Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shocks.
Gather tools and parts.

2. Replace the Radiator Fan Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box, typically under the dashboard or near the engine compartment.
Remove the fuse for the radiator fan and inspect it for continuity.
If blown, replace it with a fuse of the same amperage.

3. Replace the Radiator Fan Motor

Tools Required: Socket set, screwdrivers, multimeter
Disconnect the wiring harness from the fan motor.
Remove any mounting bolts securing the fan assembly to the radiator.
Carefully pull the fan assembly out of the engine bay.
Install the new fan motor by reversing the removal steps, ensuring all connections are secure.
Reconnect the battery.

4. Test the System

Start the engine and allow it to reach operating temperature.
Observe the radiator fan operation; it should activate as the engine temperature rises.
If the fan does not operate, further inspection of the wiring or the vehicle’s control module may be needed.
