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.

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 is as shown in the illustration.
Dimension: 8.4 mm (0.331 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.
The points shown in the illustration and oil cooler near
here (A/T) cannot be staked with the 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: 7.40 ± 7.80 mm (0.2913 ± 0.3071 in.)
If not within the specified height, adjust the stopper bolt of the
handle again and caulk again.
6. INSTALL ECT SWITCH
(a) Install a new O±ring to the ECT switch.
(b) Install the ECT switch.
7. INSTALL DRAIN PLUG
(a) Install a new O±ring to the drain plug.
(b) Install the drain plug.
8. INSPECT FOR WATER LEAKS
(a) Plug the inlet and outlet pipes of the radiator with SST.
SST 09230±01010
(b) Using a radiator cap tester, apply pressure to the radiator.
Test pressure: 177 kPa (1.8 kgf/cm
2, 26 psi)
(c) Submerge the radiator in water.
(d) Inspect for leaks.
HINT:
On radiators with resin tanks, there is a clearance 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 sub-
merged in water. Therefore, before doing the water leak test,
first swish the radiator around in the water until all air bubbles
disappear.
