COOLANT CHECK
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR
RESERVOIR
The engine coolant level should be between the ºLOWº and
ºFULLº lines.
If low, check for leaks and add engine coolant 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, replace the coolant.
(c) Reinstall the radiator cap. EG±330
± ENGINECOOLING SYSTEM

(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: 7.4 NVm (75 kgfVcm, 65 in.Vlbf)
WATER PUMP INSTALLATION
1. INSTALL WATER PUMP
(a) Install a new O±ring to the cylinder block.
(b) Install a new gasket to the water pump.
(c) Connect the water pump to the water bypass pipe. Do not
install the nut yet.
(d) Install the water pump with the 2 bolts (A) and 4 bolts (B).

(f) 2JZ±GTE:
Connect the No.3 turbo water hose to the water pump.
(g) 2JZ±GE:
Install the generator mounting bolt.
Torque: 37 NVm (380 kgfVcm, 27 ftVlbf)
(h) 2JZ±GE:
Tighten the generator mounting nut.
Torque: 37 NVm (380 kgfVcm, 27 ftVlbf)
(i) 2JZ±GE:
Install the engine wire bracket with the bolt.

INSTALL OIL COOLER TO LOWER TANK
(a) Clean the O±ring contact surface of the lower tank and oil
cooler.
(b) Install new O±ring (1) to the oil cooler (2).

HINT: Face the inlet pipes in the same direction they were be-
fore disassembly.
2. INSPECT LOCK PLATE
Inspect the lock plate for damage.
HINT:
wIf the sides of the lock plate groove are deformed,
reassembly of the tank will be impossible.
wTherefore, first correct any deformation with pliers or
similar object. Water leakage will result if the bottom of
the lock plate groove is damaged or dented. Therefore,
repair or replace if necessary.
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 paper 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. EG±350
