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

4. REMOVE RADIATOR ASSEMBLY
(a) Disconnect the No.1 cooling fan connector.
(b) w/ A/C:
Disconnect the No.2 cooling fan connector.
(c) Disconnect the radiator upper hose from the radiator.
(d) Disconnect the radiator lower hose from the water inlet.
(e) Disconnect the 2 A/T oil cooler hoses from the radiator.
HINT:
Plug the hose to prevent oil from escaping.
(f) Remove the 2 bolts and 2 upper radiator supports.
Torque: 12 N´m (120 kgf´cm, 9 ft´lbf)
HINT:
(A/T only):
After installation, check that the rubber cushion (A) of the sup-
port is not depressed.
(g) Remove the radiator assembly.
(h) Remove the 2 radiator lower supports and the lower ra-
diator hose.

ON-VEHICLE INSPECTION
1. CHECK COOLING FAN OPERATION WITH LOW TEM-
PERATURE (Below 83°C (181°F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
If not, check the cooling fan relay and ECT switch, and check
for a separated connector or severed wire between the cooling
fan relay and ECT switch.
(c) Disconnect the ECT switch connector.
(d) Check that the cooling fan rotates.
If not, check the engine main relay, cooling fan relay, cooling
fan, fuses, and check for short circuit between the cooling fan
relay and ECT switch.
(e) Reconnect the ECT switch connector.
2. CHECK COOLING FAN OPERATION WITH HIGH TEM-
PERATURE (Above 94°C (201°F))
(a) Start the engine, and raise coolant temperature to above
94°C (201°F).
(b) Check that the cooling fan rotates.
If not, replace the ECT switch.
3. INSPECT NO.1 COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage:
M/T5.7 - 7.7 A
A/T8.6 - 11.6 A
(d) Reconnect the cooling fan connector.
4. INSPECT NO.2 COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage: 6.4 - 7.4 A
(d) Reconnect the cooling fan connector.
