(d) Inspect for water leaks.
HINT: On radiators with resin tanks, there is a clear±
ance 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 submerged in water.
Therefore, before performing the water leak test, first
switch the radiator around in the water until all air
bubbles disappear.
7. PAINT LOCK PLATES
HINT: If the water leak test checks out okay, allow the
radiator to completely dry and then paint the lock
plates.

INSPECTION
1. INSPECT ENGINE COOLANT TEMPERATURE
SWITCH
(a) Using an ohmmeter, check that there is no continuity
between the terminals when the engine coolant tem±
perature is above 93C (199F).
(b) Using an ohmmeter, check that there is continuity
between the terminals when the engine coolant tem±
perature is below 83C (181 F).
If continuity is not as specified, replace the switch. 2. DISCONNECT ENGINE COOLANT TEMPERATURE
SWITCH CONNECTOR
Check that the cooling fan rotates.
If not, check the cooling fan relay, cooling fan, engine
main relay and fuse, and check for a short circuit
between the cooling fan relay and engine coolant
temperature switch.
3. CONNECT ENGINE COOLANT TEMPERATURE

ON±VEHICLE INSPECTION
Low Temperature (Below 83
C (181F))
1. TURN IGNITION SWITCH ªONº
Check that the cooling fan stops.
If not, check the cooling fan relay and engine coolant
temperature switch, and check for a separated con±
nector or severed wire between the cooling fan relay
and engine coolant temperature switch.
High Temperature (Above 93C (199F))
4. START ENGINE
(a) Raise engine coolant temperature to above 93C
(199F).
(b) Check that the cooling fan rotates.
If not, replace the engine coolant temperature switch.

B. Inspect relay continuity
(a) Using an ohmmeter, check that there is continuity
between terminals 3 and 5.
(b) Check that there is continuity between terminals 2
and 4.
(c) Check that there is no continuity between terminals 1
and 2.
If continuity is not as specified, replace the relay. B. Inspect relay continuity
(a) Using an ohmmeter, check that there is continuity
between terminals 1 and 2.
(b) Check that there is continuity between terminals 3
and 4.
If continuity is not as specified, replace the relay.
C. Inspect relay operation
(a) Apply battery voltage across terminals 1 and 2.
(b) Using an ohmmeter, check that there is no continuity
between terminals 3 and 4.
If operation is not as specified, replace the relay.
D. Reinstall cooling fan relay
