Solution

1. Preparation

Tools Required: Gloves, safety goggles, funnel, coolant (Tesla-approved type), rags
Ensure the vehicle is parked on a level surface and the engine is completely cool before starting work.

2. Check and Refill Coolant

Open the front trunk (frunk) and locate the coolant reservoir.
Inspect the coolant level against the minimum and maximum markings on the reservoir.
If the level is low, use a funnel to add Tesla-approved coolant until it reaches the maximum level.
- Note: Use only Tesla-approved coolant to avoid any compatibility issues.
Wipe any spilled coolant with a rag to prevent corrosion.

3. Inspect for Leaks

While the vehicle is stationary, inspect the ground under the vehicle for any signs of coolant leaks.
If leaks are found, inspect the hoses and connections for cracks or loose fittings.
Tighten any loose clamps and replace any damaged hoses as needed.

4. Test System

Start the vehicle and allow it to reach operating temperature.
Monitor the coolant temperature gauge and check for any warning messages.
If the warning message persists after refilling, further diagnosis may be required, such as checking the water pump or thermostat.
