  1. Disconnect the negative battery cable.
  2.  
  3. Remove the fan shroud mounting bolts.
  4.  
  5. Disconnect the electrical harness from the fan motor.
  6.  
  7. Remove the fan and shroud as an assembly.
  8.  

To install:
  1. Position the fan and shroud assembly onto the radiator support and tighten the mounting bolts securely.
  2.  
  3. Connect the electrical harness for the fan motor.
  4.  
  5. Connect the negative battery cable.
  6.  
  7. Start the engine and check for proper fan operation.
  8.  

TESTING



See Figure 4

Fig. Fig. 4: Engine fan connectors have either two, three or four terminals. Apply battery voltage and ground to test the fan operation

If the engine fan fails to operate, there are 2 items to be checked; the first is the fan motor itself and the second is the thermo switch. When the coolant temperature climbs over 200°F, or the air conditioner is engaged, the engine fan should run.

Fig. Fig. 5: On some models, the engine fan connector is mounted to a clip at the lower left side of the radiator

  1. Disconnect the electrical harness from the engine fan.
  2.  
  3. Using fused jumper wires, apply battery voltage and ground to the appropriate terminals.
  4.  
  5. The fan should run smoothly, without abnormal noise or vibration. Replace the fan if the fan does not run or does not function.
  6.  
  7. Reconnect the engine fan electrical harness.
  8.  

Thermo Switch

See Figure 6

Fig. Fig. 6: The thermo sensor electrical connector is located at the bottom of the radiator near the sensor

The thermo switch, located either in the radiator or in the water pump, controls the operation of the engine fan. The switch completes an electrical circuit when the coolant temperature is above 200°F.

  1. Allow the vehicle to sit until the engine is completely cool.
  2.  
  3. Disconnect the switch electrical harness.
  4.  
  5. Using an ohmmeter, check resistance across the switch terminals.
  6.  
  7. Resistance should be as follows:

    Elantra, Tiburon and Accent SOHC-2.21-2.69 kilohms with a coolant temperature of 68°F (20°C).
     
    Excel, Scoupe, Sonata and Accent DOHC-2.27-2.73 kilohms with a coolant temperature of 68°F (20°C).
     

  8.  
  9. Start the engine and allow it to reach operating temperature.
  10.  
  11. Check resistance again. Resistance should be as follows:

    Elantra, Tiburon and Accent SOHC-264-328 ohms with a coolant temperature of 176°F (80°C).
     
    Excel, Scoupe, Sonata and Accent DOHC-290-354 ohms with a coolant temperature of 176°F (80°C).
     

  12.  
  13. If resistance is not as indicated, the switch is faulty.
  14.
