Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.

2. Check and Refill Coolant

Locate the coolant reservoir.
Using a funnel, add the appropriate type of coolant (check owner's manual for specifications) until it reaches the maximum fill line.
Clean any spills immediately to prevent damage.

3. Inspect and Replace Cooling Fans (if necessary)

Disconnect the vehicle's battery to ensure safety.
Remove the front grille or any covers obstructing access to the cooling fans.
Use a multimeter to test the fans for proper voltage and operation.
If fans are faulty, remove the old fans and install new ones, ensuring they are properly connected.

4. Clear Air Intake Blockages

Inspect the air intakes for debris or obstructions.
Remove any foreign objects or dirt that could impede airflow.

5. Inspect and Replace Coolant Hoses (if needed)

Check all coolant hoses for cracks or leaks.
If damaged, use a socket set to disconnect the old hoses and replace them with new ones.
Ensure all connections are secure and leak-free.
