(c) Ground terminal on the wire harness side through a 3.4
W test bulb.
(d) Turn the ignition switch ON, and check that the bulb lights
up and that the receiver gauge needle moves to the high
side.
If operation is not as specified, measure the receiver gauge re-
sistance.
14. INSPECT OIL PRESSURE RECEIVER GAUGE RESIS- TANCE
Measure the receiver gauge resistance between terminals. Resistance:

If resistance value is not as specified, replace the receiver
gauge.
15. INSPECT OIL PRESSURE SENDER GAUGE OPERA-
TION
(a) Disconnect the connector from the sender gauge.
(b) Apply battery positive voltage to the sender gauge termi- nal through a test LED.
(c) Check that the bulb does not light when the engine is stopped.
(d) Check that the LED flashes when the engine is running. The number of flashed should vary with engine speed.

Remove the 2 bolts and support from the hood.
HINT:
While supporting the hood with your hand, remove the hood.
2. REMOVE DAMPER STAY FROM BODY
Remove the 2 bolts and support.
3. REPLACE DAMPER STAY
NOTICE:
Do not disassemble the damper stay because the cyl-
inder is filled with pressurized gas.
If the damper stay is to be replaced, drill a 2.0 − 3.0 mm
(0.079 − 0.118 in.) hole as shown in the illustration to
completely release the high− pressure gas before dis-
posing of it.
When drilling, chips may fly out so work carefully.
The gas is colorless, odorless and non −toxic.
When working, handle the damper stay carefully.
Never score or scratch the exposed part of the piston
rod, and never allow paint or oil to get on it.
Do not turn the piston rod and cylinder with the damp-
er stay fully extended.
4. INSTALL DAMPER STAY

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.

1996 LAND CRUISER (RM451U)
8. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation ATF temperature 50 − 80°C (122 − 176° F).
The line pressure test should always be carried out in pairs. One techni\
cian should observe
the conditions of wheels or wheel stoppers outside the vehicle while the ot\
her is doing the test.
Be careful to prevent SST’s hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the transmission case right side and connect SST\
(See page AT−18
for the location to connect SST).
SST 09992 −00094 (09992 −00150, 09992−00270)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressed firmly on the brake pedal and shift into D p\
osition.
(6) Measure the line pressure when the engine is idling.
(7) Press the accelerator pedal all the way down. Quickly read the highest line pr\
essure when engine
speed reaches stall speed.
NOTICE:
Release the accelerator pedal and stop test if the rear wheels begin to rotate before the engine speed
reaches the specified stall speed.
(8) In the same manner, do the test in R position.
Specified line pressure:
Condition D position kPa (kgf/cm2, psi) R position kPa (kgf/cm2, psi)

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT DISTRIBUTOR CONNECTOR
3. REMOVE SPARK PLUGS (See page IG−1 )
4. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible. Compression pressure:
1,176 kPa (12.0 kgf/cm
2, 171 psi) or more
Minimum pressure: 883 kPa (9.0 kgf/cm
2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
If the cylinder compression in one or more cylinders is low, pour
a small amount of engine oil into the cylinder through the spark
plug hole and repeat steps (a) through (c) for cylinders with low
compression.
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG−1 )
6. RECONNECT DISTRIBUTOR CONNECTOR
