Installation Notes and Tips

Verify the vehicle build date before ordering, especially for 2016 Tesla S applications, since this hose fits vehicles built to 3/31/16. Confirm left-side routing, inspect mating connectors and sealing surfaces, and replace any damaged clamps or retainers already present on the vehicle if required by the original setup. Before returning the vehicle to service, refill and bleed the cooling system according to Tesla procedures and check for leaks at both ends.
