(b) Install the timing belt in the following order: 1. Camshaft timing pulley
2. Supply pump drive pulley
3. Water pump pulley
4. Crankshaft timing pulley
5. No. 2 idler pulley
6. Oil pump pulley
7. No. 1 idler pulley
(c) Install the timing belt tensioner. (1) Using a press, slowly press in the push rod with
pressure 981 to 9,807 N (100 to 1,000 kgf, 200 to
2,205 lbf).
(2) Align the holes of the push rod and the housing, in- sert hexagon wrench (1.27 mm) through the holes
to keep the setting position of the push rod.
(3) Release the press.
(4) Temporarily install the tensioner with bolt (A).
(5) Turn the tensioner clockwise and temporarily install the other bolt.
(6) Alternately tighten the 2 bolts.
Torque: 21 N´m (214 kgf´cm, 15 ft´lbf)
(7) Remove the hexagon wrench from the tensioner.
23. CHECK VALVE TIMING
(a) Slowly turn the crankshaft 2 complete revolutions (720
)
from TDC to TDC.
NOTICE:
Always turn the crankshaft clockwise.

(3) Put air pressure into two broken paths (the advance
side path and the retard side path) with about 150
kPa {1.5 kgf
cm}.
CAUTION:
Cover the pathes with shop rag to avoid oil splashing.
(4) Confirm if the camshaft timing gear assembly re-volves in the timing advance direction when weak-
ening the air pressure of the timing retard path.
HINT:
The lock pin is released, and camshaft timing gear, revolves in
the advance direction. (5) When the camshaft timing gear comes to the mostadvanced position, take out the air pressure of the
timing retard side path, and then, take out that of
timing advance side path.
CAUTION:
Camshaft timing assembly gear occasionally shifts to the
retard side abruptly, if the air compression of the advanced
side path is released before retard side path. It often
causes the breakage of the lock pin.
(c) Check smooth revolution (1) Revolve the camshaft timing gear assembly withinthe movable range except for the most retarded
position several times, and check the smooth revo-
lution.
CAUTION:
Be sure to perform this check by hand, instead of air pres-
sure.
(d) Check the lock in the most retarded position. (1) Confirm that the camshaft timing gear assembly islocked at the most retarded position.

19. REMOVE CAMSHAFT TIMING GEAR ASSY
(a) Grip the camshaft with a vice, and confirm that the gear is locked.
CAUTION:
Be careful not to damage the camshaft.
(b) Cover 4 oil paths of cam journal with vinyl tape as shown in the illustration.
HINT:
Two advance side paths are provided in the groove of the cam-
shaft. Plug one of the path with a rubber piece.
(c) Break through the tapes of the advance side path and the retard side path on the opposite side of the groove.
(d) Put air pressure into two broken paths (the advance side path and the retard side path) with about 150 kPa {1.5 kgf/
cm
2}.
CAUTION:
Cover the pathes with shop rag to avoid oil splashing.
(e) Confirm if the camshaft timing gear assembly revolves in the timing advance direction when weakening the air
pressure of the timing retard path.
HINT:
The lock pin is released, and camshaft timing gear revolves in
the advance direction.
(f) When the camshaft timing gear comes to the most ad- vanced position, take out the air pressure of the timing re-
tard side path, and then, takeout that of timing advance
side path.
CAUTION:
Camshaft timing gear assembly occasionally shifts to the
retard side abruptly, if the air compression of the advanced
side path is released before retard side paths. It often
causes the breakage of the lock pin.

COOLING SYSTEM (1AZ±FE)
ON±VEHICLE INSPECTION
1. INSPECT COOLING SYSTEM FOR LEAKS
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot. Ther-
mal expansion will cause hot engine coolant and steam to
blow out from the radiator.
(a) Remove the radiator support opening cover.
(b) Remove the engine room cover side.
(c) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(d) Warm up the engine.
(e) Pump it to 137 kPa (1.4 kgf/cm
2, 19.9 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator and water
pump for leaks. If there are no signs or traces of external coolant
leaks, check the heater core, cylinder block and head.
(f) Reinstall the engine room cover side.
(g) Reinstall the radiator support opening cover.
2. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
(a) The engine coolant should be between the ºLOWº and ºFULLº li\
nes, when the engine is cold.
If low, check for leaks and add ºToyota Long Life Coolantº or equivalent up to the ºFULLº line.
3. 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. Thermal expansion will cause hot engine coolant and steam to\
blow out from the radiator.
(b) Check if there is any excessive deposits of rust or scale around the radiator\
cap and radiator filler hole; the coolant should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.

1. CHECK ENGINE OIL LEVEL
(a) After warm up the engine and then 5 minutes after the engine stop, oil l\
evel should be between the low level and full level marks of the dipstick.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.

If the quality is visibly poor, replace the oil. Oil grade:
API grade ºSJº Energy±Conserving, ºSLº Energy±
Conserving or ILSAC multi grade engine oil. Recom-
mended viscosity is as shown in the illustration.
3. REMOVE OIL PRESSURE SWITCH ASSY
(a) Disconnect the oil pressure switch connector.
(b) Using a deep socket wrench 24mm, remove the oil pres- sure switch.
4. INSTALL OIL PRESSURE GAUGE
