REASSEMBLY
1. A/T:
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 nuts.
Torque: 8.3 N´m (85 kgf´cm, 74 in.´lbf)
(c) Install the cooler pipe 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 the 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 ºAº as shown in the illustration.
(b) While gripping the handle, adjust the stopper bolt so that
dimension ºBº is as shown in the illustration.
Dimension: 8.4 mm (0.331 in)
5. CAULK LOCK PLATE
(a) Lightly press SST against the lock plate in the order
shown in the illustration. After repeating this a few times,
fully caulk the lock plate by squeezing the handle until
stopped by the stopper plate.
SST 09230±01010
HINT:
Do not stake the areas protruding around the pipes,
brackets or tank ribs.
The points shown in the illustration and oil cooler near
here (A/T) cannot be staked with the SST. Use pliers or
similar object and be careful not to damage the core
plates.

COOLANT
INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ºLOWº and ºFULLº lines, when the engine is cold.
If low, check for leaks and add ''Toyota Long Life Coolantº or Equivalent up to the ºFULLº line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap from the water outlet.
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 water outlet
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.
