Solution

1. Preparation

Ensure the vehicle is parked in a safe and level area.
Connect the vehicle to a charging station if needed; ensure it is powered during inspection.
Gather necessary tools and replacement parts.

2. Coolant Inspection and Replacement

Check Coolant Level
- Locate the coolant reservoir for the battery thermal management system.
- If the coolant level is low, add the appropriate Tesla-approved coolant to the recommended level.
Replace Coolant if Contaminated
- Drain the Old Coolant
  - Locate the drain valve on the coolant reservoir.
  - Use a suitable container to collect the old coolant.
  - Open the valve and allow the coolant to fully drain.
- Flush the System
  - Close the drain valve after draining.
  - Fill the reservoir with water to flush out any debris.
  - Run the cooling system for a few minutes, then drain again.
- Add New Coolant
  - Fill the reservoir with Tesla-approved coolant.
  - Ensure there are no air pockets in the system by running the cooling system and checking for leaks.

3. Fan and Pump Inspection

Test Cooling Fans
- Activate the vehicle’s cooling system through the Tesla app or vehicle interface.
- Listen for fan operation; if fans do not activate, further inspection of wiring and fuses may be required.
Inspect Coolant Pump
- Locate the coolant pump and check for any signs of damage or leaks.
- If faulty, replace the coolant pump according to the manufacturer's specifications.

4. Radiator and Hose Inspection

Examine Radiator
- Check the radiator for any blockage, dirt, or damage.
- Clean the exterior with compressed air if necessary.
Inspect Hoses
- Look for cracks, leaks, or damage on all coolant hoses.
- Replace any damaged hoses to ensure proper coolant flow.
