis.
(e) Torque the steering wheel set nut.
Torque: 34 N·m (350 kgf·cm, 25 ft·lbf)
