Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the vehicle from any charging source.
Allow the vehicle to cool down before starting work to prevent burns.

2. Coolant Level Check

Open the front trunk and locate the coolant reservoir.
Remove the cap and visually inspect the coolant level. If low, add Tesla-approved coolant until the proper level is reached.

3. Inspect and Replace Coolant Pump (if needed)

Tools Required: Socket set, screwdriver, coolant catch pan
Disconnect the battery to avoid electrical shock.
Remove any covers obstructing access to the coolant pump.
Disconnect the coolant hoses from the pump, allowing any remaining coolant to drain into the catch pan.
Unbolt the pump from its mount and replace it with a new unit.
Reconnect the hoses securely and ensure there are no leaks.

4. Air Intake Inspection

Check the front grille and air inlets for debris or obstructions.
Clean any debris found to allow proper airflow.
Ensure that any protective screens are not damaged or missing.

5. Test Cooling Fan Operation

Reconnect the battery and power the vehicle on.
Observe the cooling fans for proper operation; they should activate when the temperature rises.
If fans do not operate, investigate electrical connections or consider replacing the cooling fan assembly.
