ON±VEHICLE CLEANING
Using water or a steam cleaner, remove any mud or dirt from the radiator core.
NOTICE:
If using a high pressure type cleaner, be careful not to deform the fins of the radiator core. (i.e. Main-
tain a distance between the cleaner nozzle and radiator core.)

ON±VEHICLE INSPECTION
1. REMOVE RADIATOR CAP
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
2. INSPECT RADIATOR CAP
NOTICE:

If the radiator cap has contaminations, always rinse
it with water.

Before using a radiator cap tester, wet the relief valve
and pressure valve with engine coolant or water.

When performing steps (a) and (b) below, keep the
tester at an angle of over 30° above the horizontal.
(a) Using a radiator cap tester, slowly pump the tester and
check that air is coming from the vacuum valve.
Pump speed: 1 push/(3 seconds or more)
NOTICE:
Push the pump at a constant speed.
If air is not coming from the vacuum valve, replace the radiator
cap.
(b) Pump the tester, and measure the relief valve opening
pressure.
Pump speed: 1 push within 1 second
NOTICE:
This pump speed is for the first pump only (in order to close
the vacuum valve). After this, the pump speed can be re-
duced.
Standard opening pressure:
74 ± 103 kPa (0.75 ± 1.05 kgf/cm
2, 10.7 ± 14.9 psi)
Minimum opening pressure:
59 kPa (0.6 kgf/cm
2, 8.5 psi)
HINT:
Use the tester's maximum reading as the opening pressure.
If the opening pressure is less than minimum, replace the radia-
tor cap.
3. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant, and attach a radiator cap tes-
ter.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump
for leaks. If no external leaks are found, check the heater core,
cylinder block and head.

hole in part ºAº as shown in the diagram.
(b) While gripping the handle, adjust the stopper bolt so that
dimension ºBº is as shown in the illustration.

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.

(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.

(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.
