Common Signs of Overheating in the Tesla Model Y

Overheating in the Tesla Model Y can lead to serious damage if not addressed promptly. Here are the common signs to look out for:

Step 1: Visual Inspection

• Tools Required: Flashlight
• Check for any visible coolant leaks under the vehicle or around the battery pack. Inspect hoses for cracks or damage.

Step 2: Monitor Battery and Motor Temperatures

• Tools Required: Tesla Mobile App or Vehicle Touchscreen
• Access the temperature readings for both the battery and electric motors. Note the readings and compare them to the normal operating range.

Step 3: Check Cooling System Functionality

• Tools Required: OBD-II Scanner (if applicable)
• Use an OBD-II scanner to check for any error codes related to the battery or cooling system. Pay attention to any cooling system-specific codes.

Step 4: Inspect Cooling Fans and Components
