RADIATOR ASSEMBLY
(See Components for Disassembly and Assembly)
1. A/T:
INSTALL OIL COOLER TO LOWER TANK
(a) Clean the 0±ring contact surface of the lower tank
and oil cooler.
(b) Install new 0±rings (1) to the oil cooler (2).
(c) Install the oil cooler with the 0±rings to the lower
tank (3).
(d) Install the plate washers (4) and nuts (5). Torque the
nuts.
Torque: 8.3 N±m (85 kgf±cm, 74 in.±lbf)
(e) Install the pipes (6).
Torque: 22 N±m (220 kgf±cm, 16 ft±lbf)
HINT: Face the pipes in the same direction as before
disassembly.4. A/T:
REMOVE OIL COOLER FROM LOWER TANK
(a) Remove the pipes.
HINT: Make a note of the direction to face the pipes.
(b) Remove the nuts and plate washers.
(c) Remove the oil cooler and 0±rings. 3. REMOVE TANKS AND O±RINGS
(a) Lightly tap the radiator hose inlet (or outlet) with a
soft±faced hammer and remove the tank.
(b) Remove the 0±ring. 2. UNCAULK LOCK PLATES
Using SST to release the caulking, squeeze the handle
until stopped by the stopper bolt.

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. There±
fore, repair or replace if necessary.
4. ASSEMBLE SST
SST 09230±01010
(a) Install the punch assembly to the overhaul handle,
inserting it in the hole in part ªAº as shown in the
illustration.
(b) While gripping the handle, adjust the stopper bolt so
that dimension ªBº shown in the diagram is 7.7 mm
(0.03 in.) 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 0±ring.
(c) Tap the lock plate with a soft±faced hammer so that
there is no gap between it and the tank.
5. CAULK LOCK PLATE
(a) Lightly press SST against the lock plate in the order
shown in the illustration.

6. INSPECT FOR WATER LEAKS
(a) Tighten the drain cock.
(b) Plug the inlet and outlet pipes of the radiator with
SST.
SST 09230 ± 01010
(c) Using a radiator cap tester, apply pressure to the
radiator.
Test pressure:
177 kPa (1.8 kgf/cm, 26 psi) (b) Check the lock plate height (H) after completing the
caulking.
Plate height:
7.75±8.25 mm (0±3051±0.3248 in.)
If not within the specified height, adjust the stopper
bolt of the handle again and perform the caulking
again.wThe points shown in the illustration and oil cooler
near here (A/T) cannot be staked with the SST.
Use a plier or like object and be careful not to
damage the core plates. 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:
wDo not stake the areas protruding around the
pipes, brackets or tank ribs.

(d) Inspect for water leaks.
HINT: On radiators with resin tanks, there is a clear±
ance between the tank and lock plate where a minute
amount of air will remain, giving the appearance of an
air leak when the radiator is submerged in water.
Therefore, before performing the water leak test, first
switch the radiator around in the water until all air
bubbles disappear.
7. PAINT LOCK PLATES
HINT: If the water leak test checks out okay, allow the
radiator to completely dry and then paint the lock
plates.

1. INSPECT ENGINE COOLANT TEMPERATURE
SWITCH
(a) Using an ohmmeter, check that there is no continuity
between the terminals when the engine coolant tem±
perature is above 93C (199F).
(b) Using an ohmmeter, check that there is continuity
between the terminals when the engine coolant tem±
perature is below 83C (181 F).
If continuity is not as specified, replace the switch. 2. DISCONNECT ENGINE COOLANT TEMPERATURE
