Quick Answer
Unfortunately, the 2023 Tesla Model S, being an all-electric vehicle, does not have a serpentine belt. Serpentine belts are found in internal combustion engine (ICE) vehicles, where they drive accessories such as the alternator, power steering pump, air conditioning compressor, and water pump from the engine's crankshaft.
Electric vehicles like the Model S use electric motors to power the drivetrain and electrical systems. The functions typically handled by a serpentine belt in a gasoline car are either powered by dedicated electric motors (e.g., the A/C compressor) or are not present (e.g., a traditional power steering pump, as many EVs use electric power steering).
Therefore, there are no serpentine belt routing diagrams, belt lengths, rib counts, OEM part numbers, aftermarket cross-references, auto-tensioner part numbers, or idler pulley part numbers to provide for the 2023 Tesla Model S.
Why Electric Vehicles Don't Have Serpentine Belts
Traditional internal combustion engines rely on the rotational energy of the crankshaft to power various ancillary components. A serpentine belt is a crucial component in this system, transmitting power efficiently to multiple accessories.
In contrast, electric vehicles are fundamentally different. They are propelled by electric motors, and the power for essential functions like air conditioning, power steering (if not fully electric), and the 12V electrical system (which still exists in EVs) is sourced directly from the high-voltage battery pack, often converted and distributed as needed. The propulsion system is entirely electric, eliminating the need for an engine-driven belt system.
