9. CLEAN VALVES
(a) Using a gasket scraper, chip off any carbon from the valve
head.
(b) Using a wire brush, thoroughly clean the valve.
10. INSPECT VALVE STEMS AND GUIDE BUSHINGS
(a) Using a caliper gauge, measure the inside diameter of the
guide bushing.
Bushing inside diameter:
5.510 to 5.530 mm (0.2169 to 0.2177 in.)
(b) Using a micrometer, measure the diameter of the valve
stem.
Valve stem diameter:
Intake5.470 to 5.485 mm (0.2154 to 0.2159 in.)
Exhaust5.465 to 5.480 mm (0.2152 to 0.2157 in.)
(c) Subtract the valve stem diameter measurement from the
guide bushing inside diameter measurement.
Standard oil clearance:
Intake0.025 to 0.060 mm (0.0010 to 0.0024 in.)
Exhaust0.030 to 0.065 mm (0.0012 to 0.0026 in.)
Maximum oil clearance:
Intake0.08 mm (0.0031 in.)
Exhaust0.10 mm (0.0039 in.)
If the clearance is greater than maximum, replace the valve and
guide bushing. (See page EM±56)
11. INSPECT AND GRIND VALVES
(a) Grind the valve enough to remove pits and carbon.
(b) Check that the valve is ground to the correct valve face
angle.
Valve face angle: 44.5°

On±pavement and off±road
driving tips
This vehicle belongs to the utility vehicle class. Utility
vehicles have a significantly higher rollover rate than
other types of vehicles. This vehicle will handle and
maneuver differently from an ordinary passenger car be-
cause it is designed for off±road use also. In addition,
this vehicle has a higher ground clearance and center of
gravity than that of an ordinary passenger car. This
vehicle design feature causes this type of vehicle to be
more likely to rollover. Failure to operate this vehicle
correctly may result in loss of control, accidents or
vehicle rollover causing death or serious injury. Be sure
to read ªOff±road vehicle precautionsº on page 334 in
Section 2 and ªOff±road driving precautionsº on page
365 in Section 3.
Leak detection pump
This pump performs fuel evaporation leakage check. This
check is done approximately five hours after the engine is
turned off. So you may hear sound coming from under-
neath the luggage compartment for several minutes. It
does not indicate a malfunction.

334
2005 SEQUOIA from Aug. '04 Prod. (OM34424U)
This vehicle belongs to the utility ve-
hicle class, which has higher ground
clearance and narrower tread in relation
to the height of its center of gravity to
make it capable of performing in a wide
variety of off±road applications. Specific
design characteristics give it a higher
center of gravity than ordinary passen-
ger cars. This vehicle design feature
causes this type of vehicle to be more
likely to rollover. And, utility vehicles
have a significantly higher rollover rate
than other types of vehicles. An advan-
tage of the higher ground clearance is
a better view of the road allowing you
to anticipate problems. It is not de-
signed for cornering at the same
speeds as ordinary passenger cars any
more than low±slung sports cars de-
signed to perform satisfactorily under
off±road conditions. Therefore, sharp
turns at excessive speeds may cause
rollover.CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle:

In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Therefore, the driver and all
passengers should fasten their seat
belts whenever the vehicle is mov-
ing.

Avoid sharp turns or abrupt maneu-
vers, if at all possible. Failure to
operate this vehicle correctly may
result in loss of control or vehicle
rollover causing death or serious
injury.

Loading cargo on the roof luggage
carrier will make the center of the
vehicle gravity higher. Avoid high
speeds, sudden starts, sharp turns,
sudden braking or abrupt maneu-
vers, otherwise it may result in loss
of control or vehicle rollover due to
failure to operate this vehicle cor-
rectly.

NOTICE
Tighten all joints securely.
Otherwise, the extension may
come off and it may damage
the paint or vehicle body.
6. After making sure that no one
is in the vehicle, raise it high
enough so that the spare tire
can be installed.
Remember you will need more ground
clearance when putting on the spare
tire than when removing the flat tire.
