DRIVE BELT
INSPECTION
1. CHECK DRIVE BELT TENSION
Using a belt tension gauge, measure the belt tension.
Belt tension gauge:
DENSO BTG-20 (95506-00020) or
Borroughs No. BT-33-73F
Drive belt tension:
New belt: 140 - 180 lbf
Used belt: 80 - 120 lbf
NOTICE:
After installing the belt, check that it fits properly in the
ribbed grooves.
HINT:

ºNew beltº refers to a belt which has been used less than
5 minutes on a running engine.

ºUsed beltº refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
2. VEHICLES WITH BELT TENSION ADJUSTING BOLT:
ADJUST DRIVE BELT TENSION
(a) Loosen the bolts A and B.
(b) Loosen the lock nuts D and E.
(c) Adjust adjusting bolt F so that its protrusion above nut C
is ± 0 mm (0 in.).
(d) Fix nut C using lock nut D.
(e) Push up the PS pump body so that there is no free play
in the belt. Turn adjusting bolt F to obtain the play in the
correct belt tension as specified above.
NOTICE:
Ensure that the pump body and nut C are positioned cor-
rectly, as shown before turning bolt F to adjust the bet ten-
sion.
(f) Torque the bolt A.
Torque: 43 N´m (440 kgf´cm, 32 ft´lbf)

(g) Torque the bolt B.
Torque: 43 N´m (440 kgf´cm, 32 ft´lbf)
(h) Loosen adjusting bolt F by 4 or 5 turns.
NOTICE:
Check that there is a gap of 5 mm (0.20 in.) or more between
the tip of nut C and the pump body.
(i) Fix adjusting bolt F with lock nut E.
(j) Recheck the belt tension.

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 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.
(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-6)

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 cap dipstick. 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-5)
(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-5)
(i) Check the fluid level.

2. CHECK STEERING FLUID PRESSURE
(a) Disconnect the pressure feed tube from the PS vane
pump. (See page SR-24)
(b) Connect SST, as shown in the illustration below.
SST 09640-10010 (09641-01010, 09641-01030,
09641-01060)
NOTICE:
Check that the valve of the SST is in the open position.
(c) Bleed the power steering system.
(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:
6,374 kPa (65 kgf/cm
2, 925 psi)
NOTICE:

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

Do not let the fluid temperature become too high.
