what should I do if my Tesla Model S Original (2012-2020) has a coolant leak

Solution

1. Preparation

• Gather necessary tools, including a coolant pressure tester, socket set, and basic hand tools.
• Ensure the vehicle is parked on a flat surface and the battery is disconnected for safety.
• Allow the vehicle to cool down completely to prevent burns.

2. Locate the Leak

• Sub-step 1: Use the coolant pressure tester to pressurize the cooling system. Observe for any leaks while the system is under pressure.
• Sub-step 2: Visually inspect all identified components including hoses, reservoir, and pump to confirm the leak location.

3. Replace Damaged Components

• Sub-step 1: If the reservoir is cracked, remove it by disconnecting the hoses and unscrewing any retaining bolts.
• Sub-step 2: Install the new reservoir, ensuring all connections are secure and tight.
• Sub-step 3: For leaking hoses, use a socket set to remove the old hose clamps, replace the damaged hose, and reattach clamps tightly.
• Sub-step 4: If the water pump is leaking, remove it by disconnecting hoses and electrical connectors, then unscrew the mounting bolts. Install the new pump and reconnect all hoses and wiring.

4. Refill and Bleed the Cooling System

• Sub-step 1: Refill the cooling system with Tesla-approved coolant.
• Sub-step 2: Start the vehicle and allow it to reach operating temperature while keeping an eye on the coolant levels.
• Sub-step 3: Bleed air from the system by opening the air bleeder valve (if applicable) until coolant flows without bubbles.
