1.Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.
Standard value:
When belt tension is inspectedor readjusted
When new belt is installed
/ 9 - 11 mm (.35 - .43 in.)
I
’ 7 - 8.5 mm (.28 - .33 in.)
2.If the deflection is out of the standard values, adjust the belt
tension using the following procedure.
(1) Loosen the tension pulley’s securing bolts A and
B.(2) Mount the extension bar on the tension pulley.
(3) While increasing the tension of the V-belt with the
extension bar, retighten the tension pulley’s securing
bolts A and B in the order mentioned.
FLUID LEVEL CHECKM37FlAJ
1.Park the vehicle on a flat, level surface, start the engine, and
then turn the steering wheel several times to raise the
temperature of the fluid to approximately 50
- 60°C (122 -
140°F).
2.With the engine running, turn the wheel all the way to the
left and right several times.
3.Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTM37FJAL1. Raise the front wheels on a jack, and then support them
with rigid racks.
2. Disconnect the return hose connection.
3. Connect a vinyl hose to the return hose, and drain the oil
into a container.
4. Disconnect the high-tension cable, and then while operat-
ing the starting motor intermittently, turn the steering
wheel all the way to the left and right several times to drain
all of the fluid.
Caution
Be careful not to position the high-tension cable nearthe carburetor or the delivery pipe.
5.Connect the return hoses securely, and then secure it with
the clip.
6.Fill the oil reservoir with the specified fluid up to the lower
position of the filter, and then bleed the air.

(1) When installing the steering lock cylinder and steering
lock bracket to the column tube, temporarily install the
steering lock in alignment with the column boss.
(2) After checking that the lock works properly, tighten the
special bolts until the head twists off.
CautionThe steering lock bracket and bolts must be re-
placed with new ones when the steering lock
cylinder is installed.3. INSTALLATION OF BEARING
(1) Fill the inside of the bearing with multipurpose grease.
(2) Install the bearings to the shaft on the joint assembly.
(3) Wrap vinyl tape approximately one and one-half times

Secure the power cylinder on the tie rod side with a
spanner and remove the power cylinder mounting nut.
INSPECTIONM37SCM
TIR ROD SWING TORQUE INSPECTION
(1) Swing the tie rod ten times hard.
(2) Point the tie rod end down, then attach a spring balance as
shown in the illustration to measure swing resistance
(swing torque).
Standard value: 9

[0.5 - 3 Nm (4 - 26 in.lbs.)l(3) If the swing resistance exceeds the standard value, replace
the tie rod.
(4) If the swing resistance is less than the standard value, the
ball joint may be reused as long as it is not loose and
operates smoothly.
POWER CYLINDER SLIDE RESISTANCE CHECK
(1) Place the piston in a neutral position.
(2) Wrap a wire around the tie rod end, then measure slide
resistance with a spring balance as shown in the illustration.
Standard value: 67 N (15
Ibs.) or less
(3) If the slide resistance exceeds the standard value,
replace,the power cylinder.
(4) If the slide resistance is less than the standard value, the

HEATERS AND MANUAL AIR CbNDlTlONER -Service Adjustment Procedures 55 17
ADJUSTMENT PROCEDURES(1) Select a quiet area for testing. Duplicate conditions as much
as possible. Switch compressor on and off several times to
clearly identify compressor noise.
To duplicate high ambient conditions (high head pressure),
restrict air flow through condenser. Install manifold gauge
set to make sure discharge pressure doesn’t exceed 2,070
kPa (300 psi).
(2) Tighten all compressor mounting bolts, clutch mounting
bolt, and compressor drive belt. Check to assure clutch coil
is tight (no rotation or wobble).
(3) Check refrigerant hoses for rubbing or interference that can
cause unusual noises.
(4) Check refrigerant charge. (See “Charging System”.)
(5) Recheck compressor noise as in Step 1.
(6) If noise still exists, loosen compressor mounting bolts and
retorque. Repeat Step 1.
(7) If noise continues, replace compressor and repeat Step 1.
POWER RELAY CHECKMBBFNAK(1) Remove the radiator fan motor relays (HI) and (LO) from the
relay box on the right of the engine compartment.
(2) Remove the radiator fan motor relay (air conditioner),
condenser fan motor relays (HI) and (LO), and
air-conditioner compressor relay from the relay box on the left
of the engine compartment.
(3) Remove the blower motor relay from the junction box.
(4) Remove the blower motor HI relay from the blower case
assembly.
(5) Check the continuity between terminals using a circuit
tester.

IDLE-UP OPERATION CHECKM55FOAB
(1) Before inspection and adjustment set vehicle in the
following condition:
lEngine coolant temperature: 80 - 95°C (176 - 203°F)
lLights, electric cooling fan and accessories: Set to OFF
l Transaxle: Neutral (N or P for vehicles with
A/T)l Steering wheel: Straightforward
(2) Check to be sure that the idling speed becomes the
standard value when the air conditioner switch is switched
ON and the air conditioner is activated.
Standard value: 900
+ 100 rpm
NOTEThere is no necessity to make an adjustment, because the
idling speed is automatically adjusted by the ISC” system.
If, however, there occurs a deviation from the standard
value for some reason, check the ISC” system.
