(f) Observe the following when connecting the fuel tube con-
nector (quick type):
(1) Check if there is any damage or foreign objects in
the connected part of the pipe.
(2) Match the axis of the connector with the axis of the
pipe, and push into the connector until a ºclickº
sound is heard. If the connection is tight, apply a
small amount of fresh engine oil on the tip of the
pipe.
(3) After finishing the connection, pull the pipe and the
connector to ensure it is secure.
(4) Check to make sure no fuel leak is present.
If the result is not specified, repair or replace.
(5) Install the fuel pipe clamp to the connector.
(6) Check to make sure no fuel leak is present.
If the result is not specified, repair or replace.
(g) Observe the following when disconnecting the fuel tube
connector (metallic type):
HINT:
The structure of the metallic connector is shown on the left.
(1) Check if there is any dirt in the pipe and around the
connector before disconnecting the fuel tube con-
nector. If necessary, clean the dirt away.
(2) Assemble SST to the connecting part, as shown in
the illustration.

(3) Turn the SST, align the retainers inside the connec-
tor with the SST chamfered parts and insert the SST
into the connector.
(4) While holding the SST, pull the connector towards
the SST to put the retainers on the SST chamfered
parts.
(5) Slide the SST and connector together towards the
fuel tube assembly.
(h) Observe the following when connecting the fuel tube con-
nector (metallic type):
(1) Check if there is any damage or foreign objects in
the connected part of the pipe.
(2) Match the axis of the connector with the axis of the

If the result is not specified, repair or replace.
(i) Observer the following when handling the nylon tube:
(1) Pay attention not to turn the connected part of the
nylon tube and the quick connector with tube when
connecting them.
(2) Pay attention not to kink the nylon tube.
(3) Do not remove the nylon tube.
(4) Do not close the piping with the nylon tube by bend-
ing it.

INSPECTION
1. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance: 0.2 to 3.0 W at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
2. INSPECT FUEL PUMP OPERATION
(a) Connect the lead wire to the fuel pump.
(b) Connect the positive (+) lead from the battery to terminal
1 of the connector, and the negative (±) lead to terminal
2. Check that the fuel pump operates.
NOTICE:

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

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

Always do switching on the battery side.
If operation is not as specified, replace the fuel pump and/or
read wire.
(c) Disconnect the lead wire to the fuel pump.

INSPECT OIL CONTROL VALVE OPERATION
Connect the positive
lead to terminal 1 of the connector and
the negative  lead to terminal 2, then check the movement of
the valve.
If operation is not as specified, replace the oil control valve.

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.

INSPECTION
1. INSPECT WATER PUMP
(a) Visually check the air hole and water hole for coolant leak-
age.
If leakage is found, replace the water pump and timing belt.
(b) Turn the pulley, and check that the water pump bearing
moves smoothly and quietly.
If necessary, replace the water pump.
2. INSPECT FLUID COUPLING
(a) Remove the 4 nuts and fan from the fluid coupling.
(b) Check that the fluid coupling is not damaged and that no
silicon oil leaks.
If necessary, replace the fluid coupling.
(c) Reinstall the fan to the fluid coupling with the 4 nuts.
Torque: 8.5 N´m (85 kgf´cm, 75 in.´lbf)
3. INSPECT FAN PULLEY BRACKET
Check the turning smoothness of the fan pulley.
If necessary, replace the pulley bracket.
4. INSPECT TIMING BELT COMPONENTS
