Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Check tire pressure using a tire pressure gauge and inflate to manufacturer specifications found on the door jamb.
2. Inspect tread depth using a tread depth gauge; replace any tires with insufficient tread.
3. If tires are damaged, remove each tire using a socket set.
4. Install new tires, ensuring they are properly balanced and torqued to manufacturer specifications (typically 100-110 ft-lbs).

3. Brake Inspection and Replacement

Sub-steps:
1. Remove the wheel to access the brake assembly using a socket set.
2. Inspect brake pads for wear; replace if less than 3mm thick or showing uneven wear.
3. Inspect rotors for warping or discoloration; replace if necessary.
4. Reassemble the brake system and wheels, torquing lug nuts to manufacturer specifications.

4. Cooling System Check

Sub-steps:
1. Open the frunk and inspect the coolant reservoir for proper fluid levels.
2. Check for any obstructions around the cooling fans and motor.
3. If coolant levels are low, refill with Tesla-approved coolant to the appropriate level.
4. If the cooling system appears damaged, replace components as necessary.

5. Electrical Inspection

Sub-steps:
1. Inspect wiring harnesses and connections for signs of damage or overheating.
2. Use a multimeter to check for continuity in electrical circuits.
3. Replace any damaged wiring or connectors as needed.
