INSPECTION
INSPECT THERMOSTAT
HINT:
The thermostat is numbered with the valve opening tempera-
ture.
(a) Immerse the thermostat in water, and gradually heat the
water.
(b) Check the valve opening temperature.
Valve opening temperature: 80 - 84°C (176 - 183°F)
If the valve opening temperature is not as specified, replace the
thermostat.
(c) Check the valve lift.
Valve lift: 8 mm (0.31 in.) or more at 95°C (203°F)
If the valve lift is not as specified, replace the thermostat.
(d) Check that the valve is fully closed when the thermostat
is at low temperatures (below 40°C (104°F)).
If not closed, replace the thermostat.

ON-VEHICLE CLEANING
CLEAN RADIATOR
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)
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.
4. REINSTALL RADIATOR CAP

SST 09230-01010
(a) Install the claw to the overhaul handle, inserting it in the
hole in part A as shown in the diagram.
(b) While gripping the handle, adjust the stopper bolt so that
dimension B is as 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 dam-
aged.
2. UNCAULK LOCK PLATES
Using SST to release the caulking, squeeze the handle until
stopped by the stopper bolt.

REASSEMBLY
1. A/T:
INSTALL OIL COOLER TO LOWER TANK

cooler.
(b) Install new O rings to the oil cooler.
(c) Install the oil cooler with the O-rings to the lower tank.

Torque:
Nut A: 15 N´m (150 kgf´cm, 11 ft´lbf)
Nut B and C: 8.5 N´m (85 kgf´cm, 75 in.´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 like
object. Water leakage will result if the bottom of the lock
plate groove is damaged or dented or dented. There fore,
repair or replace if necessary.
3. INSTALL NEW O-RINGS AND TANKS
(a) After checking that there are no foreign objects in the lock
plate groove, install a 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.
