Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and in a safe environment.
Turn off the vehicle and allow it to cool down before starting repairs.

2. Check and Refill Coolant

Tools Required: Coolant funnel, appropriate coolant (Tesla-approved type).
Sub-steps:
- Locate the coolant reservoir under the front trunk.
- Remove the cap and check the coolant level. If low, add the appropriate Tesla-approved coolant until it reaches the recommended level.
- Secure the cap back on.

3. Inspect Cooling System Components

Tools Required: Visual inspection tools (flashlight) and possibly a hose clamp tool.
Sub-steps:
- Visually inspect all hoses and connections for signs of wear, cracks, or leaks.
- Check the radiator and cooling fans for debris or blockage.
- Replace any damaged hoses or components as necessary.

4. Test Cooling System Functionality

Tools Required: Multimeter (optional for electrical components).
Sub-steps:
- Reconnect the battery if it was disconnected.
- Start the vehicle and observe the operation of the cooling fans and coolant pump.
- If the fans are not operating, further diagnose electrical connections or replace the fan assembly if needed.

5. Clear Fault Codes

Tools Required: OBD-II scanner (Tesla-compatible).
Sub-steps:
- Connect the scanner to the vehicle’s OBD-II port.
- Clear any fault codes related to the overheating warning.
- Monitor the system to ensure that the warning does not return.
