DRIVE BELT
INSPECTION
1. INSPECT DRIVE BELT
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
missing chunks from the ribs are found on the belt, it should be
replaced.
2. CHECK DRIVE BELT TENSION
Measure the drive belt deflection.
Drive belt tension: at 98 N (10 kgf, 22 lbf)
4A–FE and 7A–FE engines:
New belt5 – 6 mm (0.20 – 0.24 in.)
Used belt6 – 8 mm (0.24 – 0.31 in.)
3S–FE engine:
New belt8 – 10 mm (0.31 – 0.39 in.)
Used belt10 – 13 mm (0.39 – 0.51 in.)
2C–T, 2C–TE and 1CD–FTV engines:
New belt11 – 14 mm (0.43 – 0.55 in.)
Used belt15 – 18 mm (0.59 – 0.71 in.)

– STEERINGDRIVE BELT
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.
(Reference)

Using a belt tension gauge, measure the drive belt ten-
sion.
Drive belt tension:
4A–FE, 7A–FE and 3S–FE engines:
New belt441 – 539 N (45 – 55 kgf)
Used belt245 – 392 N (25 – 40 kgf)
2C–T, 2C–TE and 1CD–FTV engines:
New belt539 – 637 N (55 – 65 kgf)
Used belt245 – 392 N (25 – 40 kgf)
If the belt tension is not as specified, adjust it.

POWER STEERING FLUID
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 / 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 Pub. No. RM599E on 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 Pub.
No. RM599E on 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 Pub. No. RM599E on page SR–21 (4A–FE
and 7A–FE engines), SR–24 (3S–FE engine) and see
page SR–8 (2C–T, 2C–TE and 1CD–FTV engines)].
(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 (See Pub. No. RM599E
on page SR–5).
(d) Start the engine and run it at idle.
(e) Turn the steering wheel from lock to lock several times to
boost fluid temperature.

(f) With the engine idling, close the valve of the SST and ob-
serve the reading on the SST.
Minimum fluid pressure:

NOTICE:

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

Do not let the fluid temperature become too high.
(g) With the engine idling, open the valve fully.
(h) Measure the fluid pressure at engine speeds of 1,000 rpm
and 3,000 rpm.
Difference fluid pressure:
490 kPa (5 kgf/cm
2, 71 psi) or less
NOTICE:
Do not turn the steering wheel.
(i) With the engine idling and valve fully opened, turn the
steering wheel to full lock.

NOTICE:

Do not maintain lock position for more than 10 se-
conds.

Do not let the fluid temperature become too high.
(j) Disconnect the SST.
(k) Connect the pressure feed tube to PS vane pump
[See Pub. No. RM599E on page SR–22 (4A–FE and 7A–
FE engines), SR–25 (3S–FE engine), and see page
