1. INSPECT RADIATOR CAP
NOTICE: When performing steps (a) and (b) below, keep
the radiator pump 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 relief valve.
Pump speed:
1 push/ 3 seconds or more
NOTICE: Push the pump at a constant speed.
If air is not coming from the relief valve, replace the
radiator cap.
(b) Pump the tester several times and measure the relief
valve opening pressure.
Pump speed:
1 at time
1 push/1 second or less
2nd time or more
Any speed
Standard opening pressure:
74±103 kPa
(0.75±1.05 kgf/cm
, 10.7 ± 14.9 psi)
Minimum opening pressure:
59 kPa (0.6 kgf/cm
, 8.5 psi)
If the opening pressure is less than minimum, replace
the radiator cap.
RADIATOR
RADIATOR 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 care±
full not to deform the fins of the radiator core. If the
cleaner nozzle pressure is 2,942 ± 3,432 kPa (30 ± 35
kgf/cm
, 427 ± 498 psi), keep a distance of at least 40
cm (15.75 in.) between the radiator core and cleaner
nozzle.

2. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap
tester.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
, 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.
RADIATOR REMOVAL
1. DISCONNECT NEGATIVE (±) TERMINAL CABLE
FROM BATTERY
CAUTION: Work must be started after 90 seconds from
the time the ignition switch is turned to the ªLOCKº
position and the negative (±) terminal cable is discon±
nected from the battery.

RADIATOR DISASSEMBLY
1. ASSEMBLE SST
SST 09230±01010
(a) Install the claw to the overhaul handle, inserting it in
the hole in part ªAº as shown in the diagram.
(b) While gripping the handle, adjust the stopper bolt so
that dimension ªBº shown in the diagram is 0.2±0.5
mm (0.008±0.020 in.).
NOTICE: If this adjustment is not performed, the claw
may be damaged.

ASSEMBLY

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.
