Honda Civic Radiator Fan
How to Diagnose Honda Civic Radiator Fan Problems
One of the most essential parts of your car's cooling system is a Honda Civic radiator fan. It pushes cold air inside the radiator core to help cool down the temperature. It also dissipates heat from the coolant or antifreeze. The fan may experience several problems along the way, which can give you headaches. When it fails, you'll suffer from a series of engine overheating and stalling. You better be ready to do some troubleshooting if you feel that your radiator fan is starting to show symptoms of failure.
Inaccurate temperature reading from the thermostat
The amount of cool air needed in the car's cooling system is determined by the thermostat. But it won't give accurate temperature reading if the clutch in the radiator fan is broken. The clutch regulates the speed of the fan and turns the fan on when the engine requires cooling. To check the true condition of the clutch, inspect the fan thoroughly. Look for oil deposits around the center hub of the clutch. Leak is an indication of radiator fan failure. Also, try to move the fan clutch back and forth. If the fan seems to wobble a lot, the clutch must be replaced to restore the normal operation of the radiator fan.
Poor airflow within the vehicle's cooling system can lead to overheating. This problem is caused by a faulty fan shroud. When the fan shroud comes off from its mounting, the engine won't get enough enough cool air. That is because the fan shroud directs cold air straight to the engine. To inspect the shroud, look closely to the four mounting bolts. Make sure that they are complete. If any of them went missing, you must put a new one. Tighten the bolts using a socket wrench.
Inadequate supply of electricity
Lack of power explains why your radiator fan stops working. In this case, you should check the electrical system of your fan, which includes the wires and the fuses. Before you begin, disconnect the negative terminal from the battery first. Check the wires for corrosion. All rusty wires must be replaced. Also, check if the wires are properly attached together. If you see that the connections are loose, solder the wires or connect them with electrical tape. Check the fuse, too. Find fuse number 13 and inspect if its wires are burnt.
