Solution

1. Preparation

Tools Required: OBD-II scanner, coolant tester, multimeter, socket set, torque wrench, safety gloves, and goggles.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Address Coolant Issues

Sub-steps:
1. If coolant levels are low, add the appropriate coolant (Tesla-approved type) until the proper level is reached.
2. If leaks are evident, replace damaged hoses or the radiator.
3. Inspect the reservoir for cracks, and replace if necessary.

3. Replace the Thermostat

Sub-steps:
1. Drain the coolant from the radiator using a drain pan.
2. Remove the thermostat housing bolts with a socket set.
3. Replace the thermostat with a new one, ensuring the gasket is replaced.
4. Reinstall the thermostat housing and torque bolts to manufacturer specifications (typically around 15-20 Nm).
5. Refill the cooling system with the correct coolant.

4. Repair or Replace Radiator Fans

Sub-steps:
1. Disconnect the battery to prevent electrical shock.
2. Remove the radiator fan assembly by unscrewing the mounting bolts.
3. Test the fan motor with a multimeter; replace if faulty.
4. Install the new or repaired fan and reconnect the wiring.
5. Reconnect the battery.

5. Clear Blockages

Sub-steps:
1. Use a hose to flush the radiator and remove any debris.
2. Inspect the air intake for any blockages and clear accordingly.
3. Ensure that the front grille is free from obstructions.
