💡Installation Notes

Important: Always allow the cooling system to cool completely before beginning any service work to avoid scalding from hot coolant. We recommend professional installation by a qualified Tesla technician.

  1. After installation, refill the cooling system with Tesla recommended 50/50 mix ethylene glycol coolant (phosphate and nitrate free)

  2. Fill to the proper level between the MIN and MAX markings on the reservoir

  3. Perform a vacuum fill to avoid air trapped in the system

  4. Run the vehicle's built-in coolant air purge procedure through the service mode interface

  5. Check for leaks after the purge procedure is complete and recheck coolant level

Quality Guarantee: All PERFECTRAIL parts undergo strict quality testing and are backed by a 12-month warranty. We offer OEM/ODM custom services and support sample requests for qualified buyers.
