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.

REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap from the water outlet.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) Loosen the radiator drain plug and engine drain plugs,
and drain the coolant.
(c) Close the drain plugs.
Torque:
RH engine drain plug on EGR cooler:
7 N´m (70 kgf´cm, 61 in.´lbf)
LH engine drain plug on union:
13 N´m (130 kgf´cm, 9 ft´lbf)
2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.
Use of improper coolants may damage engine cool-
ing system.
Use ºToyota Long life Coolantº or equivalent and
mix it with plan water according to the manufactur-
er's directions.
Using of coolant which includes more than 50 %
(freezing protection down to ±35°C (±31°F) or 60 %
(freezing protection down to ±50°C (±58°F)) of eth-
ylene±glycol is recommended but not more than 70
%.
NOTICE:
Do not use an alcohol type coolant or plain water
alone.
The coolant should be mixed with plain water (prefer-
ably demineralized water or distilled water).
Capacity: 9.2 liters (9.7 US qts, 8.1 lmp. qts)
(b) Install the radiator cap.
(c) Start the engine, and bleed the cooling system.
(d) If necessary, refill coolant into the reservoir up to the
ºFULLº line.
