Solution

1. Preparation

Sub-steps:
- Ensure the vehicle is parked on a level surface and the engine is off.
- Gather necessary tools and parts.

Tools Required:

Tesla diagnostic tool
Coolant pressure tester
Socket set
Screwdrivers

2. Coolant Check and Replacement

Sub-steps:
1. Open the front trunk to access the coolant reservoir.
2. Check the coolant level; if low, top off with the recommended Tesla coolant.
3. If necessary, perform a coolant flush:
  - Drain the existing coolant using a coolant pressure tester.
  - Refill with fresh Tesla-approved coolant according to the manufacturer's specifications.

3. Inspect and Test Cooling System Components

Sub-steps:
1. Inspect hoses for cracks or leaks; replace any damaged hoses.
2. Check the electric coolant pump:
  - Disconnect the electrical connector and use a multimeter to test for proper voltage.
  - If faulty, replace the pump with an OEM replacement.

4. Radiator and Fan Inspection

Sub-steps:
1. Remove the front grille to access the radiator and cooling fans.
2. Inspect the radiator for any obstructions or debris blocking airflow.
3. Test the cooling fans by applying 12V directly to the fan connectors to ensure they operate correctly; replace if they do not spin.
