(b) Turn the selector switch of the actuator checker to
”FRONT RH” position.
(c) Push and hold in the SUB MOTOR switch for a few se- conds.
(d) Depress the brake pedal and hold it until the step (g) is
completed.
(e) Push the POWER switch, and check that the brake pedal
does not go down.
NOTICE:
Do not keep the POWER switch pushed down for more than
10 seconds.
(f) Release the switch, and check that the pedal goes down.
(g) Push and hold in the SUB MOTOR switch for a few se- conds, and check that the pedal returns.
(h) Release the brake pedal.
(i) Push and hold in the SUB MOTOR switch for a few se- conds.
(j) Depress the brake pedal and hold it for about 15 seconds.

switch for a few seconds. Check that the brake pedal
does not pulsate.
(k) Release the brake pedal.
5. INSPECT FOR OTHER WHEELS

3. INSPECT DRIVE BELTS
(a) Visually check the drive belt for cracks, oiliness or wear.
Check that the belt does not touch the bottom of the pulley
groove.
If necessary, replace the drive belts as a set.
(b) Using a belt tension gauge, measure the belt tension. Belt tension gauge:
Nippondenso BTG−20 (95506 −00020)
Borroughts No. BT−33−73F
Drive belt tension:
New belt400 − 580 N (41.0 − 59.1 kgf, 90.4 − 130.2 lbf)
Used belt200 − 390 N (20.4 − 40.0 kgf, 45.0 − 88.2 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 new belt, run the engine for about 5 min-
utes and recheck the belt tension.
4. VISUALLY CHECK GENERATOR WIRING AND LIS- TEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
5. INSPECT DISCHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ”ON”. Check that the discharge warning light comes on.
(b) Start the engine. Check that the light goes off.

If the light does not operate as specified, troubleshoot the dis-
charge warning light circuit.
6. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per the manufacturer’s instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:
Disconnect the wire from terminal B of the generator
and connect it to the negative ( −) lead of the amme-
ter.
Connect the positive (+) lead of the ammeter to ter-
minal B of the generator.
Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
Ground the negative ( −) lead of the voltmeter.
(b) Check the charging circuit as follows:
With the engine running from idle to 2,000 rpm, check the
reading on the ammeter and voltmeter.
Standard amperage 10 A or less
Standard voltage:
at 25° C ’(77°F)14.0 − 15.0 V
at 115°C ’(239° F)13.5 − 14.3 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than the standard voltage, check
the voltage regulator and generator as follows:
With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.
If the voltmeter reading is more than standard volt-
age, replace the voltage regulator.
If the voltmeter reading is less than standard volt-
age, check the generator.
7. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
”HI”.

COOLANT
INSPECTION
HINT:
Check the coolant level when the engine is cold.
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ”LOW” and ”FULL”\
lines.
If low, check for leaks and add engine coolant up to the ”FULL” line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot, as fluid and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or scale around the r\
adiator cap or radiator filler
hole, and the coolant should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.

COOLING COOLANT
1996 LAND CRUISER (RM451U)
REPLACEMENT
REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
See step 2. (a) above.
(b) Drain the coolant from the radiator drain cock and engine drain plug (Engine drain plug at the left of engine block.).
(c) Close the drain plugs. Torque:Torque (Engine drain plug):
29 N·m (300 kgf·cm, 22 ft·lbf)
(d) Slowly fill the system with coolant.
Use a good brand of ethylene −glycol base coolant
and mix it according to the manufacturer’s direc-
tions.
Using coolant which includes more than 50 % ethyl-
ene−glycol (but not more than 70 %) is recom-
mended.
NOTICE:
Do not use an alcohol type coolant.The coolant should be
mixed with demineralized water or distilled water. Capacity:
w/ Front heater:
13.7 liters (14.4 US qts, 12.1 lmp. qts)
w/ Front and rear heaters:
14.7 liters (15.5 US qts, 12.9 lmp. qts)
(e) Reinstall the radiator cap.
(f) Warm up the engine and check for leaks.
(g) Recheck the coolant level and refill as necessary.
