15. REMOVE CAMSHAFT
(a) Using several steps, loosen and remove the 10 camshaft
bearing cap bolts uniformly in the sequence shown in the
illustration.
(b) Remove 5 camshaft bearings.
(c) Remove the camshaft.
(d) Tie the timing chain as shown in the illustration.
NOTICE:

Be careful not to drop anything inside the timing
chain cover.

Do not expose the chain to water, and prevents dust.
16. REMOVE CAMSHAFT TIMING GEAR ASSY
(a) Clamp the camshaft in a vise, and make sure the cam-
shaft timing gear does not rotate.
(b) Cover all the oil ports with vinyl tape except an advance
side port shown in the illustration.
(c) Put air pressure into the oil port with 150 kpa (1.5 kgf/cm
2
21 psi), and turn the camshaft timing gear to the advance
direction (counterclockwise) by hand.
CAUTION:
Cover the ports with shop rag to avoid oil splashing.
HINT:
Depending on the air pressure, the camshaft timing gear will
turn to the advance angle side without applying force by hand.
Also, under the condition that the pressure can be hardly ap-
plied because of the air leakage from the port, there may be the
case that the lock pin could be hardly released.

(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.

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 lines, 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.
