Radiator Cap Tester
1. INSPECT COOLING SYSTEM FOR LEAKS
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.
(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.
A65935
HINT:
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.
2. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
(a) The engine coolant level should be between the ”LOW” and ”FULL” line.
HINT:
If low, check for leaks and add ”Toyota Long Life Coolant” or equivalent up to the ”FULL” line.
3. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot, as fluid and steam can be blown out under pressure.
(b) Check if there is any excessive deposits of rust or scale around the radiator cap and radiator filler hole;
the coolant should be free from oil.
HINT:
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.

THERMOSTAT
HINT:
The thermostat is numbered with the valve opening tempera-
ture.
P13560
(a) Immerse the thermostat in water and gradually heat the
water.
(b) Check the valve opening temperature.
Valve opening temperature:
80 to 84
C (176 to 183
F)
HINT:
If the valve opening temperature is not as specified, replace the
thermostat.
P00436
(c) Check the valve lift.
Valve lift: 10 mm (0.39 in.) or more at 95
C (203
F)
HINT:
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 77
C (171
F)).
P24125
HINT:
If not closed, replace the thermostat.
2. RADIATOR CAP SUB–ASSY
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 step (a) and (b) below, keep the tes-
ter at an angle of over 30
above the horizontal.

Radiator Cap Tester
(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:
The above pump speed is for the first pump only (in order
to close the vacuum valve). After the first pump, the pump
speed can be reduced.
Standard opening pressure:
74 to 103 kPa (0.75 to 1.05 kgf/cm
2
, 10.7 to 14.9 psi)
Minimum opening pressure:
59 kPa (0.6 kgf/cm
2
, 8.5 psi)
30
or more
Radiator Cap
Z00570
HINT:
Use the tester’s maximum reading as the opening pressure.
If the opening pressure is less than minimum, replace the radia-
tor cap.

COOLING FAN SYSTEM
COOLING FAN SYSTEM
ON–VEHICLE INSPECTION
1. CHECK COOLING FAN OPERATION WITH LOW TEMPERATURE (Below 83
C (181
F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
HINT:
If not, check the cooling fan relay and water temperature sensor, and check for separated connector or se-
vered wire between the cooling fan relay and water temperature sensor.
(c) Disconnect the water temperature sensor connector.
(d) Check that the cooling fan rotates.
If not, check the fuses, cooling fan relay, ECM and cooling fan, and check for a short circuit between the
cooling fan relay and water temperature sensor.
(e) Reconnect the water temperature sensor connector.
2. CHECK COOLING FAN OPERATION WITH HIGH TEMPERATURE (Above 93
C (199
F))
(a) Start the engine, and raise coolant temperature to above 93
160C6–02
C (199
F).
HINT:
Coolant temperature is the detected value by the water temperature sensor on the water outlet.
(b) Check that the cooling fan rotates.
HINT:
If not, replace the water temperature sensor.
3. INSPECT COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter to the connector.
(c) Check that the cooling fan rotates smoothly, and check the reading on the ammeter.
Standard amperage:
Approx. 8.0 – 12.0 A at 20
C (68
F)
(d) Reconnect the cooling fan connector.
