REASSEMBLY
1. INSTALL OIL COOLER TO LOWER TANK
(a) Install 2 new O±rings to the oil cooler.
(b) Install the oil cooler to the lower tank with the 2 plate
washers and 2 nuts.
Torque: 8.3 N´m (85 kgf´cm, 74 in.´lbf)
(c) Install the cooler pipes in the direction indicated in the il-
lustration.
Torque: 14.7 N´m (150 kgf´cm, 11 ft´lbf)
2. INSPECT LOCK PLATE FOR DAMAGE
HINT:

If the sides of the lock plate groove are deformed, reas-
sembly of the tank will be impossible.

Therefore, first correct any deformation with pliers or simi-
lar object. Water leakage will result if the bottom of the
lock plate groove is damaged or dented.
NOTICE:
The radiator can only be recaulked 2 times. After the 2nd
time, the radiator core must be replaced.
3. INSTALL NEW O±RINGS AND TANKS
(a) After checking that there are no foreign objects in the lock
plate groove, install a new O±ring without twisting it.
HINT:
When cleaning the lock plate groove, lightly rub it with sand pa-
per without scratching it.
(b) Install the tank without damaging the O±ring.
(c) Tap the lock plate with a soft±faced hammer so that there
is no gap between it and the tank.
4. ASSEMBLE SST
SST 09230±01010, 09231±14010
(a) Install the punch assembly to the overhaul handle, insert-
ing it in the hole in part A as shown in the illustration.
(b) While gripping the handle, adjust the stopper bolt so that
dimension B is as shown in the illustration.
Dimension B: 8.4 mm (0.331 in.)

14. CONNECT TIMING BELT TO CAMSHAFT TIMING
PULLEYS
HINT:
When re±using timing belt:

Check that the matchmark on the timing belt matches the
end of the No.1 timing belt cover.
If the matchmark does not align, shift the meshing of the
timing belt and crankshaft timing pulley until they align.

Align the matchmarks of the timing belt and camshaft tim-
ing pulleys.
(a) Remove any oil or water on the camshaft timing pulley,
and keep it clean.
(b) Install the timing belt, checking the tension between the
crankshaft timing pulley and intake camshaft timing
pulley.
15. SET TIMING BELT TENSIONER
(a) Using a press, slowly press in the push rod using 981 ±
9,807 N (100 ± 1,000 kgf, 220 ± 2,205 lbf) of force.
(b) Align the holes of the push rod and housing, pass a 1.5
mm hexagon wrench through the holes to keep the push
rod retracted.
(c) Release the press.
(d) Install the dust boot onto the tensioner.

GENERAL MAINTENANCE
These are maintenance and inspection items which are considered to be the owner's responsibility.
They can be done by the owner or they can have them done at a service shop.
These items include those which should be checked on a daily basis, those which, in most cases, do not
require (special) tools and those which are considered to be reasonable for the owner to do.
Items and procedures for general maintenance are as follows.
1. GENERAL NOTES

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 performed.

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 interval (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 an cause the engine to run poorly and increase exhaust emissions.
2. TIRES
(a) Check the pressure with a gauge. If necessary, adjust.
(b) Check for cuts, damage or excessive wear.
3. WHEEL NUTS
When checking the tires, check the nuts for looseness or for missing nuts. If necessary, tighten them.
4. TIRE ROTATION
Check the owner's manual supplement in which the maintenance schedule is shown.
5. WINDSHIELD WIPER BLADES
Check for wear or cracks whenever they do not wipe clean. If necessary, replace.
6. FLUID LEAKS
(a) Check underneath for leaking fuel, oil, water or other fluid.
(b) If you smell gasoline fumes or notice any leak, have the cause found and corrected.
7. DOORS AND ENGINE HOOD
(a) Check that all doors and the tailgate operate smoothly, and that all latches lock securely.
(b) Check that the engine hood secondary latch secures the hood from opening when the primary latch
is released.

Failure to do even one item an cause the engine to run poorly and increase 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 ºFULLº and ºLOWº lines on the see±through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, 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 upper and lower level lines on the case.
6. BRAKE FLUID LEVEL
Check that the brake fluid levels are near the upper level line on the see±through reservoirs.
7. ENGINE DRIVE BELT
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

Check the level on the dipstick.

The level should be in the ºHOTº or ºCOLDºrange depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all positions from ºPº to ºLº,
and then shift into ºPº position.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re±insert the dipstick 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 until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speeds, in hot weather, in heavy traffic or pulling a trailer.
11. EXHAUST SYSTEM
If any change in the sound of the exhaust or smell of the exhaust fumes is noticed, have the cause located
and corrected.

(f) Connect a LEXUS hand±held tester to the DLC3.
(See step 1 in check fuel pump operation (a) to (e))
(g) Measure the fuel pressure.
Fuel pressure:
304 ± 343 kPa (3.1 ± 3.5 kgf/cm
2, 44 ± 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the fuel hoses and connections, fuel
pump, fuel filter and fuel pressure regulator.
(h) Disconnect the LEXUS hand±held tester from the DLC3.
(i) Start the engine.
(j) Measure the fuel pressure at idle.
Fuel pressure:
304 ± 343 kPa (3.1 ± 3.5 kgf/cm
2, 44 ± 50 psi)
(k) Stop the engine.
(l) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure: 147 kPa (1.5 kgf/cm
2, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure
regulator and/or injectors.
(m) After checking fuel pressure, disconnect the negative (±)
terminal cable from the battery and carefully remove SST
to prevent gasoline from splashing.
SST 09268±45014
(n) Reconnect the fuel inlet hose to the fuel pipe support with
2 new gaskets and the union bolt.
Torque: 29 N´m (300 kgf´cm, 21 ft´lbf)
(o) Reconnect the negative (±) terminal cable to the battery.
(p) Check for fuel leaks.
3. INSPECT FUEL PUMP
(a) Remove the rear seat cushion.
(b) Remove the 3 cap nuts and floor service hole cover.
(c) Disconnect the fuel pump & sender gauge connector.
(d) Using an ohmmeter, measure the resistance between ter-
minals 4 and 5.
Resistance: 0.2 ± 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
(e) Inspect the fuel pump operation.
Connect the positive (+) lead from the battery to terminal
4 of the connector, and the negative (±) lead to terminal
5. Check that the fuel pump operates.
NOTICE:

These tests must be done quickly (within 10 seconds)
to prevent the coil burning out.

Keep the fuel pump as far away from the battery as
possible.

Always do the switching at the battery side.
