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 ºLOWº and ºFULLº lines at normal temperature
(20°C(68°F)).
If low, check for leaks and add ºToyota Super Long Life Coolantº or similar high quality ethylene glycol based
non±silicate, non±amine, non±nitrite, and non±borate coolant with long±life hybrid organic acid technology
up to the ºFULLº 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 radiator cap or radiator filler
hole, and the coolant should be free from oil.
If excessively dirty, clean the coolant passages and replace the coolant.
(c) Reinstall the radiator cap.

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SL Energy±Conserving or ILSAC multi-
grade engine oil.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ºLº and ºFº marks on the dip-
stick.
If low, check for leakage and add oil up to the ºFº mark.
NOTICE:
Do not fill with engine oil above the ºFº mark.
3. REMOVE ENGINE UNDER COVER
4. REMOVE OIL PRESSURE SWITCH
5. INSTALL OIL PRESSURE GAUGE
6. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
7. CHECK OIL PRESSURE

At 3,000 rpm294 ± 588 kPa (3.0 ± 6.0 kgf/cm2, 43 ± 85 psi)
8. REMOVE OIL PRESSURE GAUGE
9. REINSTALL OIL PRESSURE SWITCH
(a) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive:
Part No. 08833±00080, THREE BOND 1344, LOCTITE
242 or equivalent
(b) Reinstall the oil pressure switch.

± SUSPENSION AND AXLETIRE PRESSURE MONITOR VALVE
SA±17
3013 Author: Date:
2005 SEQUOIA (RM1146U)

If installed in the reverse direction, the tire pressure
monitor valve may be damaged or fail to transmit sig-
nals when running at high speed.

If installing a new tire pressure monitor valve, write
down the ID number before installation.

It is necessary to registor an ID in the ECU after instal-
lation (See page DI±805).
(b) Install the washer on the tire pressure monitor valve from
the rim side and tighten with a nut.
Torque: 4.0 NVm (41 kgfVcm, 35 in.Vlbf)
NOTICE:

Check that there is no foreign matter on the washer
and nut.

If the tire pressure monitor valve is removed when the
tire is removed for replacement, check that there is no
damage or cuts, and no foreign matter such as mud,
dirt or sand attached to the grommet. Replace the
grommet with a new one if any of the defects men-
tioned above are found.

Check that there is no oil, water or lubricant around
the rim hole, tire pressure monitor valve, washer and
nut. Failing to do so may result in improper installa-
tion.
(c) After the tire is inflated, the valve nut may be loose. Re-
tighten the nut to the specified torque and then check for
air leaks with soapy water.
Torque: 4.0 NVm (41 kgfVcm, 35 in.Vlbf)
(d) Set the wheel disc to the mounting machine and install the
lower tire bead. Position the main body of the sensor as
in the shaded area shown in the illustration.
NOTICE:
If the sensor is positioned outside this area, it generates in-
terference with the tire bead, causing possible damage to
the sensor.
(e) Install the upper bead.
NOTICE:
Make sure that the tire bead and tool do not interfere with
the main body of the sensor and that the sensor is not
clamped by the bead.
5. INSTALL FRONT WHEEL
Torque: 103 NVm (1,050 kgfVcm, 76 ftVlbf)
6. INSTALL REAR WHEEL
Torque: 103 NVm (1,050 kgfVcm, 76 ftVlbf)
