Repair Instructions

Step 1: Replace Blown Fuses/Relays

  1. Locate Fuse Box:

    • Find the fuse box under the dashboard and in the engine compartment.

  2. Inspect the Cooling Fan Fuse:

    • Identify the cooling fan fuse (refer to the owner's manual for the exact location).
    • Remove the fuse and check for continuity. Replace if blown.

  3. Test/Replace the Relay:

    • Remove the cooling fan relay from the fuse box.
    • Test the relay using the multimeter for continuity. If faulty, replace it with a new one.

Step 2: Repair or Replace the Cooling Fan

  1. Disconnect Battery:

    • Disconnect the negative terminal of the battery to prevent any electrical shock.

  2. Remove the Cooling Fan Assembly:

    • Disconnect the electrical connector from the fan.
    • Remove screws or bolts securing the fan assembly to the radiator shroud.
    • Carefully lift out the cooling fan assembly.

  3. Install New Fan:

    • Position the new fan in place of the old one.
    • Secure it with the screws or bolts removed earlier and reconnect the electrical connector.

Step 3: Test the System

  1. Reconnect Battery:

    • Reconnect the negative battery terminal.

  2. Start the Engine:

    • Allow the engine to reach operating temperature and observe if the cooling fan operates as expected.

  3. Monitor Performance:

    • Check for any overheating symptoms or warning lights.
Conclusion

If the cooling fan operates normally after these steps, the issue is resolved. If it still does not work, further diagnostics may be needed, such as checking the Engine Control Module (ECM) for faults or verifying the temperature sensor's operation. If the problem persists, it may be advisable to consult a professional technician for further assistance.
