how to check for leaks in a Tesla Model S Original (2012-2020)

Solution

1. Preparation

• Tools Required: Safety goggles, gloves, flashlight, UV leak detection dye, UV light, pressure tester.
• Ensure the vehicle is parked on a flat surface.
• Allow the vehicle to cool down completely before inspection.

2. Inspect for Fluid Leaks

• Visual Inspection:

  • Use a flashlight to check under the vehicle for any obvious leaks.
  • Inspect around the coolant reservoir, brake fluid reservoir, and battery coolant connections.

• Using UV Leak Detection Dye:

  • Add UV leak detection dye to the coolant system as per manufacturer’s instructions.
  • Run the vehicle until it reaches operating temperature.
  • Turn off the vehicle and use a UV light to check for any glowing leaks.

3. Pressure Testing

• Using a Pressure Tester:
  • Connect the pressure tester to the coolant reservoir.
  • Pump the tester to the specified pressure (typically around 15-20 psi).
  • Monitor for any drop in pressure which indicates a leak; check hoses and connections while under pressure.

4. Brake Fluid Inspection

• Check the brake fluid reservoir for leaks, ensuring the cap is secure.
• Inspect brake lines for any signs of moisture or damage.
