RADIATOR FAN MOTOR
Ensure fan motor rotates when battery voltage is applied between connector terminals. (Scheme 1)- (Scheme 3). Ensure abnormal noises are not produced while motor is running.
Note. Testing of condenser fan motor is similar, but information is not available from manufacturer.

RADIATOR FAN RELAY (ELANTRA)
A radiator fan relay is used in radiator fan circuit. Relay is located in engine compartment fuse/relay box. Testing information is not provided by manufacturer. See wiring diagram to identify internal circuits for testing. (Scheme 5)
RADIATOR FAN RELAY (EXCEL & SCOUPE)
Two radiator fan relays (high and low) are used in radiator fan circuit. Relays are located in engine compartment fuse/relay box. Testing information is not provided by manufacturer. See wiring diagram to identify internal circuits for testing. (Scheme 6)
RADIATOR FAN RELAY (SONATA)
Two radiator fan relays (high and low) are used in radiator fan circuit. Relays are located in engine compartment fuse/relay box. Testing information is not provided by manufacturer. See wiring diagram to identify internal circuits for testing. (Scheme 7)- (Scheme 9).
RADIATOR FAN THERMOSWITCH (ELANTRA)
This system is equipped with 2 fan thermoswitches. Use ohmmeter and container of water to test switches. One thermoswitch controls radiator fan and is located on lower right radiator tank near radiator hose. Continuity should exist in switch at 179-191°F (82-88°C) and no continuity should exist at 178°F (81°C) or below. See A/C CONDENSER FAN for information on A/C thermoswitch.
RADIATOR FAN THERMOSWITCH (EXCEL & SCOUPE)
Use ohmmeter and container of water to test switch, located on lower radiator tank. Continuity should exist between switch terminals at 180-190°F (82-87°C). No continuity should exist at 172°F (78°C) or lower. Replace switch if not within specification.
RADIATOR COOLANT TEMPERATURE SWITCH (SONATA)
This system is equipped with 2 fan thermoswitches. Use ohmmeter and container of water to test switches. Radiator coolant temperature switch is located on lower right radiator tank near radiator hose. Continuity should exist in radiator coolant temperature switch at 189-199°F (87-93°C) and no continuity should exist at 181°F (83°C) or below. See A/C CONDENSER FAN for information on A/C thermoswitch.
CONDENSER FAN MOTOR
Power for condenser fan motor is provided through the 30-amp fusible link. The fusible link is located next to battery. Ensure fan motor rotates when battery voltage is applied between connector terminals. Ensure abnormal noises are not produced while motor is running.
CONDENSER FAN RELAY
On Sonata models, 2 condenser fan relays are used (high and low). On all models, ensure continuity is not present between relay terminals "L" and "B". If continuity is present, replace relay. When battery voltage and ground are applied to terminals "S1" and "S2", continuity should be present across terminals "L" and "B". (Scheme 4)
CONDENSER FAN THERMOSWITCH (ELANTRA)
A/C thermoswitch is located left of radiator fan thermoswitch and controls A/C condenser fan. Continuity should exist in A/C thermoswitch at 217-235°F (103-113°C). Continuity should not exist at any other temperature.
CONDENSER FAN THERMOSWITCH (SONATA)
A/C thermoswitch is located left of radiator coolant temperature switch. Continuity should exist in A/C thermoswitch from 217-223°F (103-107°C). No continuity should exist between 224-235°F (107-113°C).
