my Tesla Model 3 has a coolant leak, how to fix it

Solution

1. Preparation

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

2. Inspect and Identify Leak

• Tools Required: Flashlight, safety glasses
• Visually inspect the coolant reservoir, hoses, radiator, and water pump for any signs of damage or leaks.
• Use a pressure tester on the cooling system to identify hidden leaks.
• Mark any identified leaks for repair.

3. Replace Damaged Components

• Tools Required: Socket set, screwdrivers, wrench set, torque wrench
• Parts Required: Replacement hoses, coolant reservoir, radiator, or water pump as needed.
• Remove the damaged component (e.g., hose or reservoir) by loosening clamps and disconnecting it.
• Install the new component, ensuring proper fit and securing with clamps or bolts to manufacturer specifications (use torque wrench for proper torque settings).

4. Refill Coolant

• Tools Required: Funnel, coolant
• Remove the radiator cap and coolant reservoir cap.
• Using a funnel, refill the cooling system with the appropriate type of coolant (refer to the vehicle manual for specifications).
• Ensure the system is filled to the correct level and re-secure caps.

5. Test the System

• Reconnect the battery terminal.
• Start the engine and allow it to reach operating temperature while monitoring for leaks.
• Check the coolant level again and add more if necessary.
