Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Hoses

Sub-steps:
1. Remove any plastic covers obstructing access to hoses.
2. Inspect all coolant hoses for signs of bulging, cracking, or leaks.
3. If damaged, use a socket set to remove the old hose clamps and disconnect the hoses.
4. Install new hoses, ensuring they are secured with new clamps. Torque clamps to manufacturer specifications.

3. Replace Coolant

Sub-steps:
1. Drain the old coolant by locating the drain plug on the radiator and opening it.
2. Dispose of the old coolant according to local regulations.
3. Use a funnel to fill the system with new coolant, ensuring to use the recommended type (e.g., Tesla-approved coolant).
4. Run the engine with the radiator cap off to allow air to escape, topping off as needed.

4. Replace Thermostat (if necessary)

Sub-steps:
1. Locate the thermostat housing and remove the bolts using a socket set.
2. Carefully lift the housing off, noting the orientation of the thermostat.
3. Replace the old thermostat with a new one, ensuring it is seated correctly.
4. Reattach the housing and torque bolts to manufacturer specifications.

5. Check Water Pump Functionality

Sub-steps:
1. Locate the water pump and inspect for leaks or noise.
2. If faulty, remove the water pump by disconnecting any electrical connectors and hoses.
3. Install the new water pump, ensuring all connectors and hoses are properly attached.
