REMOVAL
1. DISCHARGE REFRIGERANT FROM REFRIGERA TION
SYSTEM
HINT:
At the time of installation, refer to the following procedure.
Evacuate air from refrigeration system.
Charge system with refrigerant and inspect for leakage of
refrigerant.
Specified amount:
850 ± 50 g (29.98 ± 1.76 oz.)

(b) Center brace
3. DISCONNECT DISCHARGE HOSE AND LIQUID TUBE
Torque: 10 N·m (100 kgf·cm, 7 ft·lbf)
NOTICE:
Cap the open fittings immediately to keep moisture or dirt
out of the system.
HINT:
At the time of installation, lubricate 2 new O −rings with com-
pressor oil to compressor.
4. REMOVE CONDENSER
(a) Remove 2 condenser mounting bolts.
(b) Pull out the condenser between the radiator and the body.

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.

COOLING RADIATOR
1996 LAND CRUISER (RM451U)
ON−VEHICLE INSPECTION
1. REMOVE RADIATOR TANK CAP
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
2. INSPECT RADIATOR CAP
NOTICE:
If the radiator cap has contaminations, always rinse it with
water. Before using a radiator cap tester, wet the relief
valve and pressure valve with coolant or water.
Using a radiator cap tester, pump the tester and measure the
relief valve opening pressure. Standard opening pressure:
74 − 103 kPa
(0.75 − 1.05 kgf/cm
2, 10.7 − 14.9 psi)
Minimum opening pressure:
59 kPa (0.6 kgf/cm
2, 8.5 psi)
HINT:
Use the tester’s maximum reading as the opening pressure.
If the opening pressure is less than minimum, replace the radia-
tor cap.
3. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump
for leaks. If no external leaks are found, check the heater core,
cylinder block and head.
4. REINSTALL RADIATOR CAP
