my Tesla Model 3 has a coolant leak, what should I do

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the 12V battery to prevent electrical issues.

2. Drain Coolant

• Tools Required: Drain pan, wrench set
• Place a drain pan under the vehicle’s coolant drain valve.
• Open the drain valve and allow the coolant to completely drain out.
• Close the drain valve once all coolant has been removed.

3. Replace Damaged Hoses or Components

• Tools Required: Pliers, socket set, new coolant hoses or parts
• Identify and remove any damaged hoses or components (e.g., water pump, radiator).
• Install new hoses or components, ensuring they are securely fastened.
• Use hose clamps and tighten them to the manufacturer's specifications.

4. Refill Coolant

• Tools Required: Funnel, new coolant (Tesla-approved type)
• Use a funnel to fill the coolant reservoir with the appropriate type of coolant.
• Fill to the recommended level, checking for any signs of leaks as you fill.

5. Bleed Cooling System

• Tools Required: None specifically, but may require a coolant bleeder tool
• Start the vehicle and let it run until it reaches operating temperature.
• Monitor the temperature gauge and watch for air bubbles in the coolant reservoir.
• If air bubbles are present, open the bleed valve (if applicable) to release trapped air.

6. Final Check

• Inspect all connections for leaks after the vehicle has run.
• Reconnect the 12V battery and clear any error codes if necessary.
