DISASSEMBLY
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.
(b) Remove the nuts and plate washers.
(c) Remove the oil cooler and O±rings.

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.

The points shown in the rib sides and oil cooler near here
cannot be staked with SST. Use pliers or similar object
and be careful not to damage the core plates.
(b) Check the lock plate height (H) after completing the caulk-
ing.
Plate height (H): 7.4 ± 7.8 mm (0.2959 ± 0.3119 in.)
If not within the specified height, adjust the stopper bolt of the
handle again and caulk again.
