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

Author: Date:
1996 LAND CRUISER (RM451U)
UNDER HOOD
GENERAL MAINTENANCE
1. GENERAL NOTICE
Maintenance items may vary from country to country. Check the owner’s manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performe\
d.
Periodic maintenance service must be performed according to whichever interval in\
the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time inter\
val (months).
Maintenance service after the last period should be performed at the same interval \
as before unless
otherwise noted.
Failure to do even one item can cause the engine to run poorly and incre\
ase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL Check that the coolant level is between the FULL and LOW lines on the se\
e −through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leave\
s, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upp\
er and lower level lines on the case.
If level is low, add distilled water only.
6. BRAKE FLUID LEVELS
Check that the brake fluid level is near the upper level line on the see\
−through reservoir.
7. ENGINE DRIVE BELTS
Check drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL
(a) Check the level on the dipstick.
(b) The level should be in the HOT or COLD range depending on the fluid temp\
erature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking and foot brake applied, shift the sel\
ector into all positions from the P to L, and then shift into the P.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re −insert the dipstick fully and check that
the fluid level is in the HOT range.
(d) Do this check with the fluid at normal driving temperature (70 − 80°C (158 − 176° F)).
HINT:
Wait about 30 minutes before checking the fluid level after extended driving\
at high speeds in hot weather,
driving in heavy traffic or with a trailer.
11. EXHAUST SYSTEM
Visually inspect for cracks, holes or loose supports.
If any change in the sound of the exhaust or smell of the exhaust fumes is\
noticed, have the cause located
and corrected.
