1. REMOVE CUSHION FROM RADIATOR
2. ASSEMBLE SST
SST 09230±01010
(a) Install the claw to the overhaul handle, inserting it in the
hole in part ºAº as shown in the diagram.
(b) While gripping the handle, adjust the stopper bolt so that
dimension ºBº shown in the diagram is 0.2 ± 0.5 mm
(0.008 ± 0.020 in.).
NOTICE:
If this adjustment is not done, the claw may be damaged.
3. UNCAULK LOCK PLATES
Using SST to release the caulking, squeeze the handle until
stopped by the stopper bolt.
SST 09230±01010
4. REMOVE TANKS AND O±RINGS
(a) Lightly tap the bracket of the radiator (or radiator hose in-
let or outlet) with a soft±faced hammer and remove the
tank.
(b) Remove the O±ring.
5. A/T:
REMOVE OIL COOLER FROM LOWER TANK
(a) Remove the pipe.

REASSEMBLY
1. A/T:
INSTALL OIL COOLER TO LOWER TANK
(a) Clean the O±ring contact surface of the lower tank and oil
cooler.
(b) Install a new O±rings (1) to the oil cooler (2).
(c) Install the oil cooler with the O±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 pipe (6).
Torque: 14.7 N´m (150 kgf´cm, 11 ft´lbf)
2. INSPECT LOCK PLATE
Inspect the 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, Therefore, repair
or replace if necessary.
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.

(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 shown in the diagram.
Dimension ºBº: 8.4 mm (0.34 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.
