Understanding your Daewoo Matiz’s cooling fan wiring diagram is crucial for diagnosing and fixing cooling system issues. The cooling fan plays a vital role in preventing your engine from overheating, especially during hot weather or stop-and-go traffic. This guide will take you through the intricacies of the Daewoo Matiz cooling fan wiring diagram, empowering you to troubleshoot problems effectively.
The Importance of a Functioning Cooling Fan
The cooling fan, often powered by an electric motor, pulls air through the radiator. This airflow helps dissipate heat from the coolant, which in turn prevents the engine from reaching critically high temperatures. A malfunctioning cooling fan can lead to overheating, potentially causing severe damage to your engine.
Common Cooling Fan Issues in Daewoo Matiz
Several issues can arise with your Daewoo Matiz’s cooling fan, including:
- Fan not turning on: This could be due to a faulty fan motor, a blown fuse, a malfunctioning temperature sensor, or a wiring problem.
- Fan running constantly: This could indicate a stuck relay, a faulty temperature sensor, or a problem with the engine control unit (ECU).
- Fan running at the wrong speed: This problem might point to a faulty fan resistor or a problem with the ECU.

Deciphering the Daewoo Matiz Cooling Fan Wiring Diagram
The wiring diagram for your specific Daewoo Matiz model can be found in your vehicle’s repair manual. This diagram provides a visual representation of the electrical circuit powering the cooling fan, outlining the connections between various components like:
- Battery: The power source for the cooling fan.
- Fuse: Protects the circuit from overloads.
- Relay: Acts as a switch, turning the fan on and off.
- Temperature sensor: Monitors the engine coolant temperature and signals the fan to turn on when necessary.
- Cooling fan motor: The component that directly powers the fan blades.

Troubleshooting Tips
Before diving into the wiring diagram, consider these basic troubleshooting steps:
-
Check the fuse: Locate the cooling fan fuse (refer to your owner’s manual) and inspect it visually or with a multimeter for continuity. Replace it if blown.
-
Inspect the fan motor: With the engine off, try spinning the fan blades by hand. If they don’t spin freely or feel resistant, the fan motor might be faulty and require replacement.
-
Test the temperature sensor: Consult your repair manual for the sensor’s location and resistance specifications. Test its resistance with a multimeter and compare it to the manufacturer’s values. A faulty sensor will need replacing.
Seeking Professional Help
While the Daewoo Matiz cooling fan wiring diagram can empower DIY enthusiasts, remember that working with electrical systems requires caution. If you’re uncomfortable tackling these repairs, it’s always best to consult a qualified mechanic.
