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

INSTALLATION
1. INSTALL WATER PUMP
(a) Install a new O±ring to the water bypass pipe end.
(b) Apply soapy water to the O±ring.
(c) Connect the water pump to the water bypass pipe end.
(d) Install the water pump and a new gasket with the 5 bolts,
2 stud bolts and nut. Uniformly tighten the bolts, stud bolts
and nut in several passes.
Torque:
Bolt: 21 N´m (215 kgf´cm, 15 ft´lbf)
Stud bolt and nut: 18 N´m (185 kgf´cm, 13 ft´lbf)
2. INSTALL WATER INLET AND INLET HOUSING AS-
SEMBLY
(a) Remove any old packing (FIPG) material and be careful
not to drop any oil on the contact surfaces of the water in-
let housing and water pump.

Using a razor blade and gasket scraper, remove all
the old packing (FIPG) material from the gasket sur-
faces and sealing groove.

Thoroughly clean all components to remove all the
loose material.

Using a non±residue solvent, clean both sealing
surfaces.
(b) Apply seal packing to the sealing groove of water inlet
housing as shown in the illustration.
Seal packing: Part No. 08826±00100 or equivalent

Install a nozzle that has been cut to a 2 ± 3 mm (0.08
± 0.12 in.) opening.

Parts must be assembled within 3 minutes of ap-
plication. Otherwise the material must be removed
and reapplied.

Immediately remove nozzle from the tube and rein-
stall cap.
(c) Install a new O±ring to the water inlet housing.
(d) Apply soapy water on the O±ring.
(e) Attach the water inlet housing end to the front water by-
pass joint hole.
