Why is the radiator fan not working on my Chevy Aveo?

Possible Causes of Radiator Fan Not Working on Chevy Aveo
There can be several reasons why the radiator fan is not working on your Chevy Aveo. Here are some possible causes based on the search results:
1. Defective thermostat, coolant sensor, or temperature switch: A bad thermostat, defective coolant sensor, or faulty temperature switch can prevent the radiator fan from engaging.
2. Faulty fan relay: A faulty fan relay can also cause the radiator fan to stop working.
3. Wiring problem: A blown fuse, loose or corroded connector, shorts, or opens in the wiring can lead to the radiator fan not working.
4. Low coolant level: Check the coolant level in the radiator. If it is too low, it can prevent the engine from reaching the temperature required to turn on the fan.
5. Worn-out fan clutch: The fan clutch, which controls the operation of the radiator fan, can wear out over time. If everything else seems fine, the springs in the fan clutch may have worn past the point of proper function.
6. Coolant temperature sensor: There may be a coolant temperature sensor on the radiator that controls the cooling fan. If this sensor is faulty, it can cause the fan not to turn on.
7. Blown fuse, bad relay, or broken wire: A blown fuse, a bad relay, or a broken wire can also be the cause of a malfunctioning radiator fan.
It’s important to note that these are just possible causes based on general information. To accurately diagnose and fix the issue, it is recommended to consult a professional mechanic or refer to the vehicle’s manual for specific troubleshooting steps.

The coolant temperature sensor monitors the temperature of the engine coolant and sends this information to the engine control module (ECM), which uses it to determine when to turn on the radiator fan.

What triggers the radiator fan to turn on?

engine temperature
The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees.
