Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Allow the engine to cool down completely before proceeding.
Gather necessary tools and replacement parts.

2. Check Coolant Level

Identify the coolant reservoir location.
Remove the coolant reservoir cap carefully to avoid burns.
If the coolant level is low, add the appropriate coolant mixture (Tesla recommends using their proprietary coolant).

3. Inspect Cooling System

Visually inspect hoses and connections for cracks or leaks.
Check the radiator for any obstructions or damage.
If leaks are found, replace damaged hoses or the radiator.

4. Test Cooling Fans

Turn on the vehicle and activate the climate control system.
Listen for the cooling fans to engage; they should operate quietly and smoothly.
If fans do not operate, inspect the fan motors for electrical issues or replace the fan assembly if necessary.

5. Replace Thermostat (if malfunctioning)

Locate the thermostat housing.
Disconnect any electrical connectors and hoses from the thermostat housing.
Remove the thermostat from the housing, noting its orientation.
Install a new thermostat, ensuring the correct orientation, and reassemble the housing.

6. Recheck System Functionality

Once repairs are completed, top off the coolant if necessary.
Run the engine and monitor for any overheating warnings.
Check for leaks around the repaired components.
