Solution

1. Preparation

Tools Required: Tesla diagnostic tool, torque wrench, coolant refill kit, cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool before starting repairs.

2. Coolant Level Check and Refill

Open the front trunk (frunk) and locate the coolant reservoir.
Check the level against the minimum and maximum marks.
If low, add the appropriate coolant type (Tesla approved coolant) to the reservoir until it reaches the proper level.

3. Inspect and Replace the Radiator Fan

Locate the radiator fan assembly.
Disconnect the electrical connector to the fan.
Remove the mounting screws or clips securing the fan.
Replace with a new fan if it is not functioning correctly, ensuring proper alignment.
Reconnect the electrical connector and secure the fan assembly.

4. Check and Replace Water Pump

Locate the water pump (typically near the front of the vehicle).
Disconnect the electrical connector and any hoses attached to the pump.
Remove the mounting screws and take out the old pump.
Install the new water pump, ensuring all connections are secure.
Reconnect hoses and the electrical connector, and check for leaks.

5. Test the Cooling System

Start the vehicle and allow it to reach operating temperature.
Monitor the temperature gauge and ensure the radiator fan engages as necessary.
Check for any leaks around the coolant reservoir and hoses.
